The HXR5004A Transimpedance Limiting Amplifier array is a member of the 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 telecom and datacom applications.

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

Key Features

  • 20 mApp receiver sensitivity for 10-12 BER at 10.3 Gbps. Better than 1.5 mApp overload
  • 66 mW per channel power consumption with low power setting
  • Adjustable output swing size and pre-emphasis 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
  • QSFP MSA compliance

Applications List

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