GENERAL DESCRIPTION
The ADCLK948 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 ADCLK948 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 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
VREFx pin is available for biasing ac-coupled inputs.

The ADCLK948 features eight full-swing emitter coupled logic
(ECL) output drivers. For LVPECL (positive ECL) operation,
bias VCC to the positive supply and VEE to ground. For ECL
operation, bias VCC to ground and VEE to the negative supply.

The output stages are designed to directly drive 800 mV each
side into 50 Ω terminated to VCC 2 V for a total differential
output swing of 1.6 V.
