The HXR5112A Transimpedance Limiting Amplifier array is a member of GigPeak’s family of Optical Receiver Transmitter Array (ORTA) products targeted at the parallel optical links market. Together with a PIN detector array or discrete detectors, high-capacity, high-availability optical links can be designed for datacom applications.

The 3.3V SiGe device integrates the transimpedance pre-amplifier, the limiting post-amplifier and a versatile CML output stage for twelve optical channels.

Key Features

  • 20 App receiver sensitivity for 10-12 BER at 10.3 Gbps. Better than 1.0mApp overload
  • 66 mW per channel power consumption
  • Adjustable output swing size and preemphasis in limiting mode and signal detect threshold
  • Independent RSSI
  • Optimized for isolated and common cathode photo-detector arrays from multiple vendors
  • Control lines accessible on both sides of the chip

Applications List

  • IEEE 802.3ba Ethernet transceivers
  • Infiniband QDR & FDR active cables
  • Proprietary multi-channel optical modules
