SY-1231
Typical order: SY-1231-BG-T-S
Applications: hospital weak-current, industrial cabinets, security NVR, and auxiliary metrology timing on a single LAN.
Features: GNSS-disciplined NTP Stratum 1 after lock; BeiDou + GPS; TCXO holdover; Modbus / TTL 1PPS / PULSE (minute PPM); Web + SNMP read-only. No IRIG, no OCXO.
Fit: single-port 10/100M cabinet deployments. Capacity and protocol scope are in the datasheet.
Not for: hardware-stamped NTP / OCXO / hardware time I/O (see 3500) or separated mgmt/timing multi-gigabit dual-supply (see 4000).
Coming soon
SY-4096
Typical order: SY-4096-GN-O-S
Applications: factory, campus, and building-BA edge cabinets needing half-width 1U Stratum 1 with industrial time outputs.
Features: IEEE 1588 hardware-timestamped NTP; OCXO holdover; hardware 1PPS / IRIG-B / programmable pulse (edge-aligned).
Fit: edge upgrade path aligned with datasheet v1.3; reply capacity ≥13,000 req/s. Plan clients with N=⌊ηR/f⌋, η=0.85. Does not replace the multi-port flagship.
Not for: immediate cabinet stock delivery—cover with SY-1231; multi-port / dual-supply plant tenders → 4000.
Planned
SY-8640
Typical order direction: SY-8640-GN-O-S
Applications: power and metals plants, SIS companion rooms, and denser deployments needing multi-port density or dual supply.
Features (planned): multi-gigabit ports with separable management and timing; optional OCXO; NTP-first with PTP as a planned option.
Fit: roadmap for denser plant rooms. Specs below are not contractual until a shipping datasheet is published.
Not for: immediate cabinet delivery contracts—cover with SY-1231; half-width stamp + hardware time I/O → 3500.
