Microsemi / Microchip Schalt-ICs

Switch Types

Microsemi / Microchip MT88xx Analog Cross-Point Switches are fabricated in ISO-CMOS technology providing low-power dissipation and high reliability. They contain an array of crosspoint switches along with line decoder and latch circuits. Any one of the 32, 64, 96 or 128 switches can be addressed by selecting the appropriate address bits. The selected switch can be turned on or off by applying a logical one or zero to the DATA input.​

Microsemi / Microchip MT8920 ST-BUS Parallel Access Circuit (STPA) provides a simple interface between ST-BUS and parallel system environments. The MT90812 provides non-blocking time slot interchange capability for B, C and D channels, up to a maximum of 192 channels. It offers conference call capability for 15 parties over a maximum of 5 conference bridges. 

​Microsemi / Microchip MT89xx 128 to 4k switches are designed for switching PCM-encoded voice or data, under microprocessor control, in a modern digital exchange, PBX or Central Office. They provide simultaneous connections for up to 256 64kbps channels. Each of the eight serial inputs and outputs consist of 32 64kbps channels multiplexed to form a 2048kbps ST-BUS stream.

Microsemi / Microchip ZL5001x TDM/TSI Switches are non-blocking TDM switches with 512x512 channels, switching capacities, and integrated Stratum 4 or 4E DPLL. They are designed for low density applications such as small and medium size multi-service access platforms, remote access servers, and IP-PBX. 

Microsemi / Microchip ZL50031 Digital Switch provides switching capacities of 4K x 2K channels between backplane and local streams, 2K x 2K channels among local streams and 2K x 2K channels among backplane streams. The Local streams have 32, 64 and 128 64kbps channels per frame with data rates of 2.048, 4.096 and 8.192Mbps respectively.
