SY100EP16V

NOT RECOMMENDED FOR NEW DESIGNS SY100EP16V 3.3V/5V Precision ECL Differential Receiver/Driver General Description The SY100EP16V is a 3.3/5V, 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 applications, an integrated voltage reference (VBB) is provided to bias for either single-ended use or for DC biasing when AC coupling to the device. The VBB pin should be used only as a bias for the SY100EP16V 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 SY100EP16V operates from a 3.3V or 5V ±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.
