The ADCLK914 is an ultrafast clock/data buffer fabricated on
the Analog Devices, Inc., proprietary, complementary bipolar
(XFCB-3) silicon-germanium (SiGe) process. The ADCLK914
features high voltage differential signaling (HVDS) outputs
suitable for driving the latest Analog Devices high speed digitalto-analog
converters (DACs). The ADCLK914 has a single,
differential open-collector output.
The ADCLK914 buffer operates up to 7.5 GHz with a 160 ps
propagation delay and adds only 110 fs random jitter (RJ).
The input has a center tapped, 100 Ω, on-chip termination
resistor and accepts LVPECL, CML, CMOS, LVTTL, or LVDS
(ac-coupled only). A VREF pin is available for biasing ac-coupled
inputs.
The HVDS output stage is designed to directly drive 1.9 V each
side into 50 Ω terminated to VCC for a total differential output
swing of 3.8 V.
The ADCLK914 is available in a 16-lead LFCSP. It is specified
for operation over the extended industrial temperature range of
−40°C to +125°C.
