Level One Meets Next Level of Standards For T1/E1 Quad Receiver.

SACRAMENTO, Calif.--(BUSINESS WIRE)--Sept. 22, 1998--Level One Communications, Inc. (Nasdaq:LEVL), today announces volume production of the LXT336QE, a next generation, fully integrated, four channel, T1/E1 pulse code modulation (PCM) receiver.

The device, meeting ITU's G.775 and ANSI's T1.231, sets a new level of standards compliance for multi-port receivers. This is the only quad receiver on the market to meet loss-of-signal detection standards. The LXT336 was designed to enhance the performance of transport, interface, and line monitoring equipment applications.

Ideal for the growing E1 market in Europe and Asia, the LXT336 has been enhanced with a high performance differential receiver, unipolar or bipolar mode PCM interface, and RZ data recovery mode. The receiver architecture has a high noise interference margin and is capable of recovering data as low as 500 mV and up to 12 dB cable attenuation. This feature allows equipment designers to overcome poor line conditions without adding additional cost for line conditioning.

Interface to the back-end processor is made easier through a switchable unipolar and bipolar PCM interface. In unipolar mode, the AMI and HDB3 decoders enable in-service code violation monitoring and reduce circuitry requirements in the framer or ASIC.

The available on-board RZ data recovery mode reduces the need for adding external clock circuitry, thereby reducing system design cost. The device easily interfaces to custom ASICs with embedded clock recovery circuitry allowing seamless integration and time-to-market advantages.

The LXT336 operates over a temperature range of -40 Degrees to +85 Degrees C. The device, in 64-pin QFP packaging, is currently in volume production and in volumes of 10K units is priced at $12.97.
