| Multimedia ICs 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 frequency range. Sync-tip clamp inputs make this an ideal switch for video signals. *Applications recorders and televisions Video cassette *Features/ 1-output switches. 1) 3-input 2) 3) 4) 5) Built-in 6dB amplifier and 75 driver.

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. *Electrical characteristic curves 5 OUTPUT VOLTAGE: VOUT (VP-P) VCC = 12V 4 4 VOLTAGE GAIN: Cf (dB) CROSSTALK: CT (dB) VCC = 9V 2 3 20 0 - 20 0 -2 2 VCC = 5V - 40 1 -4 0 0 - 60 1 2 3 4 5 100k 300k 1M 3M 10M 30M 100M - 80 100k 300k 1M 3M 10M 30M 100M INPUT VOLTAGE: VIN (VP-P) FREQUENCY: f (Hz) FREQUENCY: f (Hz) Fig. 2 VIN vs. VOUT (f = 1kHz) Fig. 3 Frequency characteristics Fig. 4 Interchannel crosstalk notes *Operationimpedance is approximately 32.
