GENERAL DESCRIPTION

The ADCLK948 is an ultrafast clock fanout buffer fabricated

on the Analog Devices, Inc., proprietary XFCB3 silicon german-

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

speed applications requiring low jitter.

V 1

CLK1

The device has two selectable differential inputs via the IN_SEL

control pin. Both inputs are equipped with center tapped,

differential, 100 Ω on-chip termination resistors. The inputs

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

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

IN_SEL

REFERENCE

REF

_REFx pin is available for biasing ac-coupled inputs.

Figure 1.

The ADCLK948 features eight 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 output stages are designed to directly drive 800 mV each

side into 50 Ω terminated to V_CC− 2 V for a total differential

output swing of 1.6 V.

The ADCLK948 is available in a 32-lead LFCSP and specified

for operation over the standard industrial temperature range of

−40°C to +85°C.
