The MAX9652/MAX9653/MAX9654 are 3.3V, triple-channel, high-definition (HD) video-filter amplifiers. Specially designed for YPbPr component video signals, these devices are ideal for a wide range of set-top box and portable applications. The inputs to the MAX9652/ MAX9653/MAX9654 are AC-coupled. YIN has a sync- tip clamp while PBIN and PRIN have keyed clamps. The output buffer has gain of 2V/V and drives a stan- dard back-terminated 75Ω video load. The passband of the MAX9654 is logic selectable between standard definition (SD) and high definition. The MAX9652/MAX9653 have a fixed passband for HD video. The MAX9654 SD lowpass filter has ±1dB passband out to 8.5MHz and 57dB attenuation at 27MHz. The MAX9652/MAX9653/MAX9654 HD lowpass filter have ±1dB passband out to 42MHz and 50dB attenuation at 109MHz. The devices consume only 9.5mA per channel and operate from a 3.3V supply. The MAX9653/MAX9654 feature a low-power, 12µA shutdown mode. The MAX9652/MAX9653/MAX9654 are specified over the -40°C to +125°C automotive temperature range.
The MAX9652, MAX9653 and MAX9654 are 3.3 V, triple‑channel video‑filter amplifiers designed for YPbPr component video. They provide a fixed 2 V/V gain and can drive standard 75 Ω video loads. The MAX9654 adds a logic‑selectable passband for standard‑definition (SD) or high‑definition (HD) video, while the MAX9653 and MAX9654 include a low‑power shutdown mode.
These devices operate over an automotive temperature range of –40 °C to +125 °C, consume only 9.5 mA per channel in normal operation, and feature AC‑coupled inputs with sync‑tip and keyed clamps to protect the video signals. Detailed electrical characteristics, gain versus frequency plots, and typical application circuits are provided.
