ADN4670BSTZ-REEL7

Clock Buffers, Drivers Overview

The ADN4670BSTZ-REEL7 is a low voltage differential signaling (LVDS) clock driver manufactured by Analog Devices Inc. It expands one differential clock input to ten LVDS outputs, supporting signaling rates up to 1.1 GHz. The device operates on a 2.375 V to 2.625 V supply and features programmable selection between two differential inputs (CLK0 or CLK1) via a serial interface. Key electrical parameters include a typical output skew of less than 30 ps, a propagation delay of 3 ns, and a supply current of 35 mA with all outputs tristated. It is housed in a 32-lead LQFP package.

Clock Buffers, Drivers Feature Summary

• Expands one differential LVDS clock input to 10 differential LVDS outputs
• Programmable serial interface for input selection (CLK0/CLK1) and individual output enable/disable
• Low output skew (<30 ps typical) and high signaling rate up to 1.1 GHz
• Fail-safe I/O pins during power-down (VDD = 0 V)

Clock Buffers, Drivers Applications

• Clock distribution networks
• High-speed data acquisition systems
• Telecommunications equipment

Clock Buffers, Drivers Procurement Notes

Verify the specific ordering suffix REEL7 corresponds to the Tape & Reel packaging format as indicated in local product fields. Confirm RoHS compliance status through official manufacturer documentation, as the datasheet notes Z suffix indicates RoHS compliance but does not explicitly define the REEL7 suffix's environmental status beyond standard manufacturing practices.

Clock Buffers, Drivers Selection Notes

Select this component when a single differential clock source needs to drive multiple LVDS loads with minimal skew. Ensure the system design accommodates the 2.375 V to 2.625 V supply voltage range. Verify that the PCB layout supports the 32-LQFP package dimensions and provides adequate thermal dissipation, given the junction temperature maximum of 150°C and thermal impedance of 59°C/W.

Clock Buffers, Drivers Part Context

The ADN4670BSTZ-REEL7 belongs to the ADN4670 series of LVDS clock drivers. It is functionally equivalent to the ADN4670BCPZ variants but utilizes a 32-lead Low Profile Quad Flat Package (LQFP) instead of the Lead Frame Chip Scale Package (LFCSP). Both packages offer identical electrical performance and pinouts within the industrial temperature range of -40°C to +85°C.

Clock Buffers, Drivers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Direct replacements must match the 1:10 LVDS fanout configuration, 1.1 GHz speed, and 32-lead LQFP package constraints.
