TDA18273HN

Hybrid (analog and digital) Silicon Tuner for terrestrial and

cable TV reception

Rev. 3 — 10 May 2011

Product short data sheet

1. General description

The TDA18273HN is a high performance Silicon Tuner designed for terrestrial and cable

TV 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.

2. Features and benefits

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

Worldwide multistandard terrestrial and cable

Fully integrated oscillators

Alignment free

Single 3.3 V supply voltage

Power level detector

Integrated wideband gain control

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

I²C-bus interface compatible with 3.3 V microcontrollers

Self AGC synchronization mode (VSYNC)

Very fast 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

Ready for DVB-T2 and DVB-C2

RoHS compliant

Strong immunity to spurious and field interferences
