8.10.7 Reference Voltage Generating Circuit
and Comparator
The composite video signal clamped by the clamping circuit is input
to the reference voltage generating circuit and the comparator.
(1) Reference voltage generating circuit
This circuit generates a reference voltage (slice voltage) by us-
ing the amplitude of the clock run-in pulse in line specified by the
data slice line specification circuit. Connect a capacitor between
the V
HOLD
pin and the V
SS
pin, and make the length of wiring as
short as possible so that a leakage current may not be gener-
ated.
(2) Comparator
The comparator compares the voltage of the composite video
signal with the voltage (reference voltage) generated in the refer-
ence voltage generating circuit, and converts the composite video
signal into a digital value.
Fig. 8.10.10 Clock Run-in Detect Register
8.10.8 Start Bit Detecting Circuit
This circuit detects a start bit at line decided in the data slice line
specification circuit.
The detection of a start bit is described below.
A sampling clock is generated by dividing the reference clock out-
put by the timing signal.
A clock run-in pulse is detected by the sampling clock.
After detection of the pulse, a start bit pattern is detected from the
comparator output.
8.10.9 Clock Run-in Determination Circuit
This circuit determinates clock run-in by counting the number of pulses
in a window of the composite video signal.
The reference clock count value in one pulse cycle is stored in bits 3
to 7 of the clock run-in detect register (address 00E4
16
). Read out
these bits after the occurrence of a data slicer interrupt (refer to
“8.10.12 Interrupt Request Generating Circuit”).
Figure 8.10.10 shows the structure of clock run-in detect register.
