Comment les pièces KCCS OCXO, GPSDO, VCXO et rubidium se mappent sur les empreintes Microchip, Oscilloquartz, Rakon et IQD — avec un rapport de cross-référencement gratuit.
Designers at North American and European OEMs have, for a decade or more, specified oscillators from Microchip (formerly SiTime's quartz line and the acquired Oscilloquartz), Rakon, IQD Frequency Products, FeiZhou and Frequency Electronics. Today two pressures push engineering teams to evaluate a second source: long lead times from the incumbents (often 16–26 weeks) and cost reduction programs after component qualification. KCCS has built its quartz and disciplined oscillator families around the packages and performance levels these western parts occupy, so a second source is usually a drop-in — not a redesign.
| Incumbent Family | Package / Class | KCCS Equivalent Family | Typical Match |
|---|---|---|---|
| Oscilloquartz OCXO (8600 / 8607 / 8608) | DIP 14×9 / 25×25, ultra-low ADEV | KONS450 / KONS350 / KONS327 | ADEV 8E-14 @10s, pin-out compatible |
| Microchip / Saftime GPSDO | 1PPS-disciplined module | KDO65 / KDO27 | ±1.5 μs/24h holdover, 10 MHz sine |
| Rakon OCXO / TCXO (NT Series) | SMD 14×9, 20×20, 25×25 | KOT22 / KOM09 / KT05 | ±0.1–0.5 ppb, same footprint |
| IQD VCXO / OCXO | SMD 7050 / 1409 | KV09 / KOM05 | Pulling range ±20 ppm, same outline |
| FEI / FEI Rubidium | 10 MHz rubidium standard | KRA50 / KRA76 | Aging ≤1.5E-12/day, same output |
Nous ne promettons pas « identique » sans avoir vu le datasheet actuel. Certaines pièces occidentales ont des courbes de trimage propriétaires, des formes d'onde de sortie custom ou un criblage militaire qui exigent un accord d'ingénierie explicite. Envoyez-nous la référence et nous vous dirons honnêtement si un drop-in existe ou si un petit redesign est requis.
