描述 Description

The TDA18273HN is a high performance silicon tuner designed for terrestrial and cableTV reception for both analog and digital signals.
The TDA18273HN 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.
