GENLINX II GS9025A

Serial Digital Receiver

PRELIMINARY DATA SHEET

FEATURES

DESCRIPTION

• SMPTE 259M compliant

• operational to 540Mb/s

The GS9025A provides automatic cable equalization and

high performance clock and data recovery for serial digital

signals. The GS9025A receives either single-ended or

differential serial digital data and outputs differential clock

and retimed data signals at PECL levels (800mV). The on-

board cable equalizer provides up to 40dB of gain at

200MHz which typically results in equalization of greater

than 350m of high quality cable at 270Mb/s.

• automatic cable equalization (typically greater than

350m of high quality cable at 270Mb/s)

• adjustment-free operation

• auto-rate selection (5 rates) with manual override

• single external VCO resistor for operation with five

input data rates

The GS9025A operates in either auto or manual data rate

selection mode. In both modes, the GS9025A requires only

one external resistor to set the VCO centre frequency and

provides adjustment free operation.

• data rate indication output

• serial data outputs muted and serial clock remains

active when input data is lost

• operation independent of SAV/EAV sync signals

• signal strength indicator output

The GS9025A has dedicated pins to indicate signal

strength/carrier detect, LOCK and data rate. Optional

external resistors allow the carrier detect threshold level to

be customized to the user's requirement. In addition, the

GS9025A provides an 'Output Eye Monitor Test'

(OEM_TEST) for diagnostic testing of signal integrity after

equalization, prior to reslicing. The serial clock outputs can

also be disabled to reduce power. The GS9025A operates

from a single +5 or -5 volt supply.

• carrier detect with programmable threshold level

• power savings mode (output serial clock disable)

APPLICATIONS

Cable equalization plus clock and data recovery for all high

speed serial digital interface applications involving SMPTE

259M and other data standards.
