New Line Interface Transceiver IC for E3, DS3 and STS-1 Applications From TDK Semiconductor; Adds Line-Code Violation Detector.Business Editors & High Tech Writers TUSTIN, Calif.--(BUSINESS WIRE)--Jan. 15, 2001 TDK TDK Türk Dil Kurumu (Turkish Language Council) TDK The Dark Knights (gaming clan) TDK Tokyo Denkikagaku Kogyo KK (TDK Electronics Co. Ltd. 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 and STS-1 applications. The device operates at both 3.3V and 5V power supply voltages. It consumes less than 110 mA (max.) of supply current. Designated the 78P2241B, the single chip IC adds a line-code violation (LCV) detector to the feature set first available with the 78P2241, released in 1999. Other features include a clock recovery and transmitter pulse shaping function for applications using 75-ohm coaxial cable at distances up to 1,100 feet and speeds up to 51.84 Mbps. The receiver recovers clock and data from a B3ZS B3ZS Bipolar Three Zero Substitution or HDB3 coded AMI signal. It can compensate for over 12dB of cable and 6dB of flat loss. The transmitter generates a signal that meets the ANSI (American National Standards Institute, New York, www.ansi.org) A membership organization founded in 1918 that coordinates the development of U.S. voluntary national standards in both the private and public sectors. It is the U.S. member body to ISO and IEC. T1.102-1993 and ITU-T See ITU. ITU-T - International Telecommunications Union G.703 pulse shape specifications. According to Andy Mills, vice president and general manager of the company's Network business unit at TDK Semiconductor: "This new addition to our growing family of transceivers, manufactured in BiCMOS, adds new functionality to our already popular DS3/E3 LUIs. This LCV detector functionality is in demand for many applications, with the strongest interest coming from video over DS3 applications. Other product applications include DSLAMs, digital multiplexers, SONET Add/Drop multiplexers, PDH equipment, DS3 to fiber optic and microwave modems and ATM/WAN access for routers and switches." The 78P2241B is pin and functionally compatible to TDK Semiconductor's 78P2241, 78P7200L and 78P7200. To the 78P7200, it adds a B3ZS/HDB3 ENDEC, loop-back and clock polarity selection as well as ability to receive a DSX3 monitor signal. The 78P2241B is available in 28-lead PLCC (Plastic Leaded Chip Carrier) A plastic, square, surface mount chip package that contains leads on all four sides. The leads (pins) extend down and back under and into tiny indentations in the housing. See chip package. or 48-lead TQFP See QFP. packages, each of which is priced at $31.00 in 10,000 unit quantities. Samples are currently available, with production planned for March 2001.
