The SY89307V is a differential receiver with a variable output swing. It is functionally equivalent to the SY100EP16VS but in an ultra-small 8-lead MLF® package that features a 70% smaller footprint. Like the EP16VS its variable output swing makes it ideal for use as a VCSEL laser driver.The operational range of the SY89307V control input is from VBB (maximum output swing) to VCC (minimum output swing). The output swing can be controlled by a variable resistor between the VBB pin and VCC with the wiper driving VCTRL.The SY89307V provides a VBB output for either singleended use or as a DC bias for AC-coupling to the device.The VBB pin should be used only as a bias for this device as its current sink/source capability is limited. Whenever used, the VBB pin should be bypassed to VCC via a 0.01µF capacitor. Under open input conditions the Q output will be LOW.
