It is functionally equivalent to the SY100EP16VS but in an ultra-small 8-lead MLF(R) 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 VBB (maximum output swing) to VCC (minimum output swing). The output swing can be controlled by a variable resistor between the VBB pin and VCC with the wiper driving VCTRL. The SY89307V 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 this device as its current sink/source capability is limited. Whenever used, the VBB pin should be bypassed to VCC via a 0.01F capacitor. Under open input conditions the Q output will be LOW.

See "Input Interface Applications" section for single-ended inputs. Differential Outputs: Variable swing PECL/ECL output pair defaults to LOW if D inputs left open. See "Application Implementation" section for recommendations on terminations. Positive Power Supply: Bypass with 0.1F//0.01F low ESR capacitors. Negative Power Supply: VEE and Exposed pad must be tied to most negative supply. For PECL/LVPECL connect to ground. Bias Voltage: VCC-1.3V. Used as reference voltage when AC-coupling to the D, /D inputs. Bypass with 0.01F capacitor to VCC.

Permanent device damage may occur if ABSOLUTE MAXIMUM RATINGS are exceeded. This is a stress rating only and functional operation is not implied at conditions other than those detailed in the operational sections of this data sheet. Exposure to ABSOLUTE MAXIMUM RATlNG conditions for extended periods may affect device reliability. 2. The data sheet limits are not guaranteed if the device is operated beyond the operating ratings. 3. Due to the limited drive capability use for input of the same package only. 4. Package thermal resistance assumes exposed pad is soldered (or equivalent) to the devices most negative potential on the PCB.

Precison Edge(R) SY89307V AC ELECTRICAL CHARACTERISTICS VCC = +3.3V 10% or +5V 10% and VEE = 0V; VCC = 0V and VEE = -3.3V 10% or -5V 10%; TA = -40C to +85C, RL = 50 to VCC -2V unless otherwise noted. Symbol fMAX tpd VPP VCMR tr, tf Notes: 5. Minimum input swing for which AC parameters are guaranteed. The device has a DC gain of 40 when output has a full swing. 6. 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.)|. 7. Output at full swing.
