Higher capacity for switching chips
Zarlink Semiconductor has announced immediate availability of the world's highest-capacity blocking and non-blocking TDM (time division multiplexing) switches
Offering the industry's most flexible TDM architecture, with four modes of switching, these off-the-shelf devices allow designers to cost-effectively process thousands of voice/data channels in multi-service, wide area network (WAN) access equipment. Service providers are continually introducing new voice, data, and video services that are driving demand for multiservice networking equipment with higher bandwidth and flexibility.

Time is right for Synchronous Ethernet
Integrated analogue/digital PLLs meet all Synchronous Ethernet timing requirements, including the latest recommendation from the ITU-T
Zarlink's new chips are optimised for use in high-bandwidth TDM switching equipment, including central office switches, digital loop carriers, mediation switches, access concentrators, media gateways and wireless basestation controllers.
Zarlink's novel four-in-one architecture boosts the performance and flexibility of TDM-based voice and data equipment, enabling high bandwidth, stream-to-stream switching, at any rate.
These devices offer a four-mode switching matrix: backplane to local, local to backplane, local to local, and backplane to backplane, at speeds ranging from 2 to 32Mbit/s.

The MT90868 high bandwidth switch (HBX) is the industry's highest density TDM blocking switch now in production.
The device provides timeslot interchange capacity of 32,768 channels x 8,192-channels between backplane and local streams, with access to 32K channels on the backplane, and datarates up to 32Mbit/s.
The MT90869 flexible 16k digital switch (F16kDX) is the industry's highest density TDM non-blocking switching device and is now available for sampling.
The device offers 16,384 channels x 16,384-channel unidirectional capacity, and also functions as a dual non-blocking switch with a capacity of 8,192 x 8,192 channels from backplane to local, and local to backplane streams.
The MT90869 is the industry's lowest power 16k x 16k switch, with typical consumption of only 576mW.
The MT90870 flexible 12k digital switch (F12kDX) is a flexible, high bandwidth TDM non-blocking switch offering 12,288 channels x 12,288 channels switching capacity.
The device can also be used as a blocking switch with a capacity of 8,192 channels x 4,096 channels.
The MT90868 is now in production, priced at US$210 in quantities of 1000 and packaged in a 466-ball plastic ball grid array (PBGA).
The MT90869 and MT90870 are now sampling.
The MT90869 sells for US$105 in 1k quantities and is housed in a 272-ball PBGA.
The MT90870 is priced at US$84 for 1k, and uses a 272-ball PBGA.
