Features
Description
PI6C3Q99X family provides following products:
PI6C3Q991:32-pinPLCCversion
PI6C3Q993:28-pinQSOPversion
Inputs are 5V I/O Tolerant
4 pairs of programmable skew outputs
Low skew: 200ps same pair; 250ps all outputs
Selectable positive or negative edge synchronization:
Excellent for DSP applications
ThePI6C3Q99Xfamilyisahighfanout3.3VPLL-basedclockdriver
intended for high performance computing and data-communica-
tions applications. A key feature of the programmable skew is the
abilityofoutputstoleadorlagtheREFinputsignal.ThePI6C3Q991
has 8 programmable skew outputs in 4 banks of 2, while the
PI6C3Q993 has 6 programmable skew outputs and 2 zero skew
outputs.Skewiscontrolledby3-levelinputsignalsthatmaybehard-
wiredtoappropriateHIGH-MID-LOWlevels.
Synchronous output enable
Output frequency: 3.75 MHz to 85 MHz
2x, 4x, 1/2, and 1/4 outputs
3 skew grades:
3-level inputs for skew and PLL range control
PLL bypass for DC testing
When the GND/sOE pin is held low, all the outputs are synchro-
nously enabled. However, if GND/sOE is held high, all the outputs
except3Q0and3Q1aresynchronouslydisabled.Furthermore,when
the V
/PE is held high, all the outputs are synchronized with the
CCQ
positive edge of the REF clock input. When V
/PE is held low,

devices have LVTTL outputs with 12mA balanced drive outputs.

Synchronous Output Enable. When HIGH, it stops clock outputs (except 3Q0 and 3Q1) in a LOW state - 3Q0
or 3Q1 may be used as the feedback signal to maintain phase lock. When TEST is held at MID level and
GND/sOE is HIGH, the nF [1:0] pins act as output disable controls for individual banks when nF [1:0] = LL.
Set GND/sOE LOW for normal operation.

flexibilitywithregardtoskewadjustment.TheFBsignaliscompared
with the input REF signal at the phase detector in order to drive the
VCO.PhasedifferencescausetheVCOofthePLLtoadjustupwards
or downwards accordingly. An internal loop filter moderates the
response of the VCO to the phase detector. The loop filter transfer
function has been chosen to provide minimal jitter (or frequency
variation) while still providing accurate responses to input fre-
quency changes.
Output skew with respect to the REF input is adjustable to compen-
sate for PCB trace delays, backplane propagation delays or to
accommodaterequirementsforspecialtimingrelationshipsbetween
clocked components. Skew is selectable as a multiple of a time unit
t which is of the order of a nanosecond (see Table 2). There are 9
U
skew configurations available for each output pair. These configu-
rations are choosen by the nF1:0 control pins. In order to minimize
the number of control pins, 3-level inputs (HIGH-MID-LOW) are
used,theyareintendedforbutnotrestrictedtohard-wiring.Undriven
3-level inputs default to the MID level. Where programmable skew
isnotarequirement,thecontrolpinscanbeleftopenforthezeroskew

select specific skew taps by using the nF1:0 control pins.

Notes:
1. The device may be operated outside recommended frequency ranges without damage, but functional
operation is not guaranteed. Selecting the appropriate FS value based on input frequency range allows the
PLL to operate in its sweet spot where jitter is lowest.
2. TheleveltobesetonFSisdeterminedbythenominaloperatingfrequencyoftheVCOandTimeUnitGenerator.
The VCO frequency always appears at 1Q1:0, 2Q1:0, and the higher outputs when they are operated in their
undivided modes. The frequency appearing at the REF and FB inputs will be the same as the VCO when the
output connected to FB is undivided. The frequency of the REF and FB inputs will be 1/2 or 1/4 the VCO
frequencywhenthepartisconfiguredforafrequencymultiplicationbyusingadividedoutputastheFBinput.
3. Skew adjustment range assumes that a zero skew output is used for feedback. If a skewed Q output is used
for feedback, then adjustment range will be greater. For example if a 4t skewed output is used for feedback,
U
all other outputs will be skewed 4t in addition to whatever skew value is programmed for those outputs.
U
Max adjustment range applies to output pairs 3 and 4 where ±6 t skew adjustment is possible and at the
U
lowest F
value.

divided outputs change on the negative edge of REF, and the positive edges of the divide-by-2 and the divide-by-4 signals align.
Skew:
The time between the earliest and the latest output transition among all outputs for which the same tU delay has been selected when all are
loaded with 20pF and terminated with 75Ohm to VCC/2.
tSKEWPR: The skew between a pair of outputs (xQ0 and xQ1) when all eight outputs are selected for 0tU.

tDEV

tLOCK
:
The skew between outputs when they are selected for 0t U.
:
The output-to-output skew between any two devices operating under the same conditions (VCC, ambient temperature, air flow, etc.)
The deviation of the output from a 50% duty cycle. Output pulse width variations are included in tSKEW2 and tSKEW4 specifications.
The time that is required before synchronization is achieved. This specification is valid only after VCC is stable and within normal operating
limits. This parameter is measured from the application of a new signal or frequency at REF or FB until tPD is within specified limits.
:
:
tPWH is measured at 2.0V.
tPWL is measured at 0.8V.
tORISE and tOFALL are measured between 0.8V and 2.0V.
