NXP Semiconductors TDA18274
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
