The Enable is synchronous so that the outputs will only be enabled/disabled when they are already in the LOW state. This avoids any chance of generating a runt clock pulse when the device is enabled/disabled as can happen with an asynchronous control. When this device is used as a clock fanout, disabling the downstream clock may reduce system power. The SY54020AR can process clock signals as fast as 3.2 GHz or data patterns up to 3.2Gbps. The differential input includes Micrel’s unique, 3-pin input termination architecture that interfaces to LVPECL, LVDS or CML differential signals as small as 100mV (200mVpp) without any level-shifting or termination resistor networks in the signal path. For AC-coupled input interface applications, an internal voltage reference is provided to bias the VT pin. The outputs are CML, with extremely fast rise/fall times guaranteed to be less than 100ps. The SY54020AR operates from a 2.5V ±5% core supply and a 1.2V, 1.8V or 2.5V ±5% output supply and is guaranteed over the full industrial temperature range (– 40°C to +85°C).
