GENERAL DESCRIPTION

Figure 1.

The ADCLK946 is an ultrafast clock fanout buffer fabricated on

the Analog Devices, Inc., proprietary XFCB3 silicon germanium

(SiGe) bipolar process. This device is designed for high speed

applications requiring low jitter.

The device has a differential input equipped with center-tapped,

differential, 100 Ω on-chip termination resistors. The input accepts

dc-coupled LVPECL, CML, 3.3 V CMOS (single ended), and

ac-coupled 1.8 V CMOS, LVDS, and LVPECL inputs. A V_REFpin

is available for biasing ac-coupled inputs.

The ADCLK946 features six full-swing emitter-coupled logic

(ECL) output drivers. For LVPECL (positive ECL) operation,

bias V_CCto the positive supply and V_EEto ground. For ECL

operation, bias V_CCto ground and V_EEto the negative supply.

The ECL output stages are designed to directly drive 800 mV

each side into 50 Ω terminated to V_CC− 2 V for a total differen-

tial output swing of 1.6 V.

The ADCLK946 is available in a 24-lead LFCSP and is specified

for operation over the standard industrial temperature range of

−40°C to +85°C.
