ACS9593T: ToPSync™ Timing-over-packet synchronization technology slave 1588 device
The ACS9593T utilizes Semtech's ToPSync™ technology which, in conjunction with an appropriate Precision Time Protocol (PTP) Grandmaster, can be used for many applications which require a reference frequency that is traceable to a remote, centralized, frequency source, or a time or phase reference that is aligned to a central reference point of phase or time.
All ToPSync products come with a full support package including:
- Datasheet
- User Guide
- Evaluation system
- Application schematics and layouts
- API driver code and messaging system with documentation
- PTP Network management GUI tool
- ToPSim network simulator and delay data analysis tool

Collapse All
- Fully integrated - IEEE1588 (PTP) Slave function providing reference frequency output. Time-of-Day (ToD) output and one pulse per second (PPS) output. Powerful integrated processor running clock recovery algorithm (a combination of PTP and adaptive packet delay filtering).
- PTP Grandmaster selection - configured or automatic (according to the PTP Best Master Clock algorithm). Multiple Grandmasters supported.
- Powerful network delay analysis delivers full time alignment over hostile networks (including Layer 2 and Layer 3 routing).
- Dynamic adaptation to delay variations. Tolerant to network loading changes (ramps and steps), routing changes and temporary outages.
- Operational support - unicast and multicast operation.
- Configurable DiffServ codepoint - for high priority packet routing.
- Precision holdover.
- Interfaces for:
- Time-aligned output pair: 1 PPS and 125 MHz divided by n (n = 4 to 125000).
- Frequency-aligned outputs: 1 Hz and programmable frequency 1 kHz to 62.5 MHz.
- Media Independent Interface (Ethernet port).
- Serial peripheral interface (SPI).
- SRAM port.
- Flash memory port.
- JTAG boundary scan port.
- Supports operation with a local oscillator accurate to ±20 ppm or better.
- Time alignment performance better than ±2 μs on a managed 5-switch GbE network under G.8261 test conditions.*
- Frequency alignment performance better than ±10 ppb on a managed 5-switch GbE network under G.8261 test conditions.*
- Standard compliance - IEEE 1588 v2, G.8261.
- BGA package - 300 pin, 19 mm x 19 mm, 1 mm pitch
- Lead-free RoHS and WEEE compliant
