FAIRCHILD Semiconductor, represented by Arrow Electronics , has released the industry’s first high-bandwidth 3-port 3:1 video switch.

The FSAV433 optimises high-performance operation for LCD displays that require switching of three computer RGB or high-definition YPbPR analogue video signals.

The FSAV433’s high bandwidth and low differential gain and phase provide minimal signal distortion, high video image integrity and “transparent” switching operation.

The ultra-low power FSAV433 is complemented by excellent Off Isolation and crosstalk characteristics eliminating active channel-to-channel noise and annoying ghosting effects in the display.

Moreover, the switch’s low On Resistance (RON) results in minimal signal insertion loss, further increasing signal quality.

Key features of the FSAV433 3:1 video switch include:

* High bandwidth: 550 MHz, -3 dB;

* Low differential gain: 0.2%, typical;

* Low differential phase: 0.1 degree, typical;

* Ultra-low power consumption: less than 1 µA;

* Excellent Off Isolation: less than 75 dB;

* Superior crosstalk characteristics: -85 dB;

* Low On Resistance: 6.5 Ohms, typical.

Designed with full application flexibility in mind, the FSAV433 comes in a choice of 20-pin TSSOP or ultra-compact 20-terminal DQFN configurations.

For space-limited designs, DQFN is 75% smaller than TSSOP devices, runs cooler and generates lower noise and crosstalk between I/O terminals due to DQFN’s lower capacitance and inductance.

The lead-free FSAV433 meets or exceeds the requirements of the joint IPC/JEDEC standard J-STD-020B and is compliant with European Union requirements now in effect.
