ZL70050
8 K Channel Digital Switch with High Jitter Tolerance, per Stream Rate Conversion (2, 4, 8, 16 or 32 Mbps), 32 Input and 32 Output Streams (Pin Compatible with MT90871)
Overview
| The ZL50050 is a fully featured TDM/TSI switch. The programmable per stream rate selection at 2, 4, 8, 16 or 32 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. |
