1Gbps to 4.25Gbps Multirate Transimpedance
Amplifier with Photocurrent Monitor
General Description
The MAX3793 transimpedance amplifier provides a
compact low-power solution for applications from
1Gbps up to 4.25Gbps.
The MAX3793 features 195nA input-referred noise,
3.5kΩ transimpedance gain, 2.9GHz bandwidth (CIN =
0.3pF) and 2.8mAP-P input overload. Operating from a
+3.3V supply, the MAX3793 consumes only 106mW. An
integrated filter resistor provides positive bias for the
photodiode. These features, combined with a small die
size, allow easy assembly into a TO-46 header with a
photodiode. The MAX3793 also includes an average
photocurrent monitor.
The MAX3793 has a typical optical sensitivity of -20dBm
(0.55A/W) at 4.25Gbps. Typical optical overload is
at 4dBm. The MAX3793 and the MAX3794 limiting
amplifiers provide a complete solution for multirate
receiver applications.
Features
♦ 4.7psP-P Deterministic Jitter (DJ)
♦ 195nARMS Input-Referred Noise
♦ 2.9GHz Small-Signal Bandwidth
♦ 2.8mAP-P AC Overload
♦ Photocurrent Output Monitor
♦ 3.5kΩ Differential Gain
♦ Compact Die Size (30 mils x 50 mils)
Applications
SFF/SFP Transceiver Modules from 1Gbps to
4.25Gbps
Gigabit Ethernet Optical Receivers
Multirate Fibre-Channel Optical Receivers
