Three tiers: SY-1231 cabinet NTP (BeiDou+GPS · TCXO · Up to 3840 · Accuracy ±1–5 ms) → SY-4096 half-width 1U stamp+OCXO+hardware time I/O (Up to 21,000 · sustained 20,000–21,000 · Accuracy ≤ 100 µs) → SY-8640 multi-port / dual supply (roadmap). Match scenario first.

Pick one SKU first

Two deliverable SKUs: cabinet software-stamp NTP, or half-width hardware-stamp NTP. Not a PTP grandmaster. Every figure carries lab conditions.

SY-8640 is the multi-port / dual-supply path—no commitment figures on this table.

1231 vs 4096: one honest line-up

Client count is always N=⌊η×R/f_poll⌋. We do not print η or treat throughput as a measured client count. NIC figures ≠ 1PPS.

TemporaSync™ SY-1231

SY-1231-BG-T-S

Cabinet GNSS LAN NTP Stratum 1. BeiDou+GPS discipline, TCXO holdover, single 10/100M port, plus Modbus / TTL 1PPS / minute PULSE. No IRIG, dual NIC, or dual PSU. Up to 3840 NTP requests per second; Accuracy ±1–5 ms.

Fit Hospital weak-current, industrial cabinets, security NVR, office/metrology; single LAN port. Planning N=⌊η×R/f_poll⌋.

Not for Hardware-stamped NTP / OCXO / IRIG-B (see SY-4096); or separated mgmt/timing ports, multi-gigabit, dual supply (see SY-8640).

TemporaSync™ SY-1231 1U chassis front panel

Shipping cabinet SKU. Delivers Stratum 1 after lock: single port, BeiDou+GPS, TCXO; Web and SNMP read-only for checks. Typical fit: hospital weak-current, industrial cabinets, security subnets. How it differs from the other model

TemporaSync™ SY-4096

SY-4096-GN-O-S

Half-width 1U · single-port Web ops. Hardware-stamped NTP, OCXO, 1PPS / IRIG-B DCLS / programmable pulse / Modbus. NTP Support: Up to 21,000 req/s (sustained 20,000–21,000); Accuracy ≤ 100 µs.

Fit Factory, campus, and building-edge cabinets that need stamped NTP, OCXO, and hardware time I/O on one subnet.

Not for Cabinet TCXO / lower cost → SY-1231. Multi-port or dual supply → SY-8640.

TemporaSync™ SY-4096 half-width 1U chassis front panel

Adds on-chip IEEE 1588 hardware-timestamped NTP, OCXO, and IRIG-B DCLS versus SY-1231, plus BNC 1PPS and a programmable pulse on a path separate from Ethernet stamps. Both have RS-485 Modbus. Still one Ethernet port. Up to 21,000 NTP requests per second (sustained 20,000–21,000); Accuracy ≤ 100 µs (network NTP, ≠ 1PPS). Planning N=⌊η×R/f_poll⌋. How it differs from the other model

TemporaSync™ SY-8640

SY-8640-GN-O-S Roadmap

Plant / multi-port path: separable mgmt/timing, multi-gigabit, optional dual supply. Planned direction only until the shipping datasheet—no standalone commitment figures.

Fit Power/metals plants needing separated mgmt/timing or multi-port form (roadmap); bridge with SY-1231 / SY-4096.

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

Planned flagship path. vs SY-4096: multi-port, dual supply, plant tenders. Do not tender against unpublished items.
