Description

The MAX3657 is a transimpedance preamplifier for receivers operating up to 155Mbps. The low noise, high gain, and low-power dissipation make it ideal for Class-B and Class-C passive optical networks (PONs).

The MAX3657 features 14nA input-referred noise, 130MHz bandwidth, and 2mA input overload. Low jitter is achieved without external compensation capacitors.

Operating from a +3.3V supply, the MAX3657 con- sumes only 76mW power. An integrated filter resistor provides positive bias for the photodiode. These fea- tures, combined with a small die size, allow easy assembly into a TO-46 header with a photodiode. The MAX3657 includes an average photocurrent monitor.

The MAX3657 has a typical optical sensitivity of -38dBm (0.9A/W), which exceeds the Class-C PON require- ments. Typical overload is 0dBm. The MAX3657 is avail- able in die form with both output polarities (MAX3657E/D and MAX3657BE/D.) The MAX3657 is also available in a 12-pin, 3mm x 3mm thin QFNpackage.
