Product Summary

The STV0299BL is a CMOS single-chip multistandard demodulator for digital satellite broadcasting. The STV0299BL consists of two A/D converters for I-input and Q-input, a multistandard QPSK and BPSK demodulator, and a forward error correction (FEC) unit having both an inner(Viterbi) and outer (Reed-Solomon) decoder. The STV0299BL integrates a derotator before the Nyquist root filter, allowing a wide range of offset tracking. It is used in digital satellite receiver and set-top boxes.

Parametrics

STV0299BL absolute maximum ratings: (1)VDD_3.3 V Pad Power Supply Voltage: 4.0 V; (2)VDD Core Level Power Supply Voltage: 3.0 V; (3)VI Voltage on Input Pins: -0.5, VDD_3.3 V + 0.5 V; (4)VO Voltage on Output Pins: -0.5, VDD_3.3 V + 0.5 V; (5)Tstg Storage Temperature: -40, +150 ℃; (6)Toper Operating Ambient Temperature: -10, +70 ℃; (7)Tj Junction Temperature: +125 ℃.

Features
