Applications Sections
This section illustrates the various operating modes of
the SY87725L with the appropriate control signals.
Normal Data Flow
Receive Section
The diagram below shows the data paths in a normal
operating mode. In this case, downstream data at a
serial rate of 2.5Gbps is arriving at SIN and the
recovered 4-bit parallel data is exiting at DOUT at
625Mbps. This is not the double data rate mode
(DDR) so the parallel rate is the serial rate ÷ 4.
Transmit Section
On the transmit side, the upstream data appears at
DIN in a 4-bit wide parallel format at 312.5Mbps and
exits at SOUT at a 1.25Gbps serial rate. The CLKIN
input is synchronous with the parallel data at DIN.
The loopback control signals RCV_CNTRL0,
RCV_CNTRL1, XMT_CNTRL0, XMT_CNTRL1 shown
in the table below select the clock and data paths for
normal operation. The RCV_DDRSel input is selecting
the CLKOUT to be in normal rate (÷ 4) mode.
