A novel video signal switcher IC can reduce the component count, design complexity and power consumption of VCRs, televisions, cameras and other applications that require video signal switching. Rohm's new BA7613F video signal switcher IC integrates a three-channel analogue multiplexer, a 6dB amplifier, a 75ohm driver and a mute function into a single SOP-8 device with dimensions of just 5.0 x 4.4 x 1.5mm. The device offers three sync-tip clamp inputs, a single output and two control terminals.
Compatible with a wide operating supply voltage of between 4.5 and 9.5V, the BA7613F has excellent frequency characteristics (typically 0dB at 10MHz) and offers a typical maximum output level of 3.5V peak-peak.
The device also features low typical channel-to-channel crosstalk rated at just -65dB at a frequency of 4.43MHz.
The BA7613F is specified for operation at temperatures between -25 and +75C and has a maximum power dissipation of 550mW.
