Delta39K™ PLL and Clock Tree

The Delta39K PLL and the global clock tree provide design-

Introduction

ers with functionality that can be configured to meet various

design requirements. This functionality includes clock phase

adjustment, clock multiplication and division, Spread Aware™

feature, lock detection, off-chip clocking and buffering, and

JTAG support.

The purpose of this application note is to provide information

and instruction in utilizing the functionality of the Delta39K™

Phase-Locked Loop (PLL) and associated clock tree.

Delta39K is a family of high-density Complex Programmable

Logic Devices (CPLDs) containing on-chip components such

as Single-Port RAM, advanced Dual-Port RAM, and a PLL.

The Delta39K PLL can be used in any system requiring clock

frequency or clock phase manipulation.

Clock Phase Adjustment

Designers may use the PLL and clock tree to re-position the

edges of the PLL-generated clock in order to shift perfor-

mance toward either improved set-up time or improved

clock-to-out time. The clock's phase, or the position of its edg-

es relative to the PLL input, may be adjusted in either of two

ways: Skewing the clock moves its phase backward on the

time axis, while de-skewing the clock moves its phase fore-

word on the time axis.

For Delta39K, programming is defined as the loading of a

user’s design into the on-chip FLASH device internal to the

Delta39K package. Configuration, on the other hand, is the

loading of a user’s design into the volatile Delta39K die.

Overview of PLL & Clock Tree

Within each 3.3V/2.5V Delta39K device, a single on-chip PLL

resides as part of a larger clocking scheme. Four local dedi-

cated clock input pins, referred to here as GCLK[3:0], provide

direct inputs to this clock tree. GCLK[0] and GCLK[1] may

also be used as an input port and external feedback port,

respectively to the PLL. Within the clock tree are four global

clocks, referred to here as INTCLK[3:0], which are accessible

to any macrocell, I/O cell, or memory block. GCLK[3:0] and

the outputs of the PLL feed a set of multiplexors which source

INTCLK[3:0]. Figure 1 contains a block diagram of the clock

tree and PLL.

There are eight options for skewing the incoming clock. The

clock can be skewed so that the phase is delayed 0°, 45°, 90°,

135°, 180°, 225°, 270°, or 315°. A 45° phase shift increment

is equal to a delay of 1/8th of the clock's period length. Note

that adding delay to the incoming clock has the effect of in-

creasing effective clock-to-out time while decreasing the ef-

fective setup time requirements. Refer to Figure 2 for an ex-

ample.

Figure 3. De-skewed Clock and Adjusted t_Sand t_CO

There are two options for de-skewing a clock using the PLL.

Both of these involve the insertion of a delay into the PLL

feedback path, which decreases the effective clock-to-out

time by the delay value but increases the effective set-up time

requirement by the same amount. Please see Figure 3 for a

description of this.

If EXTERNAL is selected as the method of feedback, only

Phase 0 may be selected as the phase adjustment option

value in the LPM instantiation for the on-chip global clock that

drives the off-chip clock used as the external feedback. If

CLOCK_TREE or DIRECT is selected, any of the eight phas-

es may also be selected. The four global clocks, INTCLK[3:0],

may be inverted locally at the macrocell register or I/O register

used in order to create additional phases. The resulting phase

delay would be 180° for clocks that have been generated by

the PLL and have passed through a divider with a binary di-

vide value (1, 2, 4, 8, or 16). The phase delay is the same for

clocks that have been derived directly from one of the

GCLK[3:0] input pins without using the PLL. However, if any

of these global clocks have been generated by the PLL and

pass through a divider with a non-binary divide value (3, 5, or

6), the amount of phase delay will vary based on their

non-50% duty cycles.

The first option is to insert a delay equal to the delay of the

clock tree in the 39K by selecting the feedback path labeled

“CLOCK_TREE” in Figure 1.

The second option is to feedback a PLL-generated off-chip

clock through the GCLK[1] pin to ext_fdbk. This means that

whatever delay that is associated with the connection be-

tween the off-chip clock and GCLK[1] will become included in

the PLL’s feedback path. This delay will directly determine to

what extent gclk0-3 are de-skewed. This path is indicated as

a dashed line and is labeled “EXTERNAL” in Figure 1.

Using the DIRECT feedback path means that an internal

trace directly connects the PLL output to the PLL feedback

input. This configuration should be used when no de-skew is

desired. This path is labeled “DIRECT” in Figure 1.

Clock Multiplication and Division

Designers may use the PLL and Clock Tree to multiply or di-

vide the incoming clock to generate multiple frequencies, to

increase or decrease incoming clock speeds, or to correct the

incoming clock’s duty cycle.

When gclk0-3 have been derived from any of the 7 phase-de-

layed or skewed PLL outputs, selecting CLOCK_TREE or

EXTERNAL as the method of feedback in order to implement

de-skew will cancel part or all of this skew. Therefore, it is not

possible to improve set-up and clock-to-out times simulta-

neously on a single clock.

The clock can be multiplied by a factor of 1, 2, 4 or 8. Each

multiply option selects an element, which is effectively a

counter or divider set to the appropriate value, for use in the

feedback path. The result is a PLL-generated clock that is

either the same speed as or is multiplied up to 8 times faster

than the incoming clock.

Selecting a Phase Adjustment Option

Only one of the three feedback option values may be inserted

into the LPM instantiation. Selecting the EXTERNAL option

will require the use of an off-chip clock, and will constrain the

number of valid values that may be selected for the Multipli-

cation/Division and Phase Adjustment options. To view these

constraints, please see Tables 1, 2 and 4.

The PLL-generated clock may be divided by one of eight fac-

tors after the incoming clock has been multiplied. Division se-

lections are 1, 2, 3, 4, 5, 6, 8, and 16.

Selecting a Multiplication/Division Option

The Voltage Controlled Oscillator (VCO), the core of the

Delta39K PLL is designed to operate within the frequency

range of 100 MHz to 266 MHz. When using the DIRECT or

CLOCK_TREE feedback configurations the pll_in frequency

(GCLK0) and multiply option must be selected to ensure the

VCO is operating within this range. Valid pll_in frequencies for

each multiply option are detailed in Table 3. Note the maxi-

mum input frequency to the PLL is limited to 133MHz. In these

Delta39K PLL and Clock Tree

configurations any one of the eight division settings may be

individually selected for gclk[0-3].

Table 4. Valid Multiply & Divide Options: EXTERNAL

Selected

When the EXTERNAL feedback option is selected only mul-

tiplication by a factor of one and division by a factor of one

may be selected for the off-chip clock that is being used in the

feedback path. The other three PLL generated clocks may

use any of the eight division settings. Valid pll_in frequencies,

multiply and divide options for this configuration are detailed

in table 4.

Note that if an on-chip clock is sent off-chip, it will be further

Multiplying an input frequency allows one to use slower fre-

quencies throughout the board (externally) and use faster fre-

quencies internally. (Assuming they are not needed other

places so as to make this less advantageous). This allows for

less power consumption, less electromagnetic interference

(EMI), and less undesirable high speed signal integrity is-

sues.

Spread Aware™ Feature

The PLLs incorporated in all Delta39K CPLDs are Spread

Aware. This feature refers to the ability of the PLL to track a

spread-spectrum input clock such that its spread is seen on

the output clock. Spread-spectrum is a method of 'spreading'

or modulating a fundamental or original frequency in a con-

trolled, oscillatory manner, such that the electromagnetic en-

ergy broadcast at any given component in the frequency

spectrum is below the maximum value imposed by FCC reg-

ulations. Spread Aware does not mean that the PLL is capa-

ble of generating a spread-spectrum output from a non

spread-spectrum input.

Also, designs requiring a given throughput or bandwidth run-

ning at a lower frequency and wider bus-width, can be in-

creased to a higher frequency, while the bus-width can be

reduced to a narrower width. This way, less logic resources

(real estate) can be used on the Cypress CPLD, while main-

taining the same throughput.

Designers may choose to use the spread aware Delta39K

PLL with a spread spectrum input clock. Down spread, up

spread, or some form of middle spread such as center spread

may be used on the incoming clock. However, the total

amount of spread in either or both directions should be limited

to 0.6% of the fundamental frequency. The modulation fre-

quency of the spread should be 50 kHz or less in order to

ensure that the PLL will meet the performance specified in the

data sheet and maintain its intended 1 MHz loop bandwidth.

Lock Detection

A finite amount of time is required from the moment that the

incoming clock signal is placed on the GCLK[0] pin, and thus

drives the source of the PLL, to the time that the PLL actually

achieves steady-state operation, or lock. Designs that contain

logic that will not operate properly until a valid clock signal is

present at the output of the PLL, are dependent upon the PLL

first achieving lock. Designs such as these may require a sig-

nal to indicate when the PLL has reached lock. The PLL can

be configured to generate a lock detect signal at a dedicated

I/O pin. This pin is fed by a multiplexor that can be configured

to select either a general-purpose I/O function or a lock de-

tection indicator function for this pin.

Notes:

2. An off-chip clock is the output of a toggle flip-flop, which acts as a /2.

3. When an off-chip clock is fed back to ext_fdbk, the toggle flip-flop is effectively placed into the feedback path, resultingin an implicit x2 on top of the x1 multiplication

setting.

JTAG Support

input clkin;

The Delta39K PLL supports the JTAG instruction INTEST.

When the Delta39K device is in JTAG mode and is executing

the instruction INTEST, the clock driving the TCK pin is mul-

tiplexed onto INTCLK[3:0]. This allows the internal logic to be

controlled by the JTAG clock, TCK, instead of the system

clock, and enables the user to verify proper operation of his

or her design in a given device. For more information about

JTAG programming, please refer to the application note titled

Off-Chip Clocking and Buffering

begin

The Delta39K global clocks, INTCLK[3:0], may be driven

off-chip by clocking a macrocell or I/O register configured as

a toggle flip-flop (TFF). This way, upon every rising edge of

the INTCLK clock used, the register output level will toggle

from its current state (HIGH or LOW) to the opposite state

(LOW or HIGH). Since, for every two rising edges of the IN-

TCLK clock used a single rising edge at the register output is

generated, a periodic signal that is half the frequency of the

ment off-chip clocks in source code, sample code in both

VHDL and Verilog is listed below:

if (plloutclock)

offchipclock <= ~( offchipclock);

end

endmodule

Listing 1b: Verilog Example of Off-chip Clock

Multiple identical output clocks can be buffered from a single

global clock by driving multiple outputs or 'copies' to the same

output described, above.

Overview of Software Support

The Delta39K PLL can be configured in either VHDL or Ver-

ilog code using Warp Enterprise™, Warp Professional™, or

Warp® Release 6.0 or later software. The methodology for

implementing this configuration is via a component, module,

or LPM instantiation. Since Delta39K contains a single PLL,

each design project should contain only one instantiation of

the PLL.

Selecting a Target Device

When creating a new project or editing a current project to

target a device, only 2.5V/3.3V devices in the Delta39K family

should be selected if PLL functionality is desired. These de-

vices are indicated by a 'V' in the package name, while low

voltage device selections include a “Z” in the package name

and do not offer PLL functionality. An example of such a de-

vice selection is “CY39100V676-125MBC”.

Component / Module or LPM Instantiation

The PLL configuration may be implemented by instantiating

the PLL component “cy_c39kpll.” For Warp to recognize

these instantiations, the user must place the appropriate

VHDL 'library' and 'use' statements or Verilog ‘include’ state-

ments in the source code file where the PLL instantiation re-

sides. For an example of the PLL instantiation in source code,

please see Listing 2a and 2b. In these samples, 'clkin' is mul-

tiplied by 4, while clock signals 'm1p0clock', 'm2p45clock',

'm4p0clock', and 'm4p90clock' are internal clocks accessible

to every register on the selected Delta39K device. Each of the

four internal clocks is configured with different divide and

phase shift selections. 'm1p0clock' is also configured to tog-

gle 'off chip clock' as an off-chip clock. The method of feed-

back selected is 'DIRECT'.
