3.3V, HD/SD Triple-Channel Filter Amplifiers with Shutdown

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 standard 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.
