Video switch for CANAL-Plus decoder
BA7630S / BA7630F
The BA7630S and BA7630F are decoder switching ICs for the scrambled broadcasts in France. The ICs include a 3-
input multiplexer, 2-input multiplexers with 6dB amplifiers, and a 9-bit serial-to-parallel converter.
These ICs greatly simplify decoder switching, and can be connected to a control microprocessor using just two lines.
Applications
•
Video cassette recorders
Features
•
1) All the switching functions required for SECAM
CANAL plus decoder integrated onto one chip.
2) Built-in 9-bit serial-to-parallel converter for decoder
and TV control reduces number of microprocessor
wiring connections required.
3) Inputs have a sync-tip clamp.
4) The switch section can be used independently.
5) Low power consumption off a 5V supply.
Absolute maximum ratings (Ta = 25°C)

The measurements in the above table were made with switching voltage levels for SW1 to SW4 of "L" = 1V, and "H" = 3V.
Note 1: Connect distortion meters to the outputs. Adjust the input level so that the output distortion is 0.5% for a f = 1kHz sine wave input.
This output voltage is the maximum output level Vom (VP-P).
Note 2: Input a f = 1MHz, 1VP-P sine wave. The voltage gain GV = 20 log VOUT / VIN (dB).
Note 3: Input a f = 1MHz and 10MHz, 1VP-P sine wave. The frequency characteristic Gf = 20 log VOUT (f = 10M) / VOUT (f = 1M) (dB).
Note 4: Input a f = 4.43MHz, 1VP-P sine wave.
0dB amplifier SW crosstalk is CTM0, and the 6dB amplifier SW crosstalk is CTM6.
CTM0 = 20 log VOUT / VIN (dB)
CTM6 = 20 log VOUT / VIN + 6 (dB)

(1) Introduction
The BA7630S has 9-bit serial-to-parallel converter and
latch circuit that has been included to expand the num-
ber of microprocessor output ports. The breakdown
voltage of the output pins is 13V, so switch them in the
range 0 to 12V. In addition to controlling the BA7630S
switching block, these outputs can be used to control
audio switching, scrambling decoders, and television
sets.
(3) Pulse timing
The pulse timing diagrams are given below.

0.1µs (Typ.) 1.0µs (Max.)
(2) Using the serial-to-parallel convertor block
Signal input is basically done using clock and date
pulses. As shown in Fig.10, the date is read on the ris-
ing edge of the clock pulses. If the date is “H” on the
rising edge of the clock pulse, a “L” data bit is input to
the shift register, and if the data is “L” on the rising
edge of the clock pulse, a “H” data bit is input to the
shift register. The shift register is sequentially incre-
mented by the bit corresponding to SW1. Data in
excess of 9 bits is sequentially discarded.

(setup time)

If the data is “H” on a falling edge of the clock, the con-
tents of the shift register are read into the internal latch,
and simultaneously output to the output port (the data
polarity is inverted on output). This output is maintained
until the latch is setup again.

To reset, set the RESET pin to “H”. The internal shift
register and latch contents go low (latch output all “H”),
for the duration that RESET is held high.
