622Mbps, Ultra-Low-Power, 3.3V

Transimpedance Preamplifier for SDH/SONET

________________General Description

____________________________Features

♦ +3.3V or +5.0V Single-Supply Operation

The MAX3665 low-power transimpedance preamplifier

for 622Mbps SDH/SONET applications consumes only

♦ 55nA

Input-Referred Noise

RMS

70mW at V

= 3.3V. Operating from a single +3.3V or

+5.0V supply, it converts a small photodiode current to a

measurable differential voltage. A DC cancellation circuit

provides a true differential output swing over a wide

range of input current levels, thus reducing pulse-width

distortion. The differential outputs are back-terminated

with 50Ω per side.

♦ 70mW Power Consumption at V

♦ 8kΩ Gain

= 3.3V

♦ 450µA Peak Input Current

♦ 260ps (max) Deterministic Jitter

The overall transimpedance gain is nominally 8kΩ. For

input signal levels beyond approximately 50µAp-p, the

amplifier will limit the output swing to 250mV. The

MAX3665’s low 55nA input noise provides a typical

sensitivity of -33.2dBm in 1300nm, 622Mbps receivers.

♦ Differential Output Drives 100Ω Load

♦ 470MHz Bandwidth

The MAX3665 is designed to be used in conjunction

with the MAX3676 clock recovery and data retiming IC

with limiting amplifier. Together they form a complete

3.3V or 5.0V 622Mbps SDH/SONET receiver.

MAX3665EUA

MAX3665E/D

In die form, the MAX3665 is designed to fit on a header

with a PIN diode. It includes a filter connection that pro-

vides positive bias for the photodiode through a 1.5kΩ

Dice

Note: Dice are designed to operate over a -40°C to +140°C

junction temperature (T ) range, but are tested and guaranteed

resistor to V . The device is available in an 8-pin

at T = +25°C.
