TDA18214
Silicon tuner for digital terrestrial and cable TV reception
Rev. 1 — 13 July 2012
Preliminary short data sheet
1. General description
The TDA18214AHN and TDA18214HN are high performance silicon tuners designed for
digital terrestrial and digital cable TV reception.
The TDA18214AHN and TDA18214HN support all digital TV standards and deliver a Low
IF (LIF) signal to a demodulator.
The TDA18214AHN and TDA18214HN facilitate STB design by:
Allowing on-board integration
Drastically reducing the tuner Bill Of Material (BOM)
Providing flexibility in system solution development
Allowing straightforward, cost effective dual and multi-tuner applications optimization
In multi-tuner application, the TDA18214AHN is the master tuner whereas the
TDA18214HN is a slave tuner.
2. Features and benefits
Single 3.3 V supply voltage
Worldwide multistandard digital terrestrial and digital cable capabilities
Alignment free
RoHS compliant
I2C-bus interface compatible with 3.3 V microcontrollers
Crystal oscillator output buffer
Slave Tuner Output (STO) for multi-tuner applications (TDA18214AHN only)
Fully integrated oscillators
2 programmable General-Purpose Outputs (GPO)
Loop-Through Output (LTO)
1.7 MHz, 6 MHz, 7 MHz, 8 MHz and 10 MHz channel bandwidths
LIF channel center frequency output ranging from 0.8 MHz to 7.5 MHz
Fully integrated IF selectivity; eliminating the need for external SAW filters
Large flexibility in the IF filtering stage to ease the matching with various demodulators
circuits
Single-ended RF input, no need for external balun
Up to 1 GHz RF input capability
Excellent return loss compatible with cable requirements
Power Level Detector (PLD) embedded
Integrated gain control
