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

C-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

The maximum allowed ambient temperature T
amb(max)
depends on the assembly conditions of the package and especially on the design
of the Printed-Circuit Board (PCB) and die connection. The application mounting must be done in such a way that the maximum junction
temperature is never exceeded. The junction temperature can be obtained by reading the temperature sensor bit via I
