Limiting amp with compatible pin-out has programmable loss-of-signal

Sunnyvale, CA — April 20, 2004-Maxim Integrated Products introduces the MAX3747/MAX3747A 3.3V, low-power, multirate limiting amplifiers with a programmable loss-of-signal (LOS) indicator. Pin-compatible to the Micrel SY88993V limiting amplifier, these devices provide higher gain, better bit-error-rate performance, and lower jitter than the SY88993V.

Operating from a single 3.3V supply, the MAX3747/MAX3747A have better than 4mV input sensitivity and 120 microvolts root-mean-square input-referred noise, while consuming only 60mW. Each amplifier has a programmable signal-detect function that can be set to different assert and de-assert levels, while maintaining a 2dB hysteresis. The MAX3747 features low 13ps deterministic jitter and less than 3.5ps root-mean-square random jitter. The devices accept input voltages from 4mV to 1200mV, and provide 500mV peak-to-peak (MAX3747) or 800mV peak-to-peak (MAX3747A) output swing.

The MAX3747/MAX3747A are packaged in a 3mm, 10-pin microMAX and operate over the extended temperature range (-40 degrees Celsius to +85 degrees Celsius). Prices start at $4.50 (1000-up, FOB USA). An evaluation kit is available to speed designs.
