Microchip Technology

The SY10/100EP11U is a precision, high-speed 1:2 differential fanout buffer. Having within-device skews and output transition times significantly improved over the EL11V, the EP11U is ideally suited for those applications which require the ultimate in AC performance.The differential inputs of the EP11U employ clamping circuitry to maintain stability under open input conditions. If the inputs are left open, the Q outputs will go LOW.

The SY10EP51V is a D flip-flop with reset and differential clock. The device is pin and functionally equivalent to the EL51 device.The reset input is an asynchronous, level triggered signal. Data enters the master portion of the flip-flop when CLK is LOW and is transferred to the slave, and thus the outputs, upon a positive transition of the CLK. The differential clock inputs of the EP51V allow the device to be used as a negative edge triggered flip-flop.The differential input employs clamp circuitry to maintain stability under open input conditions. When left open, the CLK input will be pulled down to VEE and the /CLK input will be biased a VCC/2.

The SY54017R is a fully differential, low voltage 1.2V/1.8V CML 2:1 MUX with Fail Safe Inputs. The SY54017R can process clock signals as fast as 2.5GHz 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, (AC- or DC-coupled from a 2.5V driver) 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 95ps.The SY54017R operates from a 2.5V ±5% core supply and a 1.8V or 1.2V ±5% output supply and is guaranteed over the full industrial temperature range (-40°C to +85°C). The SY54017R is part of Micrel's high-speed, Precision Edge® product line.

The SY54020R is a fully differential, low voltage 1.2V/1.8V/2.5V CML 1:4 Fanout Buffer with active-low Enable (/EN) and Fail-Safe Input (FSI). 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. FSI is a special circuit designed to sense the amplitude of the input signal and to latch the output when an invalid or no signal is present at the input. The SY54020R can process clock signals up to 2.5 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.

The SY54023R is a fully differential, low voltage 1.2V/1.8V CML 2x2 Crosspoint Switch with Fail Safe Inputs.
