HXT5UZ1A
Ultra Slim TV Tuner for NTSC-US System
1. General Description
The Himax’s 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.
