TDA18250HN

The TDA18250HN is designed as one kind of single-chip direct conversion Silicon Tuner IC device that can be used for high definition cable Set Top Boxes (STB) supporting single streaming.

Features of the TDA18250HN are:(1)RF frequency coverage up to 860 MHz; (2)Integrated wideband gain control; (3)LOW IF (LIF) output; (4)Single 3.3 V power supply; (5)Low power consumption; (6)Multistandard cable receptions; (7)Fully integrated IF selectivity, eliminating the need for external SAW filters; (8)RF Loop-Through (LT); (9)Enhanced RF and IF filters to increase selectivity and adjacent channels filtering; (10)Alignment free; (11)Fully integrated oscillators:; (12)No external oscillator components for reduced cost; (13)16 MHz crystal oscillator output buffer for single crystal applications.

The absolute maximum ratings of the TDA18250HN can be summarized as:(1)supply voltage: -0.3 to +3.60 V;(2)input voltage: -0.3 to VCC+0.3 V;(3)storage temperature: -40 to +150 ;(4)junction temperature: 115 ;(5)electrostatic discharge voltage: 2 kV or 21.5 kV.
