The ADCLK914BCPZ-WP is an ultrafast clock/data buffer fabricated onthe Analog Devices, Inc., proprietary, complementary bipolar(XFCB-3) silicon-germanium (SiGe) process. The ADCLK914features high voltage differential signaling (HVDS) outputssuitable for driving the latest Analog Devices high speed digitalto-analogconverters (DACs). The ADCLK914BCPZ-WP has a single,differential open-collector output.
The ADCLK914BCPZ-WP buffer operates up to 7.5 GHz with a 160 pspropagation delay and adds only 110 fs random jitter (RJ).The input has a center tapped, 100 Ω, on-chip terminationresistor and accepts LVPECL, CML, CMOS, LVTTL, or LVDS(ac-coupled only). A VREF pin is available for biasing ac-coupledinputs.
The HVDS output stage is designed to directly drive 1.9 V eachside into 50 Ω terminated to VCC for a total differential outputswing of 3.8 V.
The ADCLK914BCPZ-WP is available in a 16-lead LFCSP. It is specifiedfor operation over the extended industrial temperature range of−40°C to +125°C.
