General Description

The VSC835 is a monolithic 34x34 asynchronous crosspoint switch, designed to carry broadband data

streams at up to 2.5 Gbit/s. The non-blocking switch core is programmed through a parallel port interface that

allows random access programming of each output port. A high degree of signal integrity is maintained through

the chip through fully differential signal paths.

The crosspoint function is based on a multiplexer tree architecture. Each data output is driven by a 34:1

multiplexer tree that can be programmed to one and only one of its 34 inputs, and each data input can be routed

to multiple outputs. The signal path is unregistered, so no clock is required for the data inputs. The signal path is

asynchronous, so there are no restrictions on the phase, frequency, or signal pattern at each input. Each input

channel and each output channel has an signal monitor function that can be used to identify loss of activity

(LOA). An interrupt pin is provided to signal LOA, after which an external controller can query the chip to

determine the channel(s) on which the fault occurred.

Each output driver is a fully differential switched current driver with on-die back-terminations for maxi-

mum signal integrity. Data inputs are terminated on die through 50 ohm resistors terminated to V

TERM

The parallel interface uses TTL levels, and provides address, data, and control pins that are compatible

with a microprocessor-style interface. The control port provides access to all chip functions, including LOA and

programming. Program buffering is provided to allow multiple program assignments to be queued and issued

simultaneously via a single configure command.
