1. General description
The TDA18219HN supports all digital TV standards and delivers a LOW IF (LIF) signal to
a channel demodulator for digital TV. Standards that are covered include DVB-T/T2,
ISDB-T, DTMB, ATSC 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
