ADCLK914BCPZ-WP

Clock Buffers, Drivers Overview

The ADCLK914BCPZ-WP is an ultrafast clock and data buffer fabricated on a silicon-germanium process. It features a single differential open-collector output designed for high voltage differential signaling (HVDS). The device operates at frequencies up to 7.5 GHz with a typical propagation delay of 160 ps and adds only 110 fs of random jitter. It accepts LVPECL, CML, CMOS, LVTTL, or AC-coupled LVDS inputs via an internal 100 Ω termination. Powered by a 3.3 V supply, it functions within an extended industrial temperature range of −40°C to +125°C in a 16-lead LFCSP package.

Clock Buffers, Drivers Procurement Notes

Verify the specific ordering suffix to confirm packaging format. The -WP suffix indicates a waffle pack configuration, whereas -R7 denotes tape and reel. Confirm RoHS compliance status as indicated by the Z suffix in standard variants. Ensure procurement channels support the extended industrial temperature grade required for the application environment.

Clock Buffers, Drivers Selection Notes

Select this component when driving high-speed DACs requiring HVDS interfaces. Ensure the PCB layout supports low-inductance power planes and adequate bypassing near VCC and VEE pins. Verify that the input signal slew rate remains sufficient to maintain the specified 110 fs jitter performance. Account for the 100 mA typical supply current in thermal design calculations.

Clock Buffers, Drivers Part Context

This part belongs to the ADCLK914 series of ultrafast buffers. It is specifically engineered to interface standard logic levels to high-voltage differential outputs. The device serves as a critical link between clock generators and multi-GSPS data converters in demanding signal processing architectures.

Clock Buffers, Drivers Replacement Considerations

The ADCLK914BCPZ-R7 offers identical electrical specifications and functionality but utilizes a tape and reel packaging format instead of the waffle pack associated with the -WP suffix.
