Maxim introduces the MAX3747/MAX3747A multirate limiting amplifiers with a programmable loss-of-signal (LOS) indicator. Operating from a 3.3 V supply, the devices have better than 4 mV input sensitivity and 120 microvolts root-mean-square input-referred noise, while consuming only 60 mW. Each amplifier has a programmable signal-detect function that can be set to different assert and deassert levels, while maintaining a 2dB hysterisis. The MAX3747 features low 13 ps deterministic jitter and less than 3.5 ps root-mean-square random jitter. The devices accept input voltages from 4 mV to 1200 mV, and provide 500 mV peak-to-peak (MAX3747) or 800 mV peak-to-peak (MAX3747A) output swing. The devices are packaged in a 3 mm, 10-pin microMAX and operate over the temperature range of 㫀° C to +85° C.
