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.","metaTitle":"CDC9843DW Clock Generator, Active, RoHS Non-Compliant","metaDescription":"CDC9843DW clock generator from Texas Instruments.

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."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/CDC9843DW","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/CDC9843DW when reusing this data.
