MAX3793 Datasheet | Maxim Integrated

Description The MAX3793 transimpedance amplifier provides a pact low-power solution for applications from 1Gbps up to 4.25Gbps. The MAX3793 features 195n A input-referred noise, 3.5kΩ transimpedance gain, 2.9GHz bandwidth (CIN = 0.3p F) and 2.8m AP-P input overload. Operating from a +3.3V supply, the MAX3793 consumes only 106m W. An integrated filter resistor provides positive bias for the photodiode. These features , bined 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 -20d Bm (0.55A/W) at 4.25Gbps. Typical optical overload is at 4d Bm. The MAX3793 and the MAX3794 limiting amplifiers provide a plete solution for multirate receiver applications. - 4.7ps P-P Deterministic Jitter (DJ) - 195n ARMS Input-Referred Noise - 2.9GHz Small-Signal Bandwidth - 2.8m AP-P AC Overload - Photocurrent Output Monitor - 3.5kΩ Differential Gain - pact Die Size (30 mils x 50 mils) Features Applications SFF/SFP Transceiver Modules from 1Gbps to 4.25Gbps Gigabit Ethernet Optical Receivers Multirate Fibre-Channel Optical Receivers PART Ordering Information TEMP RANGE PIN-PACKAGE MAX3793E/D -40°C to +85°C Dice- - Dice are designed to operate from -40°C to +85°C ambient temperature, but are tested and guaranteed only at TA = +25°C.
