ZL50073 32 K Channel Digital Switch with High Jitter Tolerance, Rate Conversion per Group of 4 Streams (8, 16, 32 or 64 Mbps), and 128 Input and 128 Output Streams
| Product Status - Production |
|
The ZL50073 is a fully featured 32 K TDM/TSI switch. The programmable (per group of 4 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 translation and simultaneous BER testing on all streams.
Features
- 32,768 channel x 32,768 channel non-blocking digital Time Division Multiplex (TDM) switch
- Per group (4 stream) data rate selection and rate conversion of 8.192, 16.384, 32.768 and 65.536 Mbps
- High jitter tolerance with multiple input clock sources and frequencies
- 128 serial TDM input streams, divided into 32 groups with 4 input streams per group
- 128 serial TDM output streams, divided into 32 groups with 4 output streams per group
- Flexible per stream input delay and output advancement allows stream alignment adjustment to compensate for bus delays
- Three sets of output timing signals for interfacing additional devices
- Per-channel A-Law/µ-Law Translation
- Per-channel constant or variable throughput delay for frame integrity and low latency applications
- Per-stream Bit Error Rate (BER) test circuits
- 16 bit non-multiplexed processor interface
- IEEE 1149.1 (JTAG) test port
- 3.3 V I/O with 5 V tolerant inputs; 1.8 V core voltage
Typical Applications
-
Multi-Service Switching Platforms (MSSPs)
- Media gateways
- Remote access concentrators
- Wireless base stations
- Class 4 and Class 5 Central Office switches
