General Description
The SY87725L is a single chip transceiver for data rates
up to 2.5Gbps. On the receive side, it includes a
complete clock recovery and data retiming circuit with
an integrated 4-bit serial-to-parallel data converter. On
the transmit side, it includes a synthesizer with an
integrated 4-bit parallel-to-serial data converter.
The SY87725L receiver has a synthesizer that
generates an internal clock from an externally supplied
TTL or PECL REFCLK that can be either 155.52MHz or
77.76MHz. This internal clock can be used by the clock
recovery PLL if an absence of transitions on the input
serial data stream prevents normal clock recovery. This
enables it to provide a stable clock source in the
absence of transitions on the incoming serial data
stream.
The transmit synthesizer uses the CLKIN parallel data
clock to generate its own serial rate clock locked to
CLKIN. This enables the transmit and receive to operate
at different data rates.
The serial interface for both the transmit and receive
functions feature industry standard high-speed
differential CML I/O. The parallel interfaces feature high-
speed LVDS I/O with an internal 100 termination on
the LVDS inputs.
The first bit for the serial-to-parallel conversion can be
moved using the RCV_SYNC input. The RCV_SYNC
input enables the parallel word boundary to move up in
time by one bit time for each pulse. This allows it to in
effect “swallow” one bit each time the RCV_SYNC pulse
is asserted.
