ADCLK907BCPZ-R7

Clock Buffers, Drivers Overview

The ADCLK907BCPZ-R7 is a dual 1:1 ultrafast clock and data buffer fabricated on Analog Devices' proprietary XFCB3 silicon germanium (SiGe) bipolar process. It features two independent channels, each providing full-swing emitter coupled logic (ECL) output drivers capable of supporting a 7.5 GHz toggle rate and 10 Gbps data rate. The device exhibits a typical propagation delay of 95 ps and 60 fs random jitter. Inputs include center-tapped, 100 Ω on-chip termination resistors with a VREF pin for biasing AC-coupled signals. It operates within a supply voltage range of 2.375 V to 3.63 V and functions across an extended industrial temperature range of −40°C to +125°C in a 16-lead LFCSP package.

Clock Buffers, Drivers Feature Summary

• Converter clocking systems

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 and reel packaging. Confirm RoHS compliance status as indicated by the Z suffix in the base part number. Ensure the procurement source provides valid traceability for the SiGe bipolar process fabrication.

Clock Buffers, Drivers Selection Notes

Select this component when dual-channel ECL buffering with minimal added jitter is required. The ADCLK907 provides two isolated 1:1 buffers, unlike the single-channel ADCLK905 or the 1:2 fanout ADCLK925. Ensure the design supports the specified 2.375 V to 3.63 V supply range and utilizes proper transmission line termination techniques to achieve the stated 95 ps propagation delay and 60 fs RJ performance.

Clock Buffers, Drivers Part Context

The ADCLK907 belongs to the ADCLK905/ADCLK907/ADCLK925 family of ultrafast SiGe ECL buffers. All three devices share the same 16-lead LFCSP package and core technology but differ in channel configuration. The ADCLK907 specifically offers two independent 1:1 buffering paths, making it suitable for applications requiring simultaneous processing of two distinct clock or data streams with identical timing characteristics.

Clock Buffers, Drivers Replacement Considerations

Public confirmed substitutes include ADCLK905BCPZ-R7 for single-channel requirements and ADCLK925BCPZ-R7 for 1:2 fanout applications. These parts share the same package and electrical specifications but differ in internal circuit topology.
