TDA18254AHN

The TDA18254AHN is designed as one kind of Silicon tuner IC device that specifically for high definition multi-tuner cable Set Top Boxes (STB) supporting single streaming and multi-streaming PVR STBs with watch, record, video-on-demand and in-home video distribution capability.

Features of the TDA18254AHN are:(1)Integrated wideband gain control; (2)Extended frequency coverage up to 1002 MHz; (3)Integrated RF tracking filters for rejection of unwanted signals; (4)Single 3.3 V power supply; (5)Low power consumption; (6)Multistandard cable receptions; (7)Enhanced RF and IF filters to increase selectivity and adjacent channels filtering; (8)RF loop-through; (9)Fully integrated IF selectivity, eliminating the need for external SAW filters; (10)Alignment free; (11)Lead-free (Pb) manufacturing; (12)Die temperature sensor data access.

The absolute maximum ratings of the TDA18254AHN 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: 105 ;(5)electrostatic discharge voltage: 1.5 or 2 KV.
