1 / 4 page Semiconductors TDA827x Silicon Tuner Family Based on a revolutionary concept, the TDA827x silicon tuner family frees manufacturers from many of the constraints of traditional RF design. This comprehensive silicon tuner family for cable modem, digital STB and analog PC-TV reception offers the necessary selectivity for all targeted applications. The TDA827x silicon tuner family offers a very simple tuner solution for cable modem, digital STB and analog PC-TV reception, enabling incredible simplifications in TV design. Its patented technology and highly innovative architecture reduces external component count, providing an extremely cost effective silicon tuner that is easier and quicker to design in than any other comparable solution in today’s market. A giant leap forward in RF integration, the TDA827x features an embedded low noise input amplifier and an image rejection mixer for processing RF signals and downconverting to low IF signals, which are then filtered before being sent to the channel decoder or IF demodulator. It offers optimal partitioning of functions at the system level, removing the need for both SAW filters or IF amplifiers. This family also features a fully integrated VCO that has no external tank component, an RF splitter with two separate outputs and an RSSI signal indicator embedded on the IC.All this integration results in very low power consumption for the TDA827x, removing the need for an external heat sink and further simplifying design-in efforts. A complete family The TDA827x family is a complete range of silicon tuners, featuring dedicated devices for a wide range of applications: • TDA8270HN: US STB or cable modem applications • TDA8271HN: Rest of the world STB and cable modem applications • TDA8274HN: Multi standard STB and cable modem applications* • TDA8275HN:Terrestrial analog reception for PC-TV application * This version allows the STB or cable modem manufacturer to build a multi-standard platform able to address the global market. Applications • DOCSIS and EuroDOCSIS cable modems • Digital Set Top Boxes • Analog TV reception on PCs Common features • Real Silicon tuner approach: only 30 SMD components for the Bill of Material (BOM) • Wideband low noise RF amplifier with AGC • Integrated and Programmable Selectivity • RF splitter with 2 separate outputs (-2 / +6 dB) • RF filter • Image rejection mixer stage • Fully integrated VCO • RSSI signal indicator, +/- 0.5 dB relative accuracy (3 dB absolute value), no calibration needed • Integrated 16 MHz crystal oscillator and output buffer to channel decoder or other tuner • I²C bus controlled • Temperature range: -20 to + 70°C • Power: 3.3V, 1.29 W (typical) • Package: MLF 40 pins 6 x 6 mm HVQFN40 |
