BA7613N / BA7613F
The BA7613N and BA7613F are three-channel analog multiplexers with built-in mute, 6dB amplifier and 75Ω 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.
•Applications
Video cassette recorders and televisions
•Features
1) 3-input / 1-output switches.
2) Built-in 6dB amplifier and 75Ω driver.
3) Built-in mute.
4) Sync-tip clamp inputs.
5) Wide operating supply voltage range
(4.5V ~ 13.0V, BA7613N)
(4.5V ~ 9.5V, BA7613F).
6) Low power consumption (100mW Typ.).
7) Excellent frequency characteristics
(10MHz, 0dB Typ.).
8) Wide dynamic range (3.5VP-P Typ.).
9) Low interchannel crosstalk
( – 65dB Typ., f = 4.43MHz).

∗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 Vom (VP-P).
∗2: Input a 1VP-P, 1MHz sine wave. The voltage gain is given by GV = 20 log (VOUT / VIN) + 6.
∗3: Input a 1VP-P, 4.43MHz sine wave. The interchannel crosstalk is given by CT = 20 log (VOUT / VIN).
∗4: Input 1VP-P, 1MHz and 10MHz sine waves.
The frequency characteristic is given by Gf = 20 log (VOUT (f = 10MHz) / VOUT (f = 1MHz)).
∗5: Input a 1VP-P, 1MHz sine wave. Reduce the CTL pin voltage from VCC.
The CTL pin switching level (VTH) is the CTL pin voltage at which the VOUT level drops below 20mVP-P.

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