FFF CompatibilityFeatures the exact same 40-pin VQFN (6x6mm) package with identical pin assignments and footprint compatibility.Housed in the identical 40-pin VQFN (Q4) package matching all mechanical dimensions and mounting characteristics.Performs the same direct-conversion receiver function while providing enhanced electrical performance, faster transients, and lower power.Uses a larger 48-pin VQFN package instead of the 40-pin VQFN, requiring a complete PCB land pattern redesign.The physical dimensions and pin count are different (48-pin VQFN vs. 40-pin VQFN).Employs a dual-superheterodyne architecture instead of direct conversion, requiring changes in baseband and LO planning.
AI Summary

CMX994EQ4 by CML Micro: - RF Receiver 50MHz ~ 1.218GHz -116dBm 19.2kbps PCB, Surface Mount 40-VQFN (6x6).

The CMX994EFQ4 is the official, active manufacturer-recommended direct replacement for the obsolete CMX994EQ4, offering superior performance in the same footprint.

  • Official manufacturer-recommended direct replacement for legacy CMX994EQ4
  • Fully pin-to-pin compatible drop-in replacement with no PCB redesign required
  • Improved power-up/down transient response allowing faster switching in TDMA systems

The CMX992Q3 is a functional alternative from the same manufacturer that covers a similar frequency range but uses a dual-superheterodyne architecture rather than direct conversion.

  • Alternative receiver IC from the same manufacturer covering a similar 100 MHz to 1 GHz frequency range
  • Highly integrated solution with built-in LNA, mixers, and IF PLL
  • Requires a complete schematic and PCB layout redesign
  • Uses a dual-superheterodyne architecture which requires different external filtering compared to direct-conversion zero-IF

You searched one part. Parter watches your whole BOM.

  1. All your BOM, at once

    Parter maps every line to live stock, lead time, lifecycle and compliance data across the entire market — not part by part.

  2. Hear about problems before they hit production

    Allocation, EOL and last-time-buy notices surface the moment they appear, not when your buyer's PO bounces.

  3. Qualified replacements in minutes, not days

    Every at-risk line gets form-fit-function matches like the ones above — deltas flagged, evidence attached. Review, push to your BOM, and Parter starts watching the new part too.
