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