HDTV Audio/Video Clock Source

Description

The ICS662-03 provides synchronous clock generation

for audio sampling clock rates derived from an HDTV

stream. The device uses the latest PLL technology to

provide superior phase noise and long term jitter

performance. The device also supports a 27 MHz

output clock for video MPEG applications from an

HDTV reference clock.

Please contact ICS if you have a requirement for an

input and output frequency not included here.

Features

•Packaged in 8-pin SOIC

•Available in Pb (lead) free package

•HDTV clock input

•Low phase noise

•Exact (0 ppm) multiplication ratios

•Support for 256 and 384 times sampling rate

•Supports 27 MHz output for video (MPEG)

ICS662-03

Application Information

Series Termination Resistor

Clock output traces should use series termination. To

series terminate a 50Ω trace (a commonly used trace

impedance), place a 33Ω resistor in series with the

clock line, as close to the clock output pin as possible.

The nominal impedance of the clock output is 20Ω.

Decoupling Capacitors

As with any high performance mixed-signal IC, the

ICS662-03 must be isolated from system power supply

noise to perform optimally.

Decoupling capacitors of 0.01µF must be connected

between VDD (pin 2) and the PCB ground plane (pin

3).

PCB Layout Recommendations

For optimum device performance and lowest output

phase noise, the following guidelines should be

observed.

1) Each 0.01µF decoupling capacitor should be

mounted on the component side of the board as close

to the VDD pin as possible. No vias should be used

between decoupling capacitor and VDD pin. The PCB

trace to VDD pin should be kept as short as possible,

as should the PCB trace to the ground via. Distance of

the ferrite bead and bulk decoupling from the device is

less critical.

2) To minimize EMI and obtain the best signal integrity,

the 33Ω series termination resistor should be placed

close to the clock output.

3) An optimum layout is one with all components on the

same side of the board, minimizing vias through other

signal layers (the ferrite bead and bulk decoupling

capacitor can be mounted on the back). Other signal

traces should be routed away from the ICS662-03. This

includes signal traces just underneath the device, or on

layers adjacent to the ground plane layer used by the

device.

Absolute Maximum Ratings

Stresses above the ratings listed below can cause permanent damage to the ICS662-03. These ratings,

which are standard values for ICS commercially rated parts, are stress ratings only. Functional operation of

the device at these or any other conditions above those indicated in the operational sections of the

specifications is not implied. Exposure to absolute maximum rating conditions for extended periods can

affect product reliability. Electrical parameters are guaranteed only over the recommended operating

temperature range.
