DESCRIPTION
Precision Edge^®
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 V_BB (maximum output swing) to V_CC (minimum output
swing). The output swing can be controlled by a variable
resistor between the V_BB pin and V_CC with the wiper driving
V_CTRL.
The SY89307V provides a V_BB output for either single-
ended use or as a DC bias for AC-coupling to the device.
The V_BB pin should be used only as a bias for this device
as its current sink/source capability is limited. Whenever
used, the V_BB pin should be bypassed to V_CC via a 0.01µF
capacitor.
Under open input conditions the Q output will be LOW.
