What this 4.8 GHz clock buffer does for your clock tree
The ADCLK948BCPZ-REEL7 is a 2:8 fanout buffer and multiplexer from Analog Devices' SiGe series, handling clock distribution up to 4.8 GHz. It accepts CML, CMOS, LVDS, or LVPECL inputs and delivers LVPECL outputs, making it a single-chip interface between different logic families in a high-speed clock tree. The 2:8 input-to-output ratio lets you select one of two clock sources and distribute to eight destinations — useful for redundant clock architectures or splitting a reference across multiple ADC/DAC channels.
Supply voltage tolerance and temperature range
The part operates from 2.97V to 3.63V — a 3.3V nominal rail with 10% margin. Differential input and output paths reject common-mode noise, which is critical when routing clock signals across a noisy PCB or through a backplane.
Active production and sourcing posture
Analog Devices lists the ADCLK948BCPZ-REEL7 as Active and ROHS3 compliant. The 32-LFCSP (5x5) package has an exposed pad that must be soldered to a thermal land on the PCB for heat dissipation.
