TDK Semiconductor Introduces New Line Interface Transceiver IC for E3, DS3, STS-1, and ATM Applications; Offers 3.3 V or 5 V Operation Capability.

TUSTIN, Calif.--(BUSINESS WIRE)--May 4, 1998--TDK Semiconductor Corp., a leader in the design and manufacture of communication semiconductors for worldwide markets, is introducing its newest line interface transceiver IC for E3, DS3, STS-1 and ATM applications. The device, designated the 78P2241, operates at both 3.3 V and 5 V power supply voltages.

The 78P2241 is a single-chip IC which features a clock recovery and transmitter pulse shaping function for applications using 75-ohm coaxial cable at distances up to 1100 feet. The receiver recovers clock and data from a B3ZS or HDB3 coded AMI signal. It can compensate for over 12dB of cable loss.

According to Kirk Brinkworth, TDK Semiconductor's director of marketing: "This new device, which is being manufactured in an advanced BiCMOS process, gives the designer the flexibility of 5 V or 3.3 V, with lower power consumption. The primary product applications include digital multiplexers, SONET Add/Drop multiplexers, PDH equipment, DS3 to fiber optic and microwave modems and ATM/WAN access for routers and switches."

The 78P2241 is pin and functionally compatible to TDK Semiconductor's 78P7200. It adds a B3ZS/HDB3 ENDEC, loop-back and clock polarity selection as well as ability to receive a DSX monitor signal. The 78P2241 is available off-the-shelf for $33.00 at volumes of 1,000 pieces.
