TDA18274

TDA18274 Hybrid (analog and digital) silicon tuner for terrestrial and cable TV reception Rev. 1 — 11 February 2013 Product short data sheet 1. General description The TDA18274 is a high performance silicon tuner designed for terrestrial and cable TV reception for both analog and digital signals. The TDA18274 supports all analog and digital TV standards and delivers a Low IF (LIF) signal to a demodulator for analog TV and/or a channel demodulator for digital TV. The TDA18274 facilitates TV design by: Allowing on-board integration Drastically reducing the tuner Bill Of Material (BOM) Providing flexibility in system solution development Allowing straightforward and cost effective multi-tuner applications optimization 2. Features and benefits  Single 3.3 V supply voltage  Worldwide multistandard terrestrial and cable capabilities  Alignment free  RoHS compliant  I2C-bus interface compatible with 3.3 V microcontrollers  Crystal oscillator output buffer as well as Slave Tuner Output (STO) for multiple tuner applications  Fully integrated oscillators  Fully integrated RF selectivity (no need for RF tracking filters coils) (TDA18274HD only)  2 programmable General-Purpose Outputs (GPO)  1.7 MHz, 6 MHz, 7 MHz, 8 MHz and 10 MHz channel bandwidths  LIF channel center frequency output ranging from 0.8 MHz to 7.5 MHz  Fully integrated IF selectivity; eliminating the need for external SAW filters  Large flexibility in the IF filtering stage to ease the matching wi...
