Micrel, Inc. 3.3V, 2.7Gbps SDH/SONET SY88952L LASER DRIVER WITH AUTOMATIC SY88952L POWER CONTROL FEATURES DESCRIPTION Single 3.3V power supply SY88952L is a highly integrated and programmable Up to 2.7Gbps operation laser driver for SONET/SDH application up to 2.7Gbps. The device accepts differential PECL or LVDS data and Rise/Fall times: 75ps clock inputs. It provides programmable bias and Independent programmable laser modulation and modulation currents for driving a laser. The modulation bias currents output of SY88952L can be DC-coupled to drive the laser Bias current to 100mA and modulation current to diode, providing a significant power saving over AC- 90mA coupled operation. A synchronizing TTL input latch can Automatic average laser power control be used to reduce jitter if a clock signal is available. A TTL enable is also incorporated in the device. EN only Bias and modulation current monitors
