What holdover is needed for a MiFID II / SEC-compliant trading timestamp?

Regulatory timestamps must stay within 100 microseconds of UTC for trades and 1 millisecond for order events. A KDO65-disciplined OCXO (±1.5 μs/24h holdover) gives comfortable margin even through multi-hour GNSS outages; pair with a KOS OCXO for the master reference for the lowest wander.

Will the oscillator survive GNSS jamming at a substation?

Yes — that is exactly what the disciplined oscillator architecture is for. During GNSS lock it tracks the satellite reference; during jamming it holds the KDO's calibrated frequency. The KDO65 class delivers sub-microsecond holdover across a full day.

Can KCCS modules be designed into my own PTP grandmaster?

Absolutely. We supply board-level OCXO, PLO and GPSDO modules with reference designs; our engineering team supports frequency plan, 1PPS mapping and thermal design. Send your block diagram through RFQ.

Do you supply low-power oscillators for data center and AI compute racks?

The KOP low-power OCXO (3.3 V, down to 23 mA steady-state) and KPLOSMA45 PLO are designed exactly for rack-mounted timing cards where heat and power density matter.

Why Microsecond Accuracy Decides Trade Routing

In co-located trading rooms and exchange matching engines, every packet timestamp is a regulatory and economic record. Regulators (SEC Rule 15c3-5, MiFID II clock-migration rules) require synchronized timestamps within 100 microseconds of UTC for trades, and within a millisecond for order events. The cheapest way to hit this on every server rack is a GPSDO / PTP grandmaster clock in the cage, and that grandmaster lives or dies by the stability of its internal oven oscillator.

Trading-floor integrators have historically chosen Microchip / Spectracom / Meinberg grandmasters with OCXO or rubidium internal references. KCCS supplies the OCXO and disciplined oscillator modules that go into these grandmasters and into in-house timing appliances — including the ultra-low ADEV KOS series for the master clock and the KDO series for satellite-disciplined remote nodes.

The Same Oscillator Class Runs the Smart Grid

Substation merging units, phasor measurement units (PMUs), and 5G wireless nodes on power-tower backhaul all need precise time for synchrophasors, fault location and wide-area control. A GPSDO with 1 μs/24h holdover survives GNSS jamming (a real risk at substations) without losing synchrophasor alignment. For distribution automation and FTTR-powered grid sensors, lower-cost TCXO and micro-disciplined modules carry the timing budget.
