Video signal switcher
BA7613N / BA7613F
The BA7613N and BA7613F are three-channel analog multiplexers with built-in mute, 6dB amplifier and 75
driver.
The ICs designed for use in video cassette recorders, and feature a large dynamic range and wide operating fre-
quency range. Sync-tip clamp inputs make this an ideal switch for video signals.

1: Connect a distortion meter to the output, and input a f = 1kHz sine wave. Adjust the input level until the output distortion is 0.5%. This
output voltage at this time multiplied by 2 is the maximum output level V
om
(V
P-P
).
2: Input a 1V
P-P
, 1MHz sine wave. The voltage gain is given by G
V
= 20 log (V
OUT
/ V
IN
) + 6.
3: Input a 1V
P-P
, 4.43MHz sine wave. The interchannel crosstalk is given by C
T
= 20 log (V
OUT
/ V
IN
).
4: Input 1V
P-P
, 1MHz and 10MHz sine waves.
The frequency characteristic is given by G
f
= 20 log (V
OUT
(f = 10MHz) / V
OUT
(f = 1MHz)).
5: Input a 1V
P-P
, 1MHz sine wave. Reduce the CTL pin voltage from V
CC
.
The CTL pin switching level (V
TH
) is the CTL pin voltage at which the V
OUT
level drops below 20mV
P-P
.

Operation notes
The output impedance is approximately 32
. Therefore,
to ensure output matching, connect an external resistor of 43
.
