Can we tender SY-8640 against a shipping datasheet?

No. The shipping datasheet is not published yet. Page content is directional planning only—contract against the formal datasheet when available. Bridge with SY-1231 or 4096.

When should we wait for the 8640?

Power/metals plants that need separated management and timing ports, multi-gigabit links, dual supply, or higher capacity. Single-subnet cabinet NTP → 1231; single-port stamp+OCXO+IRIG → coming 4096.

May we put PTP or unpublished throughput into an RFQ?

No. The line is NTP-first; PTP is a planned/contractual option. Until the shipping datasheet, throughput or nanosecond Ethernet figures are not contractual.

TemporaSync™

SY-8640

NTP Time Server · Stratum 1

Typical order model: SY-8640-GN-O-S Roadmap

Nameplate: TemporaSync · SY-8640

For power and metals plants and half-rack rooms: multi-gigabit ports with separable management and timing, optional OCXO, NTP-first with PTP as a planned option.

Fit Power/metals plants, SIS companion, separated mgmt/timing or half-rack form (roadmap); bridge with 1231/4096.

Not for Immediate cabinet delivery contracts (use SY-1231; half-width 1U stamp + hardware time I/O → 4096).

Selection help Download datasheet How to choose

Flagship path (in development). vs 4096: multi-port, half-rack, hundreds-of-clients class for plant half-rack and multi-port tenders. Planned direction only until the shipping datasheet.

How it differs from the other model

8640 is 86400 s/day without the trailing zero (24×360)—flagship time-origin name. Do not tender unpublished items. Below: SY-1231 protocol, SY-4096 cabinet capacity. Reserved next: SY-16384.

Specification summary

Role	Multi-port / half-rack flagship path; form-factor and port upgrade vs SY-4096
Form factor direction	Half-width 1U / rackable; multiple physical ports (mgmt/timing separable)
Constellation (order code GN)	Multi-constellation GNSS (module-dependent; BeiDou emphasized)
Oscillator options	T=TCXO / O=OCXO; power S/D
Timing direction	NTP-first; PTP and related options are planned/contractual paths—follow the shipping datasheet
Management direction	Cabinet Web + SNMP; HTTPS / SNMPv3 as contract options
Capacity direction	Hundreds of LAN clients class (no inflated throughput marketing)

Interfaces

Multi Ethernet (planned)
Timing I/O (PPS / IRIG, planned)
