VSP 94x5B, VSP 94x7B
Color Decoder and Scan-Rate Converter
Release Note: Revision bars indicate significant
changes to the previous edition. The hardware and
software description in this document is valid for
the VSP 94x5B/VSP 94x7B version Cx.
1. Introduction
The VSPB family supports 15/32 kHz systems and is
available with different options. VSP 94xxB has one
channel only. VSP 94x5B supports two channels,
including PiP, double-window etc. The VSP 942xB ver-
sions come in a MQFP144 package, whereas all other
versions come in a MQFP80 package, pin compatible
to other VSP 94xx devices (e.g. VSP 94x2A). The
VSP 943xB and VSP 944xB come without scan-rate-
converter and a single-scan (50i/60i) signal is output.
Table 1–1 and Table 1–2 give an overview of the VSPB
single-chip family.

2.3.1. Double CVBS Frontend
The CVBS and Y/C decoding is done by two CVBS-
frontends working in parallel. Normally, the comb-filter
is connected to the first frontend, giving the main pic-
ture whereas the second frontend generates an
uncombed picture for the PiP channel.
The input of frontend 1 is selected by COMBUSEM,
the input for frontend 2 is selected by COMBUSES
(refer to Figure 2–1).
As two CVBS-ADC are not sufficient for any combina-
tion of input signals, RGB-ADCs can be used as well
for CVBS, Y/C conversion. When using these ADCs,
the signal must be switched/connected on the PCB
accordingly.
At least two solutions are possible:
– When using Y/C for main channel, PiP channel can
be connected to G_ADC. An external device must
be used to switch one CVBS output and the G-sig-
nal to GIN1. If only one RGB/YUV input is required,
one CVBS out can be directly connected to GIN2.
– When two Y/C inputs are required, Y1 and Y2 can
be connected to CVBSIN4 and CVBSIN6, C1 and
C2 can be connected to RIN1 and RIN2 (please
refer to "Source Select" on page 20).To make use of
the ’Y/C to CVBS adder’, C1 and C2 should be addi-
tionally connected to CVBSIN5 and CVBSIN7.
