LVDS/LVCMOS CLOCK GENERATOR
ICS8402010I
GENERAL DESCRIPTION
FEATURES
ICS8402010I is a low phase noise Clock Generator
• Three banks of outputs:
ICS
HiPerClockS™
and is a member of the HiperClockS™family of high
performance clock solutions from IDT. The device
Bank A/B: three single-ended LVCMOS outputs at 16.66MHz
Bank C: three differential LVDS outputs at 62.5MHz
One single-ended reference clock output at 25MHz
provides three banks of outputs and a reference
clock. Each bank can be independently enabled by
using output enable pins. A 25MHz, 18pF parallel resonant
crystal is used to generate the 16.66MHz, 62.5MHz and 25MHz
frequencies. The typical RMS phase jitter for this device is less
than 1ps.
• Crystal input frequency: 25MHz
• Maximum output frequency: 62.5MHz
• RMS phase jitter @ 62.5MHz, using a 25MHz crystal,
Integration Range (1.875MHz - 20MHz): 0.375ps (typical)
• Full 3.3V operating supply
• -40°C to 85°C ambient operating temperature
• Available in both standard (RoHS 5) and lead-free (RoHS6)
packages

APPLICATION INFORMATION
POWER SUPPLY FILTERING TECHNIQUES
As in any high speed analog circuitry, the power supply pins are
vulnerable to random noise. To achieve optimum jitter perfor-
mance, power supply isolation is required. The ICS8402010I pro-
vides separate power supplies to isolate any high switching noise
from the outputs to the internal PLL. VDD, VDDA and VDDO_X should
be individually connected to the power supply plane through
vias, and 0.01µF bypass capacitors should be used for each pin.
Figure 1 illustrates this for a generic VCC pin and also shows that
VDDA requires that an additional 10Ω resistor along with a 10µF
bypass capacitor be connected to the VDDA pin.

RECOMMENDATIONS FOR UNUSED INPUT AND OUTPUT PINS

LVCMOS OUTPUTS
LVCMOS CONTROL PINS
All unused LVCMOS output can be left floating. There should be
no trace attached.
Control pins have internal pullups or pulldowns; additional
resistance is not required but can be added for additional
protection. A 1kΩ resistor can be used.
LVDS OUTPUTS
All unused LVDS outputs should be terminated with 100Ω resistor
between the differential pair.

CRYSTAL INPUT INTERFACE
The ICS8402010I has been characterized with 18pF parallel
resonant crystals. The capacitor values shown in Figure 2 below
were determined using a 25MHz, 18pF parallel resonant crystal
and were chosen to minimize the ppm error.

(Ro) plus the series resistance (Rs) equals the transmission
line impedance. In addition, matched termination at the crystal
input will attenuate the signal in half. This can be done in one
of two ways. First, R1 and R2 in parallel should equal the
transmission line impedance. For most 50Ω applications, R1
and R2 can be 100Ω. This can also be accomplished by
removing R1 and making R2 50Ω.
The XTAL_IN input can accept a single-ended LVCMOS
signal through an AC couple capacitor. A general interface
diagram is shown in Figure 3. The XTAL_OUT pin can be left
floating. The input edge rate can be as slow as 10ns. For
LVCMOS inputs, it is recommended that the amplitude be
reduced from full swing to half swing in order to prevent signal
interference with the power rail and to reduce noise. This
configuration requires that the output impedance of the driver

LVDS DRIVER TERMINATION
A general LVDS interface is shown in Figure 4. In a 100Ω
differential transmission line environment, LVDS drivers
require a matched load termination of 100Ω across near
the receiver input. For a multiple LVDS outputs buffer, if only
partial outputs are used, it is recommended to terminate the
unused outputs.

VFQFN EPADTHERMAL RELEASE PATH
In order to maximize both the removal of heat from the package
and the electrical performance, a land pattern must be
incorporated on the Printed Circuit Board (PCB) within the footprint
of the package corresponding to the exposed metal pad or
exposed heat slug on the package, as shown in Figure 5. The
solderable area on the PCB, as defined by the solder mask, should
be at least the same size/shape as the exposed pad/slug area on
the package to maximize the thermal/electrical performance.
Sufficient clearance should be designed on the PCB between the
outer edges of the land pattern and the inner edges of pad pattern
for the leads to avoid any shorts.
are application specific and dependent upon the package power
dissipation as well as electrical conductivity requirements. Thus,
thermal and electrical analysis and/or testing are recommended
to determine the minimum number needed. Maximum thermal
and electrical performance is achieved when an array of vias is
incorporated in the land pattern. It is recommended to use as
many vias connected to ground as possible. It is also
recommended that the via diameter should be 12 to 13mils (0.30
to 0.33mm) with 1oz copper via barrel plating. This is desirable to
avoid any solder wicking inside the via during the soldering process
which may result in voids in solder between the exposed pad/
slug and the thermal land. Precautions should be taken to
eliminate any solder voids between the exposed heat slug and
the land pattern. Note: These recommendations are to be used
as a guideline only. For further information, refer to the Application
Note on the Surface Mount Assembly of Amkor’s Thermally/
Electrically Enhance Leadfame Base Package, Amkor Technology.
While the land pattern on the PCB provides a means of heat
transfer and electrical grounding from the package to the board
through a solder joint, thermal vias are necessary to effectively
conduct from the surface of the PCB to the ground plane(s). The
land pattern must be connected to ground through these vias.
The vias act as “heat pipes”. The number of vias (i.e.“heat pipes”)

POWER CONSIDERATIONS
This section provides information on power dissipation and junction temperature for the ICS8402010I.
Equations and example calculations are also provided.
1. Power Dissipation.
The total power dissipation for the ICS8402010I is the sum of the core power plus the power dissipated in the load(s).
The following is the power dissipation for V = 3.3V + 5ꢀ = 3.465V, which gives worst case results.

2. Junction Temperature.
Junction temperature, Tj, is the temperature at the junction of the bond wire and bond pad and directly affects the
TM
reliability of the device. The maximum recommended junction temperature for HiPerClockS devices is 125°C.
The equation for Tj is as follows: Tj = θJA * Pd_total + TA
Tj = Junction Temperature
θ
= Junction-to-Ambient Thermal Resistance
JA
Pd_total = Total Device Power Dissipation (example calculation is in section 1 above)
TA = Ambient Temperature
In order to calculate junction temperature, the appropriate junction-to-ambient thermal resistance θ must be used.
JA
Assuming no air flow and a multi-layer board, the appropriate value is 37°C/W per Table 6.
Therefore, Tj for an ambient temperature of 85°C with all outputs switching is:
85°C + 0.316W * 37°C/W = 96.7°C. This is below the limit of 125°C.
This calculation is only an example. Tj will obviously vary depending on the number of loaded outputs, supply voltage, air
flow, and the type of board.
