HA457 Datasheet 95mhz/ Low Power/ Av = 2/ 8 X 8 Video Crosspoint Switch

Manufacturer: Intersil (now Renesas)

Overview: HA457 Data Sheet August 1999 File Number 4231.2 95MHz, Low Power, AV = 2, 8 x 8 Video Crosspoint Switch The HA457 is an 8 x 8 video crosspoint switch suitable for high performance video systems. Its high level of integration significantly reduces ponent count, board space, and cost. The crosspoint switch contains a digitally controlled matrix of 64 fully buffered switches that connect eight video input signals to any, or all, matrix outputs. Each matrix output connects to an internal, high-speed (275V/µs), gain of two buffer capable of driving 150Ω to ±2.5V. The HA457 will directly drive a double terminated video cable with some degradation of differential gain and phase. Applications demanding the best posite video performance should drive the cable with a unity gain video buffer, such as the HFA1412 quad buffer (see Figure 7). This crosspoint’s three-state output capability makes it feasible to parallel multiple HA457s and form larger switch matrices.
