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
