General description
The TDA18219HN supports most digital TV standards and delivers a LOW IF (LIF) signal
to a channel demodulator for digital TV. Standards that are covered include DVB-T,
ISDB-T, DTMB and DVB-C.
The TDA18219HN facilitates design-ins by:
Allowing easy on-board integration
Drastically reducing the size of the tuner function
Providing flexibility in system solution development
2.
