APPLICATIONS
Cable equalization plus clock and data recovery for all high
speed serial digital interface applications involving SMPTE
259M and other data standards.
DESCRIPTION
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.
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.
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
(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.
