ZL50057/8
12 K-Channel Digital Switch with High Jitter
Tolerance, Per Stream Rate Conversion (2, 4, 8,
16, or 32 Mbps), and 48 Inputs and 48 Outputs
Data Sheet
Features
• 12,288-channel x 12,288-channel non-blocking
unidirectional switching.The Backplane and Local
inputs and outputs can be combined to form a
non-blocking switching matrix with 48 input
streams and 48 output streams
• 8,192-channel x 4,096-channel non-blocking
Backplane input to Local output stream switch
• 4,096-channel x 8,192-channel non-blocking
Local input to Backplane output stream switch
• 8,192-channel x 8,192-channel non-blocking
Backplane input to Backplane output switch
• 4,096-channel x 4,096-channel non-blocking
Local input to Local output stream switch
• Rate conversion on all data paths, Backplane-to-
Local, Local-to-Backplane, Backplane-to-
Backplane and Local-to-Local streams
• Backplane port accepts 32 input and 32 output
ST-BUS streams with data rates of 2.048 Mbps,
4.096 Mbps, 8.192 Mbps or 16.384 Mbps in any
combination, or a fixed allocation of 16 input and
16 output streams at 32.768 Mbps
• Local port accepts 16 input and 16 output ST-
BUS streams with data rates of 2.048 Mbps,

4.096 Mbps, 8.192 Mbps or 16.384 Mbps in any
combination, or a fixed allocation of 8 input and 8
output streams at 32.768 Mbps
• Exceptional input clock jitter tolerance (17 ns for
16 Mbps or lower data rates, 14 ns for 32 Mbps)
• Per-stream channel and bit delay for Local and
Backplane input streams
• Per-stream advancement for Local and
Backplane output streams
• Constant 2-frame throughput delay for frame
integrity
• Per-channel high impedance output control for
Local and Backplane streams
• Per-channel driven-high output control for Local
and Backplane streams
