PTVP9900 Integrated Circuit Chip VSB/QAM Receiver

Introduction

The TVP9900 is a cost-effective digital TV (DTV) front-end IC targeted for low-cost high-volume DTV receivers. The TVP9900 is a system-on-chip (SoC) device that integrates the main functions of a DTV front-end system, including programmable gain amplifier (PGA), A/D converter, VSB demodulator, ATSC forward error correction (FEC), QAM demodulator, and ITU-T Annex B FEC. It provides rich peripheral support including AGC control, tuner control, CEA-909 antenna control, and host I 2C interface. The TVP9900 supports processing of ATSC VSB or ITU-T Annex B QAM IF inputs.
