ZL50020QCG1

Overview

The ZL50020QCG1 is a telecommunications interface integrated circuit functioning as a digital Time Division Multiplex (TDM) switch. It provides a 2048-channel by 2048-channel non-blocking switching matrix capable of operating at data rates of 8.192 Mbps and 16.384 Mbps, or utilizing mixed port speeds of 2.048, 4.096, 8.192, and 16.384 Mbps. The device features 32 serial TDM input streams and 32 serial TDM output streams, with outputs configurable for bidirectional backplane connections. It supports per-stream input and output data rate conversion and includes high-impedance control outputs for 16 streams.

Feature Summary

• Provides a large-scale non-blocking digital TDM switching fabric supporting multiple standard telecommunication data rates.
• Supports flexible per-stream data rate conversion allowing independent input and output speed configurations.
• Features exceptional input clock cycle-to-cycle variation tolerance to maintain signal integrity across varying conditions.
• Includes per-stream input bit delay capabilities with flexible sampling options for precise timing alignment.

Applications

• Telecommunications network infrastructure requiring high-density TDM switching
• Backplane interconnect systems in communication equipment
• Digital cross-connect systems for signal routing
