ADN4670BCPZ

Clock Buffers, Drivers Overview

The ADN4670BCPZ 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, an additive phase jitter of 281 fs rms at 30.72 MHz, and a supply current of 35 mA with all outputs tristated. It is housed in a 32-lead LFCSP package.

Clock Buffers, Drivers Feature Summary

• Expands one differential clock input to 10 LVDS outputs with <30 ps typical output skew.
• Programmable serial interface allows selection of CLK0 or CLK1 and individual output enable/disable.
• Supports signaling rates up to 1.1 GHz with 2.375 V to 2.625 V power supply range.
• I/O pins are fail-safe during power-down (VDD = 0 V).

Clock Buffers, Drivers Applications

• Clock distribution networks
• High-speed digital systems requiring low skew clock expansion

Clock Buffers, Drivers Procurement Notes

Verify the specific ordering suffix for packaging configuration. The ADN4670BCPZ designation corresponds to the tube/tray package option, while the -REEL7 suffix indicates tape and reel packaging. Confirm RoHS compliance status as indicated by the 'Z' suffix in the part number. Ensure the procurement source provides valid traceability documentation for the component.

Clock Buffers, Drivers Selection Notes

Select this component when a single differential clock source needs to drive multiple LVDS loads with minimal skew. The ADN4670BCPZ requires a 2.375 V to 2.625 V supply voltage. Designers must account for the 35 mA quiescent current and higher dynamic current when all outputs are enabled. The 32-LFCSP package requires appropriate thermal management considerations due to its exposed pad design.

Clock Buffers, Drivers Part Context

The ADN4670BCPZ belongs to the ADN4670 series of LVDS clock drivers from Analog Devices. It is functionally identical to the ADN4670BSTZ but utilizes a 32-lead Lead Frame Chip Scale Package (LFCSP) instead of the Low Profile Quad Flat Package (LQFP). Both variants share the same electrical specifications and industrial temperature range (-40°C to +85°C).

Clock Buffers, Drivers Replacement Considerations

The ADN4670BSTZ serves as a direct pin-compatible alternative within the same family, differing only in the LQFP package format. No other cross-model substitutes are documented in the provided data.
