The MAX9675 is a nonblocking 16 x 16 video crosspoint switch with buffered inputs and outputs. The device operates on ±5V analog supplies. Digital logic is supplied separately from an independent +2.7V to +5V supply. The MAX9675 inputs and outputs are buffered with all outputs able to drive a standard 75Ω reverse-terminated video load. The switching matrix and programmable gain are controlled through an SPI™/QSPI™-compatible 3-wire serial interface. The serial interface is designed to operate in either of two modes to provide fast updates and initialization. All outputs are held in the disabled state during power-up to avoid signal conflicts in large switching arrays. The programmability and high level of integration make the MAX9675 an ideal choice for nonblocking video switch arrays.
The MAX9675 video crosspoint switch provides a non‑blocking 16 × 16 matrix with buffered inputs and outputs, operating from a +5 V analog supply and a separate +2.7 V to +5 V digital supply. It offers individually programmable output buffer gain (Av = +1 V/V or +2 V/V) and high‑impedance output disable for wired‑OR connections.
Designed for security, surveillance, and video‑on‑demand systems, the device features a -3 dB bandwidth of 110 MHz, gain flatness of 0.1 dB to 14 MHz, and excellent isolation (‑62 dB crosstalk, ‑110 dB isolation at 6 MHz). It is supplied in a 100‑pin TQFP package and operates over a temperature range of ‑40 °C to +85 °C.
