I completed the datasheet cross-check and created the detailed review report; the symbol and footprint match the datasheet, with only metadata/pin-description quality issues flagged.
Summary: the part metadata, 4-pad pinout, and 9×14 mm SMD footprint match the Crystek CCHD-957 datasheet; remaining cleanup items are metadata quality only — stable PDF datasheet URL, pin electrical types/descriptions, and manufacturer normalization to Crystek Corporation.
