TQ8017

Typical output waveform with

all channels driven

The TQ8017 is a non-blocking 16 x 16 digital crosspoint switch capable of

data rates greater than 1.25 Gigabits per second per port. Utilizing a fully

differential internal data path and PECL I/O, the TQ8017 offers a high data

rate with exceptional signal fidelity. The symmetrical switching and noise

rejection characteristics inherent in differential logic result in low jitter and

signal skew. The TQ8017 is ideally suited for digital video, data

Features

• >20 Gb/s aggregate BW

• 1.25 Gb/s/port NRZ data rate

• Non-blocking architecture

• 500 ps delay match

communications and telecommunication switching applications.

• Differential PECL-level data

I/O; Selectable CMOS/TTL-

level control inputs

The non-blocking architecture uses 16 fully independent 16:1 multiplexers

(see diagram on page 2), allowing each output port to be independently

programmed to any input port. The switch is configured by sequentially

loading each multiplexer’s 4-bit program latch (OA0:3) with the desired

input port address (IA0:3) and enabling the LOAD pin. When complete, the

CONFIGURE pin is strobed and all new configurations are simultaneously

transferred into the switch multiplexers. Data integrity is maintained on all

unchanged data paths.

• Low jitter and signal skew

• Fully differential data path

• Double-buffered

configuration latches

• 132-pin MQFP package

• Single +5V supply
