SY10/100EP16U 2.5/3.3V Precision ECL Differential Receiver/Driver General Description The SY10/100EP16U is a 2.5/3.3V, high-speed, fully differential ECL Receiver/Driver that can process clock signals as fast as 3GHz or data patterns up to 2.5Gbps. The differential input includes an internal 75kΩ pulldown resistor on both the true and complement inputs and a 37.5kΩ pull-up resistor in the complement input only. For AC-coupled input interface and single-ended applications, an integrated voltage reference (VBB) is provided. Single-ended CLK input operation is limited to VCC ≥ 3.0V in PECL mode, or VEE ≤ -3.0V. The VBB pin should be used only as a bias for the SY10/100EP16U since its current sink/source capability is limited. Whenever used, the VBB pin should be bypassed to the most positive supply voltage. The output is 800mV ECL, with fast rise/fall times guaranteed to be less than 200ps. When the inputs are left open, the internal input clamps will force the Q output low. The SY10/100EP16U operates from a 2.5V ±5% or 3.3V ±10% supply and is guaranteed over the full industrial temperature range (–40°C to +85°C). The SY100EP16V is part of Micrel’s high-speed, Precision Edge® product line. Datasheets and support documentation can be found on Micrel’s web site at: www.micrel.com.

SY10/100EP16U Pin Description Pin Number Pin Name 2, 3 D, /D ECL Inputs. The D input has an internal 75kΩ pull-down resistor and the /D has an internal 37.5kΩ pull-up and a 75kΩ pull-down resistor. 7, 6 Q, /Q ECL Outputs. Terminate with 50Ω to VCC -2V. See “Output Interface Applications” section for more details. 4 VBB Reference Output Voltage: This reference is typically used to bias the unused inverting input for single-ended input applications, or as the termination point for AC-coupled differential input applications. VBB reference value is approximately VCC- 1.42V, and tracks VCC 1:1. Maximum sink/source capability for VBB is 0.50mA. For single ended inputs, connect to the unused input through a 50Ω resistor. Decouple the VBB pin with a 0.01µF capacitor to VCC. 8 VCC Positive Power Supply: Bypass with 0.1µF//0.01µF low ESR capacitors as close to the VCC pin as possible. 5 VEE Negative Power Supply: VEE and exposed pad must be tied to the most negative supply. ® Exposed pad is available for 8-pin MLF package only.
