5P35023B-000NLGI Visão geral
A VersaClock 3S programmable clock generator is a timing IC that synthesizes multiple independent reference frequencies from a common reference input, replacing banks of fixed-frequency crystals and oscillators in digital systems. In the broader product taxonomy, programmable clock generators fall under clock generators, which are themselves a subcategory of clock and timing ICs within the power management and signal integrity domain. They serve as the timing backbone of any synchronous digital system, including CPUs, FPGAs, ASICs, SoCs, and high-speed serial interfaces where deterministic, low-jitter reference clocks are mandatory.
Key differentiating features include one-time programmable (OTP) non-volatile memory that stores the customer's frequency configuration, eliminating the need for external resistor programming. The device also supports a configurable output enable (OE) pin function that can operate as OE, PD#, PPS, or DFC control. I2C interface enables in-system programming and dynamic frequency adjustment. Integrated PLLs deliver sub-picosecond RMS phase jitter for PCI Express Gen 3/4 compliance, and the 4x4 mm QFN-24 package with exposed pad offers low thermal resistance suitable for industrial temperature operation.
Typical applications for the 5P35023B-000NLGI span PCI Express Gen 3/4 reference clocks for server and storage controllers, USB 3.0/3.1 reference clocks for hub and peripheral designs, multi-standard SoC clock trees for FPGA and processor reference designs, and consumer audio/video equipment requiring multiple synchronized sample rates. The OE/PD# flexibility supports dynamic power management in mobile platforms, while the LVPECL/LVDS output options enable direct connection to high-speed serializer/deserializer channels without external level translation.
When designing with this device, verify that the OTP image matches your target output frequency plan before committing to volume orders, since OTP configuration cannot be altered once programmed. For PCI Express applications, confirm the part is configured with the correct PCIe-compliant spread-spectrum profile and reference multiplier. The exposed pad must be soldered to a sufficiently large copper pour to maintain thermal performance and meet jitter specifications at the maximum 500 MHz output frequency.

Aplicações típicas
5P35023B-000NLGI é adequado para 6 aplicaçãos: PCI Express Gen 3/4 Reference Clock, USB 3.0/3.1 Hub Clock Distribution, FPGA Multi-Clock Reference Design, Consumer Audio/Video Synchronization, Industrial IoT Gateway Timing, Storage Controller Reference Clocking.
PCI Express Gen 3/4 Reference Clock
The 5P35023B-000NLGI delivers 100 MHz LP-HCSL reference clocks with sub-100 fs RMS phase jitter for PCIe Gen 3/4 compliance. Its three PLL architecture supports six independent PCIe root-complex or endpoint clock domains from a single 25 MHz crystal, replacing discrete clock buffers. The exposed-pad QFN-24 package dissipates under 500 mW at full 500 MHz load, fitting inside the thermal envelope of server add-in cards. Designers configure the OTP image via Renesas' TimingCenter tool to match spread-spectrum profiles required by PCIe CEM specification, eliminating manual SSC calibration in firmware.
Recomendado
USB 3.0/3.1 Hub Clock Distribution
USB 3.0 SuperSpeed hubs require a 100 MHz reference clock distributed to multiple downstream PHY ports. The 5P35023B-000NLGI provides six LVCMOS 100 MHz outputs from one crystal, replacing six standalone oscillators and shrinking PCB area in hub designs. Its I2C dynamic reconfigurability supports USB Type-C alternate-mode clock switching without firmware reprogramming. Power-down via the configurable OE pin (PD# mode) enables per-port clock gating, reducing quiescent current below 5 mA in suspended hubs. The 4x4 mm QFN footprint fits comfortably under Type-C connector shielding.
Recomendado
FPGA Multi-Clock Reference Design
FPGA designs frequently require three to six independent reference clocks for transceiver channels, fabric logic, memory controllers, and PCIe interfaces. The 5P35023B-000NLGI consolidates this clock tree into a single programmable device, generating LVDS 156.25 MHz for transceivers, LVCMOS 100 MHz for PCIe, and LVCMOS 200 MHz for DDR4 from one crystal. OTP programming via TimingCenter lets designers iterate frequency plans during prototyping without re-spinning the PCB. The exposed pad provides low thermal resistance for industrial-temperature operation alongside high-power FPGAs.
Recomendado
Consumer Audio/Video Synchronization
AV receivers and soundbars need synchronized audio sample rates (48 kHz family) and video pixel clocks (148.5 MHz for 4K) generated from a single low-jitter source. The 5P35023B-000NLGI produces both frequency families from its three PLLs, maintaining sub-picosecond jitter for HDMI audio jitter tolerance specs. LVPECL outputs can drive HDMI retimer chips directly. The device's configurable OE pin supports HDMI HPD-triggered clock gating, reducing standby power below HDMI CEC requirements. Small 4x4 mm QFN allows placement near HDMI connectors without disturbing sensitive analog audio paths.
Recomendado
Industrial IoT Gateway Timing
Industrial gateways aggregate multiple fieldbuses (EtherCAT, PROFINET, CAN FD) and require deterministic clock distribution. The 5P35023B-000NLGI generates 50 MHz for microcontroller cores, 25 MHz for PHY interfaces, and 1 Hz for RTC timestamping, all phase-locked to a single TCXO. The OTP image is factory-programmed for the gateway's specific bus mix, eliminating BOM variation across product variants. Its exposed-pad QFN-24 operates reliably across industrial temperature ranges when paired with adequate PCB copper pour. The configurable OE pin supports deterministic power sequencing required by functional-safety standards.
Recomendado
Storage Controller Reference Clocking
NVMe SSDs and SATA controllers need precise 75 MHz, 100 MHz, or 156.25 MHz references depending on PCIe lane configuration. The 5P35023B-000NLGI's six outputs fan out to multiple SSDs in a backplane, eliminating per-drive oscillators and saving cost in JBOD enclosures. LVPECL drive strength meets signal integrity requirements for backplane trace lengths up to 12 inches. OTP programming lets the same SKU serve 6G SATA and PCIe Gen 3 applications with different image options. Low power dissipation under 400 mW enables fanless storage chassis designs.

Notas de projeto
Solder the exposed thermal pad (pin 25) of the 24-VFQFN to a continuous ground pour spanning at least 16 mm² of copper area on the top layer. The exposed pad provides both the primary heat dissipation path and the low-inductance ground reference for the internal PLLs. Insufficient pad soldering will degrade phase jitter and may cause PLL lock failure at 500 MHz output frequencies. Use 0.5 mm pitch land patterns with NSMD pads.
Verify the OTP image contents before committing to volume orders. The 5P35023B is one-time programmable; once programmed at the factory, the frequency plan cannot be modified. For development, request an unprogrammed 'blank' part or use Renesas' TimingCenter tool to generate the OTP image and share it with your Renesas field application engineer before placing the production order. Mis-ordered OTP images are non-refundable.
Provide three separate supply rails: VDD_CORE (1.8V typical), VDD_PLL (2.5V typical), and VDD_IO (3.3V typical). Each rail should be decoupled with a 100 nF ceramic capacitor placed within 2 mm of the corresponding supply pin, plus a 10 µF bulk capacitor shared across the device. Mixing supplies from noisy switching converter rails can inject spurs into the PLL VCO, manifesting as deterministic jitter on the output clocks.
