DESCRIPTION
The SA5217 is a 75MHz postamplifier system designed to accept low level high-speed signals. These signals are converted into a TTL level at the output. The SA5217 can be DC coupled with the previous transimpedance stage using SA5210, SA5211 or SA5212A transimpedance amplifiers.

FEATURES
• Postamp for the SA5211/5212A. SA5210 preamplifier family
• Wideband operation: typical 75MHz (150MBaud NRZ)
• Interstage filtering/equalization possible
• Single 5V supply
• Low signal flag
• Output disable
• Link status threshold and hysteresis programmable
• LED driver (normally ON with above threshold signal)
• Fully differential for excellent PSRR
• Auto-zero loop for DC offset cancellation
• 2kV ElectroStatic Discharge (ESD) protection

APPLICATIONS
• Fiber optics
• Communication links in Industrial and/or Telecom environment with high EMI/RFI
• Local Area Networks (LAN)
• Synchronous Optical Networks (SONET) STS-1
• RF limiter
• Good for 223 -1 pseudo random bit stream
