ADCLK905BCPZ-R2

Clock Buffers, Drivers Overview

The ADCLK905BCPZ-R2 is an ultrafast clock and data buffer fabricated on Analog Devices' proprietary XFCB3 silicon germanium (SiGe) bipolar process. It features a single-ended differential input and a full-swing emitter coupled logic (ECL) output, supporting PECL, NECL, and CML configurations. The device provides a 1:1 buffering ratio with a maximum toggle rate of 7.5 GHz and supports data rates up to 10 Gbps. Key electrical specifications include a typical propagation delay of 95 ps, 60 fs random jitter, and a supply voltage range of 2.375 V to 3.63 V. It operates within an extended industrial temperature range of -40°C to +125°C and is housed in a 16-lead LFCSP package.

Clock Buffers, Drivers Feature Summary

• Ultrafast SiGe performance with 7.5 GHz toggle rate and 10 Gbps data capability
• Low jitter characteristics featuring 60 fs random jitter and 95 ps typical propagation delay
• Integrated 100 Ω center-tapped on-chip termination resistors at the differential inputs
• Flexible ECL output drivers designed for direct driving into 50 Ω terminated transmission lines

Clock Buffers, Drivers Applications

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

Clock Buffers, Drivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm packaging details. The R2 suffix indicates Tape & Reel packaging. Confirm RoHS compliance status as specified in the latest datasheet revision. Ensure the procurement channel sources directly from authorized distributors to guarantee component authenticity and traceability.

Clock Buffers, Drivers Selection Notes

Select this component when low jitter and high-speed signal integrity are critical requirements. The internal 100 Ω input termination simplifies interface design by eliminating external matching components. Verify that the application environment remains within the specified -40°C to +125°C operating temperature range. Ensure the power supply architecture can support the required VCC and VEE biasing conditions for the desired ECL logic family operation.

Clock Buffers, Drivers Part Context

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

Clock Buffers, Drivers Replacement Considerations

Direct functional substitutes within the same package and specification profile include the ADCLK907BCPZ-R2 and ADCLK925BCPZ-R2. These parts maintain identical pinouts and electrical characteristics but differ in the number of buffered channels.
