Part Datasheet Audit
Thought for 18 sec
I’ll audit the part metadata, source the official datasheet if needed, then verify the symbol, footprint, and pin descriptions against it and update the Datasheet property.
Worked for 2 mins 53 sec
Audit complete. The 4-pin symbol and footprint pin mapping and geometry match the Crystek CCHD-957 datasheet: 14.2 × 9.14 mm body, 1.27 × 2.28 mm pads, and pins 1=E/D, 2=GND, 3=OUT, 4=VCC.
Key issues
- Datasheet property exists, so it was not replaced; however, the stored Crystek HTTP URL is currently unavailable/404 and should eventually be changed to a stable manufacturer-hosted URL.
- Part Type is blank.
- Mount is incorrectly/generically listed as “Standard”; it should indicate SMD/SMT.
- All symbol pins have Unspecified electrical type and no meaningful pin descriptions.
- Description is broadly correct but omits “ultra-low phase-noise HCMOS oscillator with standby mode.”
Key specs: 22.5792 MHz, 3.3 V ±0.3 V, ±25 ppm, 0°C to +70°C, HCMOS/15 pF, 25 mA maximum supply current, 3 ns maximum rise/fall time, and enable/disable standby input.
