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 V
BB
reference for single-
ended AC-coupling applications. Whenever used, the V
BB
pin should be bypassed to ground via a 0.01µF capacitor.
V
BB
reference can only sink/source 0.5mA.
Under open input conditions (pulled to V
EE
), internal
input clamps will force the Q output LOW.

Type
100k ECL Input
Pin Function
Differential PECL/ECL Input: The signal inputs include internal 75kΩ pull-
down 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 0.1µF//0.01µF low ESR capacitors.
Negative Power Supply: V
EE
and exposed pad must be tied to most
negative supply. For PECL/LVPECL connect to ground.
Bias Voltage: V
CC
–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.
