DESCRIPTION
The SY100EP16VS are differential receivers with variable output swing. The devices are functionally equivalent to the EP16V devices with an input that controls the amplitude of the outputs. EP16VS is commonly used as VCSEL laser driver. The operational range of the EP16VS control input is from VBB (max. swing) to VCC (min. swing). Simple control of the output swing can be obtained by a variable resistor between the VBB pin and VCC with the wiper driving VCTRL. The EP16VS provides a VBB output for either singleended use or as a DC bias for AC coupling to the device. The V BB pin should be used only as a bias for the EP16VS as its current sink/source capability is limited. Whenever used, the VBB pin should be bypassed with a 0.01F capacitor to VCC (in PECL mode). Under open input conditions (pulled to VEE), internal input clamps will force the Q output LOW.

Minimum input swing for which AC parameters are guaranteed. The device has a DC gain of 40 when output has a full swing. The CMR range is referenced to the most positive side of the differential input signal. Normal operation is obtained if the HIGH level falls within the specified range and the peak-to-peak voltage lies between VPP (min.) and 1V. The lower end of the CMR range varies 1:1 with VEE. The numbers in the spec table assume a nominal VEE = -3.3V and VCC = 0V. Note for PECL operation, the VCMR (min.) will be fixed at 3.3V - |VCMR (min.)|. Output at full swing.
