Overview
The ADCLK846BCPZ, produced by Analog Devices Inc., is a high-performance clock fanout buffer designed for low jitter and low power operation. This device supports a wide range of output configurations, from 6 LVDS to 12 CMOS outputs, including combinations of both LVDS and CMOS outputs. The clock input is versatile, accepting various single-ended and differential logic levels such as LVPECL, LVDS, HSTL, CML, and CMOS. The device features a sleep mode enabled by the SLEEP pin, allowing it to power down when not in use. It is packaged in a 24-pin LFCSP (4mm x 5mm) and operates over the standard industrial temperature range of −40°C to +85°C.
