DP83630-EVK/NOPB 概要
Background Knowledge: An Ethernet PHY (physical layer transceiver) is the analog interface between a Media Access Controller (MAC) and the copper or fiber Ethernet cable. The PHY handles line coding, link training, and signal recovery at 10BASE-T or 100BASE-TX. The DP83630 family adds hardware timestamping of IEEE 802.1AS / IEEE 1588 packets so that distributed clocks across an industrial Ethernet network can be synchronized to within tens of nanoseconds, far better than software timestamping in a host processor. This makes the DP83630 the lowest PHY layer in the precision time distribution stack: PHY -> industrial Ethernet switch -> PTP-aware CPU -> application layer.
Key features of the DP83630-EVK/NOPB include the on-board DP83630 PHYTER IC, two RJ45 Ethernet jacks (one for the host MAC, one for the network), MII/RMII/SMII media-independent interfaces, JTAG and GPIO access, on-board 25 MHz reference oscillator, USB or barrel-jack power input, and pre-loaded demo firmware for transparent clock and ordinary clock PTP modes. The board is supported by TI's PHYTER software driver package and example Linux PTP daemon configurations.
Architecture: The underlying DP83630 die combines an IEEE 802.3-compliant 10/100 Ethernet PHY, an IEEE 1588 hardware timestamp unit with eight event timestamping channels, a SyncE clock multiplier, and TI's end-to-end transparent clock logic. The internal 1588 timestamp engine captures packet SFD (start-of-frame delimiter) times at the PHY rather than at the MAC, eliminating software jitter from interrupt latency and queueing delay. The EVK exposes all of these signals through header pins for oscilloscope probing and timing analysis.
Typical applications include industrial automation controllers, synchronized motion-control drives, IEC 61850 substation IEDs, IEEE 1588 grand-master and boundary clock reference designs, audio/video bridging (AVB) endpoints, smart-grid phasor measurement units, and test equipment for verifying PTP conformance. The kit's pre-stuffed DP83640 daughter board also lets engineers benchmark the DP83630 against the more feature-rich DP83640.
Design consideration: When using this EVK for IEEE 1588 benchmarking, power the board from a clean linear 3.3 V supply (the on-board LDO accepts 5 V USB) and connect the host MAC port directly to a PTP-aware processor or a dedicated test CPU. Avoid long MII/RMII traces between the EVK and the MAC, since PCB skew directly degrades timestamp accuracy.

主な用途
DP83630-EVK/NOPB の用途: 6 件s: IEEE 1588 PTP Grand-Master Clock Reference Design, Industrial Ethernet Motion-Control Synchronization, Smart-Grid IEC 61850 Substation IED Prototyping, Audio/Video Bridging (AVB) Endpoint Reference, Phasor Measurement Unit (PMU) Lab Validation, PTP Conformance and Test Equipment.
IEEE 1588 PTP Grand-Master Clock Reference Design
The DP83630-EVK/NOPB is the canonical hardware for prototyping an IEEE 1588 v2 grand-master clock, because the on-board DP83630 silicon timestamps packets at the PHY rather than in software, eliminating interrupt latency from the measurement. With a typical 25 MHz reference oscillator and the TI PHYTER Linux PTP stack, engineers can measure sub-microsecond synchronization between two EVKs separated by a managed Ethernet switch. Placed at the PTP master node of an industrial network, the EVK demonstrates the end-to-end transparent clock and ordinary clock behavior that production DP83630 designs must achieve in IEC 61850 and IEEE C37.238 systems.

Industrial Ethernet Motion-Control Synchronization
Synchronized servo drives and motion controllers require distributed clocks within tens of nanoseconds so that multi-axis machines can coordinate motion without jerk. The DP83630-EVK/NOPB provides the hardware timestamping needed to validate an EtherCAT or PROFINET IRT gateway that uses IEEE 1588 as the synchronization backbone. Powered from a 5 V USB rail, the kit can drive a host CPU through MII/RMII at 100 Mbps while exposing raw 1588 event GPIO for oscilloscope measurements of the SFD timestamp alignment. This makes the kit a practical lab tool for verifying drive-to-drive synchronization before committing to a custom PCB.

Smart-Grid IEC 61850 Substation IED Prototyping
IEC 61850 substation Intelligent Electronic Devices (IEDs) require substation-wide clock synchronization typically delivered via IEEE 1588 over Ethernet. The DP83630-EVK/NOPB gives utility-equipment designers a working DP83630 node plus a DP83640 Basic node on the same bench, which is exactly the topology needed to simulate grand-master and slave behavior. With the on-board JTAG header, engineers can trace the 1588 event timestamps directly and verify the 1 microsecond class accuracy required by IEC 61850-9-3. The kit's commercial 0-70C operating range covers indoor substation environments and accelerates conformance testing before designing a production IED card.
おすすめ
Audio/Video Bridging (AVB) Endpoint Reference
AVB endpoints depend on IEEE 802.1AS (which derives from IEEE 1588) to maintain media clock recovery across an Ethernet AVB bridge. The DP83630-EVK/NOPB exposes all DP83630 1588 event GPIOs, allowing AVB stack porters to measure gPTP (generalized PTP) timing and verify the 802.1Qat stream reservation protocol against a deterministic timing source. The kit's 100 Mbps copper port is adequate for AVB class A streams (typical 8-128 kbps per channel after compression) and the bundled DP83640 Basic board helps compare PHY silicon revisions for media-clock robustness.
おすすめ
Phasor Measurement Unit (PMU) Lab Validation
Phasor Measurement Units used in wide-area monitoring systems require synchronized phasor data sampled with sub-100 microsecond accuracy across a power grid. The DP83630-EVK/NOPB provides a real IEEE 1588 hardware timestamping node that lets PMU firmware engineers verify the GPS-disciplined grand-master behavior against a known reference. The kit's 5 V USB power input simplifies portable lab use, and the JTAG header exposes raw 1588 events for compliance testing against IEEE C37.118 sync requirements.
おすすめ
PTP Conformance and Test Equipment
Engineers who build PTP conformance testers or protocol analyzers need a stable, repeatable IEEE 1588 reference to validate their own measurements. The DP83630-EVK/NOPB serves as a known-good grand-master or transparent-clock reference device in the lab because its on-board 25 MHz oscillator and DP83630 silicon timing have been characterized against the TI PHYTER software stack. The kit ships with a DP83640 Basic board, allowing simultaneous reference/measurement comparisons. Two EVKs can be paired to simulate grand-master and slave timing for one-way-delay and offset-from-master measurements in compliance with IEEE 1588-2019.

設計ノート
Power the DP83630-EVK/NOPB from the on-board USB or barrel-jack 5 V input. The board's internal 3.3 V LDO supplies the DP83630 silicon and the 25 MHz oscillator; do not back-feed 3.3 V through the GPIO header or you will conflict with the on-board regulator. For low-jitter PTP measurements, use a clean linear 5 V source rather than a noisy switching brick because supply ripple couples into the reference oscillator and degrades timestamp accuracy.
Use MII or RMII traces that are no longer than 150 mm between the EVK MAC headers and the host CPU, since timing skew on the MII bus adds directly to the 1588 timestamp uncertainty. Keep the 25 MHz oscillator output trace short and away from switching converter inductors. The JTAG header is provided specifically for silicon-level firmware updates; if you design a production board that mirrors the EVK layout, preserve the same crystal footprint and decoupling arrangement to maintain the datasheet timing budget.
Do not assume the DP83620 silicon is a drop-in replacement for the DP83630 in PTP applications: per the TI E2E forum, the DP83620 lacks the IEEE 1588 hardware timestamping block entirely, so any software timestamp workaround will be limited by OS interrupt jitter and will not reach sub-microsecond accuracy. Also note that the EVK ships with both DP83630 and DP83640 Basic boards; do not connect both boards to the same network segment simultaneously without configuring one as transparent clock and the other as ordinary clock, or the PTP packets will loop.
コンプライアンス情報
NOPB suffix indicates lead-free / Pb-free finish compliant with current RoHS rules. AEC-Q100 is not applicable because the EVK is a commercial-grade development board, not a production automotive IC.
