350m of high quality cable)
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
carrier detect with programmable threshold level
power savings mode (output serial clock disable)
large IJT, typically 0.56UI beyond loop bandwidth
robust lock detect
APPLICATIONS
Cable equalization plus clock and data recovery for all high
speed serial digital interface applications involving SMPTE
259M-C.
DESCRIPTION
The GS7025 provides automatic cable equalization and
high performance clock and data recovery for serial digital
signals. The GS7025 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 35dB of gain at
135MHz which typically results in equalization of greater
than 350m of high quality cable at 270Mb/s.
The GS7025 requires only one external resistor to set the
VCO centre frequency and provides adjustment free
operation.
The GS7025 has dedicated pins to indicate signal
strength, carrier detect, and LOCK. Optional external
resistors allow the carrier detect threshold level to be
customized to the user's requirement. In addition, the
GS7025 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 GS7025 operates from a
single +5 or -5 volt supply.
