INTRODUCTION
The new GENLINX II GS9035A Serial Digital Reclocker is a high performance, serial digital reclocker offering clock and
data recovery for all high-speed serial digital interface applications. It can operate in either automatic or manual modes
making it ideal for both multi-rate serial data protocols (auto rate selection for five SMPTE data rates including: 143, 177,
270, 360 and 540Mb/s) and single rate data systems. The GS9035A is packaged as a 28-pin PLCC and is a drop-in
compatible replacement for the GS9035.
The new GS9035A is based on its predecessor - the GS9035 - and subsequently shares common device features including:
Large input jitter tolerance,
A single external VCO resistor for operation with 5 SMPTE data rates
Low jitter and low power consumption, and
A common PCB footprint
It is Gennum's intention to transition to the new GS9035A over the next 6-month period, and recommends that customers
begin qualifying the new device in both new and existing applications. Pre-production samples of the GS9035A are now
available.
OPTIMIZING GS9035A PERFORMANCE
For optimal device performance, Gennum recommends the implementation of new loop filter component values as outlined
in the Table 1.
Further device information and performance can be reviewed by referencing the updated GS9035A Preliminary Data Sheet
or by visiting the web-site at www.gennum.com.
