DESCRIPTION
The SY89313V is a differential ECL/PECL integrated /4 divider clock generator. It is functionally equivalent to the SY100EP33V but in an ultra-small 8-lead MLF(R) package that features a 70% smaller footprint. The VBB pin, an internally generated voltage supply, is available for this device only. For single-ended input conditions, the unused differential input is connected to VBB as a switching reference voltage. VBB may also re-bias ACcoupled inputs. When used, decouple VBB and VCC via a 0.01F capacitor and limit current sourcing or sinking to 0.5mA. When not used, VBB should be left open. The reset pin is asynchronous and is asserted on the rising edge. Upon power-up, the internal flip-flops will be in a random state; the reset allows for the synchronous use of multiple SY89313V's in a system.

PIN DESCRIPTION
Pin Number 2, 3 Pin Name CLK, /CLK Type 100K ECL/PECL Input 100K Output Positive Power Supply Negative Power Supply Reference Voltage Output 100EP Input Pin Function Differential PECL/ECL Input: Internal 75k pull-down resistor. If left open, pin defaults LOW. See "Input Interface Applications" section for single-ended inputs. Differential PECL/ECL Output: Output CLK input divided by 4. See "Output Interface Applications" 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 Reference Voltage: VCC-1.4V. Used as reference voltage for singleended input or AC-coupling to the CLK, /CLK inputs. Max sink/source is 0.5mA. See "Input Interface Applications" section. Single-ended Input: PECL/ECL Asynchronous reset.

Notes: 1. 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. 5. VIHCMR (min) varies 1:1 with VEE, (max) varies 1:1 with VCC.
