Renesas Electronics Corporation Specialized ICs HA4201CB

The HA4201CB is a 1 x 1 video crosspoint switch designed for high-performance applications such as professional video switching, HDTV, and computer monitor routing. It operates at a bandwidth of 480MHz and features low power dissipation of 105mW when enabled and 1mW when disabled. The device provides excellent differential gain and phase performance, with a differential gain of 0.01% and a differential phase of 0.01 degrees. It also boasts high off isolation of 85dB at 100MHz, making it suitable for routing matrix equipment. The HA4201CB includes a TTL compatible enable input and an open collector tally output, which indicates crosspoint selection when enabled. It requires no external current source and has fast switching capabilities with symmetrical slew rates of 1700V/¬µs. The device is rated for operation within a temperature range of 0¬8C to 70¬8C and has a high ESD rating of over 1800V. This crosspoint switch is particularly effective as an input buffer for routers with multiple outputs, providing superior performance compared to traditional video amplifiers. It is packaged in an 8-lead SOIC format, making it suitable for various applications in video multiplexing and RF switching.
