Functional Description
The 5303B is an analog A/V interface IC designed for
TV and general-purpose A/V applications. The device
accepts up to three sets of SCART input signals (Red,
Green, Blue, CVBS, R, L, Fast Blanking, and TV
Function). By way of 3:1 mux, SCART 1, 2, or 3 signals
can be selected at the device’s output pins. The 5303B
supports four SCART video modes: RGB/CVBS, RGB-
only, CVBS-only and SVHS. The RGB and CVBS video
driver gains are programmable from 2 to 1.4 in 0.2
steps, and the R/L audio driver gain can be 0dB or 6dB.
The R/L audio drivers can accept signals from 0.5Vrms
to 2Vrms.
For general-purpose A/V applications, video switches
and drivers can be configured to support component
video (YPrPb), S-Video (SVHS), and composite video
(CVBS) signals.
All switching and programmable functions of the
device are controlled through a standard I
2C serial
interface
DC Restore for RGB, Y, and CVBS: The device will
generate a DC restore level on each video output based
on timing referenced to a horizontal sync pulse. When
the sync pulse is detected, the DC restore circuit will act
to position the blank level to 1.2V at the respective RGB,
Y, or CVBS output pin(s).
DC Restore for SVHS and YPrPb: In the SVHS
mode, the CVBS pin is used as Luma input and the
Red pin is used as Chroma input. The DC restore
function for Luma signal is equivalent to CVBS signal.
The DC restore circuit will position the output blank level
to 1.2V at the respective Luma output pin. For the
Chroma input, the on-chip clamp circuit will be used to
position the output mid-scale DC level to 1.8V. In the
YPrPb mode, the mid-scale DC level for Pr and Pb
outputs will also be at 1.8V.
A/V Input Source Selection
The device accepts up to three sets of A/V input
signals. Bits 0 & 1 of Register 0 determine which of the
sets will be present at the device’s output pins.
Video Mode Selection
The device supports four video modes for TV SCART
applications: RGB/CVBS, RGB-only, CVBS-only, and
SVHS. Bits 2, 3, & 4 set the active video mode.
RGB/CVBS video mode is a default mode. For general-
purpose A/V applications, the device supports
YPrPb/CVBS and CVBS/SVHS video modes.
RGB Gain
The gain of the RGB outputs can be adjusted to one of
four different levels. Bits 0 & 1 Register 1 set the gain
of the RGB output amplifiers according to the following
table:
Bit 1

four different levels. Bits 2 & 3 Register 1 set the gain
of the CVBS output amplifier according to the following
table:

0dB or 6dB. Bit 4 of Register 1 sets the gain of the
amplifiers according to the following table:
