DESCRIPTION
The THS7318 is a very low power single-supply 3
channel device designed to process Y’, P’_B, P’_R
enhanced definition TV and Y’, C’, and CVBS
standard definition TV signals. It integrates circuitry
to perform signal processing commonly required in
video output applications.
All channels incorporate 3^rd-order 20-MHz
Butterworth DAC reconstruction filters designed for
video systems with 54 MSPS DAC sampling rates
like NTSC/PAL 480p/576p EDTV and 480i/576i
SDTV video.
Rail-to-Rail output drivers on all channels allow for
both ac and dc coupled outputs.
The low quiescent current makes it an excellent
choice for USB powered or portable video
applications.
The THS7318 is available in a 9-pin NanoFree™
wafer scale package. It is specified for operation
from 0°C to 70°C.
