ADN4670BSTZ

Clock Buffers, Drivers Overview

The ADN4670BSTZ 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 within a supply voltage range of 2.375 V to 2.625 V and features an industrial temperature range from -40°C to +85°C. Key electrical specifications include a typical output skew of less than 30 ps, a propagation delay of 3 ns, and a maximum additive phase jitter of 111 fs rms at 125 MHz. It is housed in a 32-lead Low Profile Quad Flat Package (LQFP).

Clock Buffers, Drivers Feature Summary

• Expands a single differential clock input to 10 LVDS outputs with low skew (<30 ps typ).
• Programmable via serial interface to select between two clock inputs (CLK0/CLK1) and enable/disable individual outputs.
• Supports data rates up to 1.1 GHz with ±100 mV differential input threshold.
• Fail-safe I/O pins during power-down (VDD = 0 V).

Clock Buffers, Drivers Applications

• Clock distribution networks

Clock Buffers, Drivers Procurement Notes

Verify the package type matches the design requirements, as the ADN4670 series includes both LFCSP and LQFP options. Confirm RoHS compliance status for the specific batch. Check lead times and availability through authorized distributors, as supply levels may vary. Ensure ESD precautions are followed during handling due to the sensitivity of CMOS inputs.

Clock Buffers, Drivers Selection Notes

Select the ADN4670BSTZ when a 32-lead LQFP package is required instead of the LFCSP variant. Verify that the system requires a 1:10 fanout buffer with programmable output control. Ensure the operating environment stays within the -40°C to +85°C industrial temperature range. Confirm compatibility with 50 Ω transmission line environments and 2.5 V logic levels for programming inputs.

Clock Buffers, Drivers Part Context

The ADN4670BSTZ belongs to the ADN4670 family of LVDS clock drivers. It shares core functionality with the ADN4670BCPZ but differs in packaging. The BSTZ suffix indicates the 32-lead Low Profile Quad Flat Package (ST-32-2), whereas the BCPZ uses a 32-Lead Lead Frame Chip Scale Package (CP-32-7). Both variants offer identical electrical performance and pinouts where applicable.

Clock Buffers, Drivers Replacement Considerations

The ADN4670BCPZ is a direct functional substitute with an identical pinout and electrical specification, differing only in the LFCSP package form factor. No other cross-model substitutes are documented in the provided datasheet.
