16x16 Digital ECL
Crosspoint Switch
The TQ8015 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 ECL I/O, the TQ8015 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 TQ8015 is ideally suited for digital video, data
communications and telecommunication switching applications.
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.
