ZL50031
Flexible 4 K x 2 K Channel Digital Switch with H.110 Interface with 2 K x 2K Local switching
Overview
The ZL50031 Digital Switch provides switching capacities of 4 K x 2 K channels between backplane and local streams, 2 K x 2 K channels among local streams and 2 K x 2 K channels among backplane streams. The Local streams have 32, 64 and 128 64 kbps channels per frame with data rates of 2.048, 4.096 and 8.192 Mbps respectively. The bi-directional backplane streams have 128 and 256 64 kbps channels per frame with data rates of 8.192 and 16.384 Mbps respectively. The ZL50031 is intended for carrier-grade applications that require high bandwidth switching capability. With compliance to the ECTF H.110 specification, it is also suitable for using a compact PCI platform. The device has features that are programmable on per-stream or per-channel basis including message mode, input delay offset, output advancement offset, direction control and high impedance output control. |
