ZL50075
32 K Channel Digital Switch with High Jitter Tolerance, Rate Conversion per Group of 2 Streams (8, 16, 32 or 64 Mbps), and 64 input and 64 output Streams
Overview
| The ZL50075 is a fully featured 32 K TDM/TSI switch. The programmable (per group of 2 stream) rate selection at 8, 16, 32 or 64 Mbps with rate conversion allows interfacing peripheral components at different data rates. With exceptional jitter tolerance, the device directly uses clock signals from a backplane or a low cost digital PLL. It also provides G.711 (A-Law/µ-Law) code conversion and simultaneous BER testing on all streams. |
