Product details

Clock generator — what this part is and where it fits

The Texas Instruments CDC9843DW is a clock generator IC, a timing device that produces one or more clock signals from a reference input. Clock generators are used in digital systems where multiple synchronous clock domains are needed — think networking equipment, base stations, data converters, and FPGA-based designs that require clean, low-jitter clocks. One constraint to note: the CDC9843DW is RoHS non-compliant, so it contains lead (Pb) in the solder finish or die attach. That rules it out for lead-free assembly lines under RoHS exemptions unless your process explicitly allows legacy tin-lead soldering.

Bulk packaging — what it means on the line

For a pick-and-place machine, that requires a tube feeder or tray handler; for hand-assembly or rework, it is straightforward.

Sourcing and lifecycle — active, but with a compliance catch

The RoHS non-compliant status is the main sourcing consideration: if your BOM requires full RoHS compliance (lead-free), this part will not pass incoming inspection. For legacy designs with tin-lead soldering, it is a direct fit.

Frequently asked questions

Is CDC9843DW RoHS compliant?

No, the CDC9843DW is RoHS non-compliant, so it contains lead and is not suitable for lead-free assembly lines.

What is the typical application of CDC9843DW?

As a clock generator, the CDC9843DW is used in digital systems requiring multiple synchronous clock domains — such as networking equipment, base stations, data converters, and FPGA-based designs.

What are the alternatives to CDC9843DW?

A functional alternative in a different package and technology is the CD74HCT7046AE, a phase-locked loop (PLL) from the 74HCT series. It operates at up to 38 MHz, uses a 4.5 V supply, and comes in a through-hole package. However, it is a PLL rather than a general clock generator, so verify the application fit before substituting.
