General Description
The VSC880 is a 16x16 serial crosspoint switch with serial data rates at 2.125Gb/s. The VSC880 has been
designed to operate with the VSC870 backplane transceiver to establish a synchronous high performance switching
system with an aggregate bandwidth of 32Gb/s. The switch chip transmits the master word clock (62.5Mb/s), and
master cell clock (if used) to all port cards through the serial data channels. The transceivers automatically perform
bit alignment, word alignment and cell alignment to the switch chip. The transceiver and switch chip have been
optimized for both self-routing and cell-based systems and include special commands for connection requests (self-
routing) and cell synchronous operation (cell based). In addition, a parallel CPU interface can be used to control
internal modes and read status information from the switch. A 20-bit interface can also be used to program the switch
matrix in 4 clock cycles. The switch chip runs off of a 3.3V/2.5V or 3.3V/2.0V power supplies. The serial I/O buffers
contain on-chip termination resistors (see Application Note 34).

Parallel input signals used to program the switch matrix in 4
clock cycles when the signal CEN is LOW.
Parallel input signals used to program force IDLE words at
the switch matrix output in 4 clock cycles when the signal
CEN is LOW.
When CEN is held LOW, the inputs DATA[15:0] and FI[3:0]
can be used to program the switch matrix in 4 word clock
cycles timed to the WEN signal.
If CEN is LOW, this signal provides a synchronization pulse
for loading switch configuration data into DATA[15:0] and
FI[3:0].
The address to read and write data through parallel interface
CDATA[7:0].
This signal allows several switch chips to share an 8 bit data
bus connected to CDATA[7:0]. If CSEL is LOW, data will
be read or written to CDATA[7:0]. If CSEL is HIGH, the
outputs will be high impedance and the inputs disabled.
Bidirectional CPU interface for the status and control
registers. If CSEL is LOW, the data will be read or written
into this port. If CSEL is HIGH, the outputs will be high
impedance and the inputs will be disabled.
This signal is set HIGH to read the internal status registers
through the parallel interface CDATA[7:0]. It is set LOW to
write into this interface.
