The MAX9675 is a nonblocking 16 x 16 video cross-point switch with buffered inputs and outputs from Maxim Integrated Products. 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 applications.
The MAX9675 video crosspoint switch provides a 16 × 16 non‑blocking matrix with buffered inputs and outputs that can drive standard 75 Ω video loads. It operates from ±5 V analog supplies and uses a separate 2.7 V–5 V digital supply. The switching matrix and per‑channel gain (AV = +1 V/V or +2 V/V) are controlled via a 3‑wire SPI/QSPI‑compatible serial interface.
Designed for security, surveillance, and video‑on‑demand systems, the device offers a -3 dB bandwidth of 110 MHz, -62 dB crosstalk and -110 dB isolation at 6 MHz, and is available in a 100‑pin TQFP package with an operating temperature range of –40 °C to +85 °C.
