具有输出波形整形的 11.3Gbps 差动 VCSEL 驱动器
The is a high-speed, 3.3V laser driver designed to directly modulate VCSELs at data rates from 2 Gbps up to 11.3 Gbps.
The device provides a two-wire serial interface which allows digital control of the modulation and bias currents, eliminating the need for external components. Output waveform control, in the form of cross point control and independent over- and undershoot capability on the rising and falling edges is also available to improve VCSEL edge speeds and the optical eye diagram. An optional input equalizer can be used for equalization of up to 300mm 12 inch of microstrip or stripline transmission line on FR4 printed circuit boards.
The ONET8501V includes an integrated automatic power control APC loop as well as circuitry to support laser safety and transceiver management systems. The VCSEL driver is characterized for operation from -40°C to 85°C ambient temperatures and is available in a small footprint 4mm × 4mm 20 pin RoHS compliant QFN package.
