MAX3970
10Gbps, 3.3V Low-Power Transimpedance Amplifier with RSSI
Part Details
- 150mW Power Dissipation at 3.3V Supply
- 1.1µARMS Noise (-18dBm Sensitivity)
- 9GHz Bandwidth
- 2mAP-P Input Overload
- Received-Signal Strength Indication
- 8psP-P Typical Jitter Generation at 1.3mAP-P Input Current
- 600V/A Transimpedance
The MAX3970 is a compact, low-power transimpedance amplifier (TIA) optimized for use in 10Gbps optical receivers. The TIA provides transimpedance at 600V/A with 50Ω differential CML outputs. The MAX3970 has a typical input-referred noise of 1.1µA, and when coupled with a high-speed photodiode, achieves -18dBm sensitivity and +2mA input overload. A received-signal strength indicator (RSSI) simplifies optical assembly. The circuit operates from a single 3.3V supply over a junction temperature range from 0°C to +110°C.
Applications
- 10.3Gbps Ethernet Optical Receivers
- Fibre Channel Optical Receivers
- OC-192 VSR Optical Receivers
