SK10/100EL16V Differential Receiver with Variable Output Swing HIGH-PERFORMANCE PRODUCTS EDGE HIGH-PERFORMANCE PRODUCTS Description Features The SK10/100EL16V is a differential receiver with variable output swing. Its VCTRL input controls the amplitude of the Q and Q* outputs. The operating range of the EL16V control input, VCTRL, is from VBB (large swing) to VCC (min swing), see Figure 2. Simple control of the output swing can be obtained by a variable resistor between the VBB and VCC pins, with wiper driving CTRL. Typical application circuits and results are described in Figures 1a, 1b, and 2. • • • • • • • • • The SK10/100EL16V provides a VBB output for either single-ended use or as a DC bias for AC coupling to the device. The VBB pin should be used only as a bias for the EL16V as its current sink/source capability is limited. Whenever used, the VBB pin should be bypassed to VCC via a 0.01 µF capacitor. • Under open input conditions, the pulldown resistor on D, pulldown and pullup resistors on D* will force the Q output LOW and Q* output HIGH. The VCTRL pin should be bypassed to VCC via a 0.01 µF capacitor when the pin is used.

The circuit is in a test socket or mounted on a printed circuit board and transverse airflow greater than 500 lfpm is maintained. Outputs are terminated through a 50Ω resistor to VCC–2.0V. 2. 100K circuits are designed to meet the DC specification shown in the table where transverse airflow greater than 500 lfpm is maintained. 3. Duty cycle skew is the difference between TPLH and TPHL propagation delay through a device. 4. Fmax guaranteed for functionality only. See Figure 3 for typical output swing. VOP-P levels are guaranteed at DC only. 5. VCTRL voltage range should be between VBB to VCC. 6. The device has a DC gain of ~40. 7. 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 and is equal to VEE + 1.7V. 8. VOP-P is obtained as follows: Voltages of Q and Q* outputs with respect to VCC are measured. The absolute difference between a high and a low state is equal to VOP-P. 9. Voltages referenced to VCC = 0V. 10. Minimum input swing for which parameters are guaranteed. 11.
