5V/3.3V 2.5Gbps VARIABLE OUTPUT SWING DIFFERENTIAL RECEIVER FEATURES SY100EP16VS DESCRIPTION ■ 3.3V and 5V power supply options ■ Fast output transitions <160ps tr / tf 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 to ground via a 0.01µF capacitor. Under open input conditions (pulled to V EE), internal input clamps will force the Q output LOW. ■ Guaranteed operation over –40°C to +85°C temperature range ■ Functionally equivalent to SY88927V and SY10EP16V ■ Variable output swing from 100mV to 700mV ■ Available in 8-pin (3mm) EPAD-MSOP package PIN CONFIGURATION/BLOCK DIAGRAM VCTRL 1 8 VCC D 2 7 Q /D 3 6 /Q VBB 4 5 VEE APPLICATIONS ■ Multimode optical transceiver ■ VCSEL driver ■ Backplane receiver PIN NAMES 8-pin EPAD-MSOP Pin Function D, /D PECL Data Inputs Q, /Q Data Outputs VBB Reference Voltage Output VCTRL Output Swing Control VCC Most Positive Power Supply Input VEE Most Negative Power Supply Input Rev.: A 1 Amendment: /0 Issue Date: November 2001 SY100EP16VS Micrel ABSOLUTE MAXIMUM RATINGS(1) Symbol Rating Value Unit VEE Power Supply Voltage (VCC = 0) –6.0 to 0 V VCC Power Supply Voltage (VEE = 0) +6.0 to 0 V VIN Input Voltage (VCC = 0V, VIN not more negative than VEE) Input Voltage (VEE = 0V, VIN not more negative than VCC) –6.0 to 0 +6.0 to 0 V V IOUT Output Current 50 mA 100 IBB VBB Sink/Source Current(2) ±0.5 mA TA Operating Temperature Range –40 to +85 °C Tstore Storage Temperature Range –65 to +150 °C θJA Package Thermal Resistance (Junction-to-Ambient) 38 °C/W –Continuous –Surge –Still-Air NOTE: 1.

Minimum input swing for which AC parameters are guaranteed. The device has a DC gain of ≈40 when output has a full swing. 2. 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.)|. 3. Output at full swing.
