AGC/video amplifier IC improves performance of digital set-top boxes, cable modems

Santa Clara, Calif. — NEC introduced a silicon monolithic IC designed for use as an AGC amplifier for digital CATV, cable modem and digital terrestrial systems. The µPC3231GV combines a 30-90 MHz AGC amplifier with an on-chip video amplifier that provides output for both ODFM modulators and QPSK/QAM data transmission. High gain and 61 dB of gain control range allows the µPC3231GV to handle a wide range of input signals, while low-noise and low distortion ensure the delivery of a clean signal. Typical performance specifications include a high gain of 65 dB, a wide control range of 61 dB, low noise of 5 dB, distortion of 53 dBc, IM₃ at -20 dBm PIN, and operates from a supply voltage of 5 V. The µPC3231GV is housed in NEC's 8-pin plastic surface mount SSOP "GV" package. It measures 2.9 x 4.9-mm and is RoHS-compliant.
