ADCLK946BCPZ

Clock Buffers, Drivers Overview

The ADCLK946BCPZ is a SiGe clock fanout buffer featuring six LVPECL outputs. It operates at frequencies up to 4.8 GHz with a maximum propagation delay of 220 ps. The device accepts differential inputs including CML, CMOS, LVDS, and LVPECL, utilizing on-chip 100 Ω termination resistors. Powered by a 3.3 V supply (range 2.97 V to 3.63 V), it delivers low jitter performance with 75 fs rms broadband random jitter. Housed in a 24-lead LFCSP package, it functions within an industrial temperature range of -40°C to +85°C.

Clock Buffers, Drivers Procurement Notes

Verify the specific ordering suffix when sourcing components. The ADCLK946BCPZ designation indicates a RoHS-compliant part supplied in a tray format. Confirm that the procurement channel provides the correct package option (CP-24-14) and temperature grade (-40°C to +85°C) to ensure compatibility with the intended application requirements.

Clock Buffers, Drivers Selection Notes

Select this component for high-speed applications requiring low added jitter and flexible input compatibility. Ensure the PCB layout supports the exposed paddle connection to VEE for thermal management and electrical grounding. Verify that the receiving buffers match the LVPECL output voltage levels or utilize appropriate termination schemes such as Y-termination or Thevenin equivalents for proper signal integrity.

Clock Buffers, Drivers Part Context

The ADCLK946BCPZ belongs to the ADCLK946 series of ultrafast clock fanout buffers fabricated on Analog Devices' proprietary XFCB3 silicon germanium bipolar process. It serves as a distribution element for high-frequency clock signals, offering six full-swing ECL output drivers designed to drive transmission lines directly.
