TDA18219HN

Silicon tuner for terrestrial and cable digital TV reception

Rev. 6 — 13 July 2012

Product short data sheet

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

2. Features and benefits

 Fully integrated IF selectivity; eliminating the need for external SAW filters

 Fully integrated oscillators

 Alignment free

 Single 3.3 V supply voltage

 LOW power consumption

 Integrated wideband gain control

 Crystal oscillator output buffer (16 MHz) for single crystal applications

 I²C-bus interface compatible with 3.3 V microcontrollers

 Easy programming

 5 ms tuning time

 LIF channel center frequency output ranging from 3 MHz to 5 MHz

 1.7 MHz, 6 MHz, 7 MHz, 8 MHz and 10 MHz channel bandwidths

 Loop-Through (LT)

 RoHS compliant
