ADCLK905BCPZ-R7

Clock Buffers, Drivers Overview

The ADCLK905BCPZ-R7 is an ultrafast clock and data buffer fabricated on Analog Devices' proprietary XFCB3 silicon germanium (SiGe) bipolar process. It features a single differential input and a single differential output, supporting ECL, PECL, and NECL logic families. The device provides a typical propagation delay of 95 ps and supports toggle rates up to 7.5 GHz with a 10 Gbps data rate capability. It incorporates on-chip center-tapped 100 Ω input termination resistors and a VREF pin for AC-coupled input biasing. The buffer operates within a supply voltage range of 2.375 V to 3.63 V and is housed in a 16-lead LFCSP package.

Clock Buffers, Drivers Feature Summary

• Ultrafast SiGe performance with 95 ps typical propagation delay and 7.5 GHz toggle rate
• Low random jitter specification of 60 fs rms
• Integrated 100 Ω center-tapped input termination resistors
• Supports full-swing ECL outputs driving 800 mV into 50 Ω loads

Clock Buffers, Drivers Applications

• Clock and data signal restoration and level shifting
• Automated test equipment (ATE)
• High-speed instrumentation and line receivers
• Converter clocking and threshold detection

Clock Buffers, Drivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm packaging configuration. The R7 suffix indicates Tape & Reel packaging, while other suffixes such as WP or R2 denote different handling formats. Ensure that the RoHS compliance status matches the project requirements, as indicated by the Z suffix in the base part number.

Clock Buffers, Drivers Selection Notes

Select this component when low jitter and high-speed signal integrity are critical. The device requires proper transmission line termination referenced to VCC − 2 V to achieve specified performance. Designers must ensure adequate bypassing with low-inductance capacitors near power pins to maintain stability at frequencies up to 7.5 GHz.

Clock Buffers, Drivers Part Context

This part belongs to the ADCLK905/ADCLK907/ADCLK925 family of ultrafast buffers. While the ADCLK905 offers one input and one output, the ADCLK907 provides dual channels, and the ADCLK925 fans out one input to two outputs. All variants share the same 16-lead LFCSP package and core SiGe technology specifications.
