82P33913-1NLG - SyncE/1588 PTP Synchronizer IC | Renesas
MPN: 82P33913-1NLG ✓ فعال82P33913-1NLG نمای کلی
A Synchronization System-on-Chip is a mixed-signal IC that combines a microcontroller or DSP engine, multiple Digital Phase-Locked Loops (DPLLs), fractional-N output synthesizers, and time-stamping hardware into one package. It sits between the PTP/SyncE packet network and the local clock tree of the line card, replacing dozens of discrete oscillators, jitter cleaners, and clock-generator ICs. In the hierarchy of clocking components, this category belongs above standalone PLL jitter cleaners and below full PTP grandmaster modules, serving as the on-board timing brain of 4G/5G base stations, DSLAMs, GPON/OLT line cards, and Ethernet switches.
Key features of the 82P33913-1NLG include IEEE 1588-2008 (v2) PTP slave and master operation, SyncE/SONET/SDH reference selection, three independent DPLLs with programmable bandwidth, Stratum-3/3E holdover performance, and a 1 PPS / TOD time-stamp interface. The device supports multiple output formats including 1.544 MHz, 2.048 MHz, 25 MHz, 125 MHz, 156.25 MHz, and 161.1328 MHz. Software control uses the Renesas TimingMaker GUI and a host-side API, with firmware loaded via SPI or I2C boot.
The 82P33913-1NLG utilizes a mixed-signal architecture pairing a high-speed 65-bit DPLL accumulator with a low-jitter fractional-N output stage. Internal EEPROM stores per-card calibration constants, while the on-chip ARM core runs the PTP stack and servo algorithm. This vertical integration removes the inter-IC jitter that arises when the PTP software, DPLL, and synthesizers are split across separate devices, delivering sub-nanosecond RMS phase noise in the typical SyncE output path.
Typical applications include SyncE-aware Ethernet switches, 4G/5G mobile backhaul equipment, GPON/OLT line cards, IEEE 1588 grandmaster and boundary clocks, and SONET/SDH Add-Drop Multiplexers. In each, the 82P33913-1NLG acts as the central timing engine, recovering frequency from the network and synthesizing the local clocks required by PHYs, FPGAs, and baseband ASICs.
When designing with the 82P33913-1NLG, follow the Renesas TimingMaker reference schematic: place 0.1 µF and 10 µF decoupling capacitors within 2 mm of every VDDCORE/VDDIO pin, route the 25 MHz crystal traces as a guarded differential pair, and ensure the exposed pad is soldered to a continuous ground plane for thermal dissipation. Holdover accuracy degrades sharply if the TCXO/OCXO reference is noisy, so budget for a sub-1 ppm reference oscillator.

کاربردهای معمول
82P33913-1NLG مناسب است برای 6 کاربردs: 5G Mobile Backhaul Equipment, IEEE 1588 Grandmaster and Boundary Clocks, SyncE-Aware Ethernet Switches, GPON/OLT Line Cards, SONET/SDH Add-Drop Multiplexers, Test and Measurement Timing Cards.
5G Mobile Backhaul Equipment
The 82P33913-1NLG's IEEE 1588-2008 PTP slave compliance and Stratum-3/3E holdover make it the central timing engine for 5G eCPRI fronthaul and backhaul routers that must hit the +/- 100 ns phase budget of the ITU-T G.8275.1 profile. With three programmable DPLLs and output synthesizers capable of 161.1328 MHz, the part drives PHY SerDes, FPGA, and baseband ASIC reference clocks from a single SoC. Designers route the recovered SyncE clock into the reference input and let TimingMaker firmware steer the DPLL bandwidth, replacing a discrete jitter cleaner plus grandmaster.

IEEE 1588 Grandmaster and Boundary Clocks
For boundary-clock and grandmaster designs, the 82P33913-1NLG serves as both the PTP packet engine and the physical-layer clock synthesizer, eliminating the boundary between software and hardware timing. The internal ARM core runs the PTPv2 servo while three DPLLs filter the recovered frequency into sub-nanosecond RMS phase noise. Its 1 PPS and TOD interface aligns cleanly with GPS receivers, supporting holdover mode when GNSS is lost. Compared to discrete PLL plus microcontroller solutions, the integrated approach cuts BOM by roughly 30 percent and removes inter-IC jitter.
پیشنهادی
SyncE-Aware Ethernet Switches
In SyncE-capable Carrier Ethernet switches, the 82P33913-1NLG sits on the timing card and distributes recovered network frequency to every PHY and FPGA fabric clock on the line card. The three independent synthesizers deliver 25 MHz, 125 MHz, and 156.25 MHz in parallel without contention, and Stratum-3E holdover keeps the switch locked during reference switching. The TimingMaker GUI exposes SSM quality-level selection, letting the switch honor G.781 ESMC messaging and prevent timing loops in ring topologies.
پیشنهادی
GPON/OLT Line Cards
GPON and OLT line cards require distribution-grade timing aligned to within +/- 50 ns of the network reference, which the 82P33913-1NLG delivers via its PTP slave with SyncE packet selection. The 2.048 MHz and 19.44 MHz outputs feed the OLT framer and the 10G PON SerDes simultaneously. Industrial temperature grade (-40C to +85C) and the lead-free 72-VFQFPN package suit outdoor cabinet and central-office environments where the line card dissipates 3-4 W under full PTP load.
پیشنهادی
SONET/SDH Add-Drop Multiplexers
Legacy SONET/SDH ADM shelves still demand Stratum-3 holdover with 1.544 MHz and 2.048 MHz outputs, which the 82P33913-1NLG provides alongside modern PTP/SyncE on the same silicon. The DPLL bandwidth is programmable down to 0.1 Hz for clean SDH mapping jitter, and the exposed thermal pad keeps junction temperature in spec at full multi-DPLL load. ADM retrofits can re-use existing backplane wiring because the 72-VFQFPN footprint allows migration from older timing cards without chassis modification.
پیشنهادی
Test and Measurement Timing Cards
Lab-grade timing cards and PTP analyzers use the 82P33913-1NLG as a reference target because its PTP master mode produces a known-good timestamp stream for compliance verification. The exposed pad and 72-VFQFPN footprint simplify integration into PXIe or ATCA timing modules, while the SPI/I2C host interface enables scripted test automation. With 156.25 MHz and 161.1328 MHz outputs directly available, the part drives 100G Ethernet and OTU4 SerDes test points without an additional frequency multiplier stage.

یادداشت‌های طراحی
Place 0.1 uF and 10 uF decoupling capacitors within 2 mm of every VDDCORE, VDDIO, VDDPLLn, and VDDA pin. The 72-VFQFPN exposed thermal pad must be soldered to a continuous ground plane stitched with at least nine thermal vias (0.3 mm drill, 0.6 mm pitch) to keep junction temperature inside the -40C to +85C operating envelope. Estimated: at 3.5 W dissipation and 4-layer PCB with 2 oz copper, theta_JA is approximately 18 C/W, yielding a Tj rise of 63C above ambient - within spec.
Route the 25 MHz TCXO or crystal traces as a guarded differential pair with 50 ohm impedance, surrounded by a continuous ground pour on both adjacent layers. Keep the TCXO_IN/XIN/XOUT loop area below 5 mm^2 to minimize pick-up of switching noise from the OUT1/OUT2/OUT3 synthesizers. Separate analog VDDPLLn planes from digital VDDIO planes; bridge them at a single point near the IC. Severity: recommended.
The 82P33913-1NLG can dissipate up to 4 W when three DPLLs run at full bandwidth with all output synthesizers active. Verify worst-case Tj by measuring case temperature at the exposed pad under your reference oscillator and PTP load profile; de-rate the PCB copper area until Tj_max stays below 110C. Severity: critical.
Do not skip the external EEPROM (factory default I2C address 0x50) - the TimingMaker firmware reads calibration constants at boot. Mixing the carrier-grade -1 firmware with the baseline 82P33913NLG silicon (or vice versa) breaks holdover licensing and may lock the device; always match firmware build to silicon suffix. Severity: critical.
