DATA SHEET
1/2/4/8 GBPS 850NM PIN + PREAMP LC ROSA PACKAGE
HFD7180-XXX
FEATURES:
LC ROSA HFD7180-413 includes flex circuit LC ROSA HFD7180-001 leaded package High performance GaAs PIN photodiode with separate transimpedance amplifier Low electrical parasitic TO46 package Data rates from 1Gbps to 8.5Gbps Received signal strength indicator with bandwidth select Low bias currents and voltages Low power dissipation
The HFD7180-xxx use a high-performance GaAs PIN photo-detector packaged with a transimpedance amplifier designed to meet performance requirements for data rates up to 8.5Gbps data communication over multi-mode optical fiber at 850nm. Applications include Ethernet, Fiber Channel and ATM protocols. The optical assembly is designed to interface either 50m or 62.5m multimode fiber. The HFD7180-xxx is designed to be paired with AOC VCSEL TOSA products (see data sheets for HFE719x products).

NOTICE: Stresses greater than those listed under "Absolute
Maximum Ratings" may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operations section for extended periods of time may affect reliability.
NOTICE: The inherent design of this component causes it
to be sensitive to electrostatic discharge (ESD). To prevent ESD-induced damage and/or degradation to equipment, take normal ESD precautions when handling this product.

Bandwidth and Low Frequency Cutoff are measured with a small signal sinusoidal light source with -10dBm average power Sensitivity is measured with an optical source with an extinction ratio of 3dB. For sensitivity measurements at 2 and 4Gbps, bandwidth limiting of the TIA is assumed to be implemented at the front end of the post amplifier. Rise/Fall times are corrected for optical source Rise/Fall
