TQ8016

The TQ8016 is a 16 x 16 differential digital crosspoint switch capable of

handling 1.3 Gbit/s data rate. The high data rate and exceptional signal

fidelity is made possible with TriQuint's fully differential Source-Coupled

FET Logic (SCFL) standard cells. The symmetrical switching characteristic

inherent in differential logic results in low signal skew and crosstalk for

maximum signal fidelity.

Features

• >1.3 Gigabit/sec data rate

• Non-blocking architecture

The user can independently configure any switch output to any input,

including an input chosen by another output. To configure the switch, the

4-bit output address (OA0..3) is decoded to enable the loading of the 4-bit

input selection data (IA0..3) on the rising edge of the LOAD signal. The

process is repeated until all desired connections are programmed. By

bringing the CONFIGURE signal high, the contents of the Output Select

Latches are transferred in parallel to a second row of 4-bit latches (R2),

causing the switch reconfiguration.

• +200 ps delay match (one

input to all outputs)

•

ECL-level data inputs/outputs;

CMOS-level control inputs

• Low crosstalk

• Fully differential data path

• Double row of output select

latches minimizes

reconfiguration time

This double row architecture minimizes the time to completely reconfigure

the switch since a new set of addresses can be loaded to the Output Select

Latches (R1) while the switch is active (transmitting). At the time of

reconfiguration, no data drop-out occurs for any output whose input

connection does not change.

• Available in 132-pin leaded

chip carrier

For applications which do not require synchronous configuration of the

switch, the LOAD and CONFIGURE inputs may be tied together.
