5 / 9 page Detailed Description The MAX3275/MAX3277 are transimpedance amplifiers designed for up to 2.125Gbps fibre channel applica- tions. A functional diagram of the MAX3275/MAX3277 is shown in Figure 1. The MAX3275/MAX3277 comprises a transimpedance amplifier stage, a voltage amplifier stage, an output buffer, and a direct-current feedback cancellation circuit. Transimpedance Amplifier Stage The signal current at the input flows into the summing node of a high-gain amplifier. Shunt feedback through the resistor RF converts this current to a voltage. In par- allel with the feedback are two back-to-back Schottky diodes that clamp the output signal for large input cur- rents as shown in Figure 2. Voltage Amplifier Stage The voltage amplifier stage provides gain and converts the single-ended input to differential outputs.

Current flowing into IN causes the voltage at OUT- to decrease. 4 3 OUT+ Noninverting Data Output. Current flowing into IN causes the voltage at OUT+ to increase. 6 6 N.C. No Connection. Not internally connected. 7 7 FILTER Provides bias voltage for the photodiode through a 600 Ω resistor to VCC. When grounded, this pin disables the DC cancellation amplifier to allow a DC path from IN to OUT+ and OUT- for testing. 8 8 IN TIA Input. Signal current from photodiode flows into this pin.
