HXT5UZ1A
Ultra Slim TV Tuner for NTSC-US System
1. General Description
The Himax鈥檚 HXT5UZ1AS1 series tuner is designed in an
advanced single conversion RF architecture to implement a full
coil-free and alignment-free tuner.
IF demodulation use a video/sound split carrier and bandwidth
switchable SAW to reduce the interference between video and sound and excellent
sensitive for portable application
Thank to the coil-free design, the first SMD type tuners, the thinnest (3.0mm) and
smallest (volume: 2.4ml) size is successfully implemented.
2. Features
NTSC M/N system .
Compact size 2.4ml: 3.0mm(H)*37mm(L)*22mm(W)
Broadband freq range from 55.25 to 801.25MHz
High sensitivity for weak RF reception area
Output: Composite video, audio, 2nd sound IF, Analog AFT (Auto Frequency Tuning)
and S-curve voltage.
Synchronous video and audio demodulation.
Selectable wideband audio frequency response output (3dB@100KHz) for MTS
decoder or de-emphasized mono audio output
SIF output for further audio function application.
Both analog AFT S-curve voltage and readable AFT digital data output
