FEATURES
s s s s s s fMAX > 2.5GHz Inputs (D, /D) include 75k pull-down resistors SY89306V: 100k EP compatible SY89316V: 10k EP compatible Industrial temperature range: -40C to +85C Available in an ultra-small 8-pin (2mm x 2mm) MLFTM package Precision Edge(R)
DESCRIPTION
The SY89306V and SY89316V are a high-speed buffer/ receivers. The devices are functionally equivalent to the 10/100EP16 buffers, but feature a 70% smaller footprint. The SY89306/316V includes a VBB reference for singleended AC-coupling applications. Whenever used, the VBB pin should be bypassed to ground via a 0.01F capacitor. VBB reference can only sink/source 0.5mA. Under open input conditions (pulled to VEE), internal input clamps will force the Q output LOW.

PIN DESCRIPTION
SY89306V
Pin Number 2, 3 Pin Name D, /D Type 100k ECL Input Pin Function Differential PECL/ECL Input: The signal inputs include internal 75k pulldown resistors. If inputs are left open, Q output will default to LOW. See "Input Interface Applications" section for single-ended inputs. Differential PECL/ECL Output: Defaults to LOW if D inputs left open. 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 Voltage: VCC-1.4V. Used as reference voltage when AC coupling to the D, /D inputs. Max sink/source is 0.5mA. No connection.

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. Package Thermal Resistance values assumes exposed pad is soldered (or equivalent) to the device's most negative potential on the PCB. 4. Output loaded with 50 to VCC-2V. 5. VIN = VIL(min) or VIH(max) 6. VIHCMR (Min) varies 1:1 with VEE, (max) varies 1:1 with VCC.
