SAA7154E; SAA7154H
Multistandard video decoder with comb filter, component
input and RGB output
Rev. 02 — 6 December 2007
Product data sheet
1. General description
The SAA7154E; SAA7154H is a high-quality multistandard video decoder supporting
10-bit Analog-to-Digital Converter (ADC), enhanced PAL/NTSC comb filtering, more
versatile Vertical Blanking Interval (VBI) data processing, high-definition component video
and picture improvement processing facilities.
It targets a variety of performance-conscious applications like e.g. Personal Video
Recording (PVR), Set-Top Boxes (STB), LCD projectors, LCD TVs and DVD recordable
players.

A video decoder decodes PAL/NTSC/SECAM signals into baseband component video.
This video decoder includes adaptive 2-dimensional luminance and chrominance
separation; in addition, e.g. baseband component type input signals can be connected
directly (RGB or Y-P
B
-P
R
, interlaced or progressive).

Multistandard video decoder with comb filter
The decoded video (the digitized component video, respectively) can be output on an 8-bit
or 10-bit wide
ITU-656
expansion port (X-port); alternatively decoded video can be fed to
a versatile video scaler to the Image port (I-port), which can be 8-bit, 16-bit or 24-bit wide.
An analog On-Screen Display (OSD) interface allows to mix OSD data on the I-port and
X-port video data; the digital OSD allows to add OSD data to the I-port video data.
