MAX9652

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 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 MAX9653/MAX9654 feature a low-power, 12A shutdown mode. The MAX9652/MAX9653/MAX9654 are specified over the -40°C to +125°C automotive temperature range. The MAX9652/MAX9653/MAX9654 are 3.3V, triplechannel, 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 synctip clamp while PBIN and PRIN have keyed clamps. The output buffer has gain of 2V/V and drives a standard back-terminated 75 video load.

The features of MAX9652 can be summarized as (1)9.5mA/channel supply current; (2)selectable lowpass filter for high-definition or standard-definition video signals (MAX9654); (3)8.5MHz standard-definition passband with 57dB attenuation at 27MHz; (4)42MHz high-definition passband with 50dB attenuation at 109MHz; (5)2V/V gain; (6)3.135V to 3.465V single-supply operation; (7)12A shutdown mode (MAX9653/MAX9654).

The absolute maximum ratings of MAX9652 are (1)VDD to GND:-0.3V to +4V; (2)YIN, PRIN, PBIN to GND: -0.3V to (VDD + 0.3V); (3)SHDN, SD/HD to GND:-0.3V to +4V; (4)maximum current into any input Pin: ±20mA; (5)output short-circuit current duration to VDD or GND: Continuous; (6)continuous power dissipation (TA = +70°C)8-Pin SO (derate 5.9mW/°C above +70°C):471mW; (7)10-Pin MAX (derate 5.6mW/°C above +70°C): 444mW; (8)operating temperature range: -40°C to +125°C; (9)junction temperature:+150°C; (10)storage temperature range: -65°C to +150°C; (11)lead temperature (soldering, 10s): +300°C.
