Zarlink new high-density TDM devices

In Electronic Infomation Category: R | on November   1, 2010

Zarlink Semiconductor Inc. (Zarlink Semiconductor) has introduced the industrys most comprehensive characteristics of TDM / TSI switching products, for the design of an integrated network for the next generation of wireless network equipment and LT1613CS5 datasheet and high-density switch established new performance standards.

Zarlink developed 32K ZL ? 50073 TDM switching products to meet the high bandwidth wired and LT1613CS5 price and wireless network equipment stringent technical requirements, these devices used to transmit integrated voice, data and LT1613CS5 suppliers and multimedia services, such as media gateways, wireless base stations and remote access concentrators and so on. Level 4 / Level 5 central office converter is still today the leading telecommunications network, customers need higher performance upgrade their TDM devices. Zarlinks ZL50073

series composed of four devices for high-bandwidth voice and data equipment provides the industrys most flexible and cost-effective central exchange programs. ZL50073 is the main switching device in the series, it makes the device competitive ability to increase high-density has doubled and the interface for peripheral devices 128 and 128 output stream input streams, while also providing up to 64 Mb / s different data rates.

ZL50073 series, with its unmatched integration features, and promote a high-bandwidth TDM equipment performance, and board-level design while reducing the cost and complexity. The devices include programmable data rate conversion circuit, allowing them to directly transfer information between peripheral devices, without intermediate FPGA (field programmable gate array), the connection logic or other circuit board complexity and increase the cost of the external circuit.

ZL50073 family includes 32K TDM device, which is only a per-channel integrated A-law / m law conversion circuit, eliminating the standard in voice conversion between the external demand for FPGA logic device or connection. The device also integrates a BER (Bit Error Rate) test circuit, the circuit meets ITU-T (International Telecommunication Union Telecommunication Commission) O.151 standards, and has a separate receiver and transmitter. In this way, designers can simultaneously test all input stream / output stream; and competing devices require external test equipment, and can only test a channel, time-consuming amazing.

ZL50073 TDM switch family has excellent jitter tolerance, allowing direct from the floor to the exchange of clock and frame pulse clock, avoiding the intermediate chips such as CPLD (complex programmable logic devices) and FPGA requirements, saving the cost and work.

High jitter tolerance means that when the need to refer to an exchange or failure to maintain function, the designer can choose the number of economic PLL (phase locked loop). ZL50073 device provides three clock input, selectable receive frequency of 8,16,32 or 64 MHz. High-density TDM devices other business the way only 32 MHz clock input, severely limits the designers to select the range of the device clock.

In addition, Zarlinks TDM switching device is the industrys only optional with the four-frequency output clock and frame pulse of high-density device driver for the designers of various peripheral devices or circuits TDM flexibility.

Zarlinks high-density TDM switching family includes three 32,768-channel devices and a 24,576-channel devices, the industrys only 24K switches. A variety of device options can help designers to select cost-effective features and to meet their needs.

ZL50073 switching device 32K is the worlds most advanced devices. ZL50074 device is also a 32K switch devices, but its characteristics are optimized for price-sensitive applications. ZL50073/74 offer 128 and 128 output stream input streams. The ZL50075 device

32K exchange 64 with 64 input streams and output streams, integrated A-law / m law conversion circuit and the BER test circuit, with each data stream of the industrys second highest rate of conversion size. ZL50070 switching devices are feature-rich devices 24K, 96 input and 96 output stream stream.

Zarlink will continue to improve its TDM switching product line. Future development will provide low and high density devices to improve system-level integration.

ZL50073 series now in volume production, and provides a variety of sizes and packaging options. All prices are one thousand unit quantities when.
