HDTV AUDIO/VIDEO CLOCK SOURCE ICS662-03

IDT™ / ICS™

HDTV AUDIO/VIDEO CLOCK SOURCE 1

ICS662-03 REV E 101807

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 provid e

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 requiremen t for an input

and output frequency not included here.

Application Information

Series Termination Resistor

Clock output traces should use series termination. To series

terminate a 50Ω trace (a common ly used trace impedance),

place a 33Ω resistor in series with the cloc k line, as close to

the clock outpu t pin as possible. The nom inal 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 connect ed

betwee n VDD (pin 2) and the PCB ground plane (pin 3).

PCB Layout Recommendations

For optimum device performance and lowest output pha se

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 k ept as short as possible , as should the PCB trace to the

ground via . Distance of the f errite bead and b ulk 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 compone nts 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 b ack). Other signa l 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 de vice.

Absolute Maximum Ratings

Stresses above the ratings listed below can ca use permanent damage to th e ICS662- 03. These r ating s , which are

standard values for ICS commercially rated parts, are stress rati ngs 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.
