Description
The growing use of the Internet has created increasingly higher demand for multi-Gb/s I/O performance. The demand and availability of 10 Gb/s+ WAN bandwidth fuels the growth of native 10 Gb/s infrastructures within MAN and enterprise datacenters.

Features
• Integrated transimpedance and limiting amplifier for serial optical receiver applications
• Receiver sensitivity 20 µApp for 10-12 BER at 10 Gb/s
• Receive signal strength indicator (RSSI) for digital diagnostics and active alignment
• Loss of signal indicator (LOS)
• Optional squelch circuit disables output at low input levels
• Back-terminated 50-ohm CML output providing 250 mVpp differential amplitude
• No external passives required for photodiode bias network
• Single +3.3 V supply dissipating 115 mW

Applications
• 850 nm and 1310 nm receive optical subassemblies (ROSA)
• XFP, X2, XPAC, XENPAC optical modules
• 10GbE, 10GFC, 8GFC, 4GFC, OC-192 VSR
