Microchip Technology, Inc. Telecom ZL50057GAG2

The ZL50057GAG2 is a 12,288-channel digital switch designed for telecom applications, featuring non-blocking unidirectional switching capabilities. It supports multiple configurations, including 12,288-channel x 12,288-channel switching, as well as various combinations of Backplane and Local input/output streams. The device can handle data rates of 2.048 Mbps, 4.096 Mbps, 8.192 Mbps, and 16.384 Mbps, with a maximum of 32.768 Mbps in fixed allocations. This switch offers exceptional input clock jitter tolerance, with a delay of 17 ns for data rates up to 16 Mbps and 14 ns for 32 Mbps. It includes features such as per-stream channel and bit delay, constant throughput delay for frame integrity, and high impedance output control. The ZL50057GAG2 is compatible with both ST-BUS and GCI-Bus operations and supports a non-multiplexed Motorola microprocessor interface for configuration and control. Applications for this device include central office switches, media gateways, access concentrators, and scalable TDM-based architectures. The ZL50057GAG2 is packaged in a 272-ball PBGA format, making it suitable for integration into various telecom systems.
