Chip manages voice, data and video traffic

A new WAN access switching chip announced by Mitel Semiconductor, a division of Mitel Corp., delivers high channel capacity to converged networks.

The MT90866 switches up to 4,096 by 2,432 channels. It also manages voice, data and video traffic in large scale carrier-class equipment that bridges information on packet-based data networks to the circuit-switched public telephone network.

The chip incorporates a phase locked loop, a block of circuitry that minimizes the effects of converging different types of switch-based traffic on the network by optimizing system timing and synchronization.

The MT90866 is a three-volt time division and multiplex timeslot interface. The device incorporates three switching functions into a single product – 4,096 by 2,432 channels between backplane and the local streams, 2,432 by 2,432 channels among local streams and 2,048 by 2,048 channels among backplane streams.

The MT90866 ( is priced at US$60 in quantities of 10,000.
