General description
The SAA7115 is a video capture device for applications ranging from small screen
products such as digital set-top boxes and personal video recording applications to
large screen devices like LCD projectors that benefit from its improved comb filter
performance and 10-bit video output capabilities.
It combines a two channel analog pre-processing circuit and a high performance
scaler. The pre-processing circuit includes source selection, an anti-aliasing filter and
an analog to digital converter, an automatic clamp and gain control, two clock
generation circuits and a digital multi-standard decoder containing two-dimensional
chrominance/luminance separation using an improved adaptive comb filter. The high
performance scaler features variable horizontal and vertical up and down scaling and
a Brightness Contrast Saturation (BCS) control circuit. Based on the principle of line-
locked clock decoding, the decoder is able to decode PAL, SECAM and NTSC
signals into ITU-601 compatible colour component values.
It accepts CVBS or S-Video (Y-C) analog inputs from TV or VCR sources, including
weak and distorted signals. The expansion port (X-port) for digital video (bi-
directional half duplex, D1 compatible) can be used either to output unscaled video
using 10-bit or 8-bit dithered resolution or to connect to other external digital video
sources for reuse of the SAA7115's scaler features. An enhanced image port (I-port)
supports 8(16)-bit wide output data with auxiliary reference data for interfacing to
VGA controllers, set-top box applications, etc. It is also possible to output video in

Square Pixel formats accompanied by a square pixel clock of the appropriate
frequency.
The SAA7115 can capture the serially coded data in the vertical blanking interval
(VBI-data) of several broadcast standards. It also incorporates also a frame locked
audio clock generation. This ensures that there is always the same number of audio
samples associated with a frame or set of fields. This prevents the loss of
synchronisation between video and audio, during capture or playback. Furthermore
the second analog onboard PLL optionally can be used to enhance this audio clock to
a low jitter frame locked audio clock. All the functions of the SAA7115 can be
controlled via I²C-bus.
