5V/3.3V VARIABLE OUTPUT SWING DIFFERENTIAL RECEIVER Micrel, Inc. FEATURES SY100EL16VS SY100EL16VS DESCRIPTION ■ 3.3V and 5V power supply options ■ High bandwidth output transitions ■ Internal 75KΩ pull-down resistors on inputs ■ Functionally equivalent to SY100EL16V with variable output swing ■ Improved output waveform characteristics ■ Available in 8-pin SOIC and 8-pin (3mm) MSOP The SY100EL16VS are differential receivers with variable output swing. The devices are functionally equivalent to the EL16V devices with an input that control the amplitude of the outputs. The operational range of the EL16VS 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 EL16VS 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 the EL16VS as its current sink/source capability is limited. Whenever used, the VBB pin should be bypassed to ground via a 0.01µF capacitor. Under open input conditions (pulled to VEE), internal input clamps will force the Q output LOW.

Parametric values specified at: 100EL16VS Series: –3.0V to –5.5V. 2. Duty cycle skew is the difference between a tPLH and tPHL propagation delay through a device. 3. Minimum input swing for which AC parameters are guaranteed. The device has a DC gain of ≈40 when output has a full swing. 4. 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. Note for PECL operation, the VCMR (min) will be fixed at 3.3V – |VCMR (min)|.
