General description

The TDA18250 is a silicon tuner IC designed specifically for high definition cable Set-Top

Boxes (STB) supporting single streaming.

Used in conjunction with a digital channel demodulator, the TDA18250 covers all

worldwide digital cable standards.

• The TDA18250 ensures a low system cost as:

– Costly components such as low-noise amplifiers, Surface Acoustic Wave (SAW)

filters are eliminated from the system BOM

• The TDA18250 high-performance silicon tuner meets today’s digital cable TV

reception needs with:

– Low power consumption

– High linearity

– Low noise figure

• The TDA18250 ensures ease of use with:

– Easy on-board integration

– Efficient and effective PCB design

– Reduced external components

Features and benefits

 RF frequency coverage up to 1002 MHz

 Integrated wideband gain control

 LOW IF (LIF) output

 Single 3.3 V power supply

 Low power consumption

 Multistandard cable receptions

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

 RF Loop-Through (LT)

 Enhanced RF and IF filters to increase selectivity and adjacent channels filtering

 Alignment free

 Fully integrated oscillators:

 No external oscillator components for reduced cost

 16 MHz crystal oscillator output buffer for single crystal applications

 Supports 2 tuner functions specifically aimed for PVR boxes:

 1  RF output to drive slave tuner

 I2C-bus provides:

 3.3 V microcontroller compatibility

 Received Signal Strength Indicator (RSSI) data access

 Die temperature sensor data access

 Lead-free (Pb) manufacturing
