5L35023B-105NLGI Overview
A programmable clock generator is a timing IC that converts a reference input into one or more controlled output frequencies. It belongs to the clock and timing hierarchy, alongside clock generators, PLLs, frequency synthesizers, oscillators, and timing controllers. This category is important in digital systems because processors, serializers, communication links, memory interfaces, and PCI Express equipment require clocks with defined frequency, phase, and enable behavior.
The verified Renesas product page identifies the 5L35023 as a VersaClock programmable clock generator. The verified datasheet search result states that specifications are characterized and guaranteed using a quartz crystal input. It also states that an LVPECL driver change requires selecting the appropriate R3 value. The same datasheet result identifies programmable OE-pin functions, allowing integration of output enable, chip power-down, proactive power saving, two-pin dynamic frequency control, and timer-associated reset functionality.
The B-105NLGI ordering suffix distinguishes this exact Renesas orderable MPN from related 5L35023 variants. Because the supplied records do not expose a complete parameter table or package drawing, pin-level implementation, output frequency range, supply voltage, output format, operating temperature, and package dimensions remain to be confirmed from the manufacturer datasheet before layout or production release. The nearby 5L35023-105NLGI DigiKey result confirms that the broader 5L35023 family is sold as an integrated circuit, but it does not establish equivalence to the B-105NLGI suffix.
Typical use cases include PCI Express clock distribution, low-power consumer electronics, embedded computing, communication equipment, and other systems requiring programmable timing. In a PCI Express design, the clock generator should be selected only after confirming reference frequency, output standard, jitter, supply voltage, configuration method, reset requirements, and package compatibility. In consumer or embedded systems, power-down and output-enable behavior can help control clock activity when the system is idle.
Designers should begin with the crystal and load-capacitance requirements, then verify every datasheet limit and pin function. Decoupling should follow the manufacturer reference circuit, and PCB routing should preserve controlled-impedance clock paths and minimize noise coupling into sensitive analog or RF sections. Before purchasing or substituting the part, request the official Renesas datasheet and confirm the exact B-105NLGI ordering code.

Typical Applications
5L35023B-105NLGI is suitable for 6 applications: PCI Express Clock Distribution, Low-Power Consumer Electronics, Embedded Computing Platforms, Communication Equipment, High-Performance Digital Systems, Test and Measurement Instrumentation.
PCI Express Clock Distribution
The 5L35023B-105NLGI is relevant to PCI Express clock-distribution designs because Renesas identifies the 5L35023 family for high-performance PCI Express applications and describes it as a programmable clock generator. The device can use a quartz crystal reference and provides configurable OE-related functions that may fit systems needing controlled clock enable, power-down, or reset behavior. Before schematic release, verify the exact output frequency, jitter, voltage, output standard, and package against the PCI Express channel requirements. The verified records do not supply those numerical limits, so they must come from the official 5L35023 datasheet.
Recommended
Low-Power Consumer Electronics
The 5L35023B-105NLGI can be considered for low-power consumer electronics when a system benefits from programmable clock generation and configurable clock-control behavior. The Renesas family page explicitly lists low-power consumer applications, while the verified datasheet result identifies OE, power-down, and Proactive Power Saving functions. These functions can help a product control clock activity during idle states, but the actual benefit depends on firmware, configuration, and system power architecture. Confirm supply voltage, current consumption, output formats, and startup behavior before selecting the exact ordering code.
Recommended
Embedded Computing Platforms
The Renesas 5L35023B-105NLGI is a candidate for embedded computing platforms that need a controlled clock reference derived from a quartz crystal. Programmable clock generation can support multiple system domains or timing functions, while the documented OE options can provide power management or control sequencing. The supplied records do not identify the number of outputs, maximum frequency, or programming interface, so an embedded design should verify those points first. Use the manufacturer reference schematic and timing budget rather than assuming compatibility with a generic processor clock requirement.
Recommended
Communication Equipment
The 5L35023B-105NLGI may be useful in communication equipment that requires deterministic clock generation from a quartz reference and flexible output-control behavior. The configurable OE, power-down, Proactive Power Saving, Dynamic Frequency Control, and timer-associated RESET functions described by Renesas provide useful hooks for power management and sequencing. However, RF, serial, or network clock requirements can be highly sensitive to jitter, phase noise, output amplitude, and termination. Those specifications are absent from the verified data and must be checked in the official datasheet before layout release.
Recommended
High-Performance Digital Systems
The 5L35023B-105NLGI is relevant to high-performance digital systems because the 5L35023 family is identified for high-performance PCI Express use and combines a quartz reference with programmable clock generation. The device can help centralize timing distribution and reduce dependence on multiple discrete clock sources when its exact output configuration is suitable. Designers should verify frequency range, output count, supply voltage, jitter, and package before committing to the part. Because those values are not included in the supplied verified records, the official Renesas datasheet is mandatory for engineering sign-off.
Recommended
Test and Measurement Instrumentation
The programmable clock-generator architecture of the 5L35023B-105NLGI can support test and measurement equipment that needs controlled timing references and configurable operating states. The documented OE and reset-related functions may help synchronize subsystems or reduce clock activity during idle periods. Instrument designers still need to evaluate frequency accuracy, phase noise, jitter, output impedance, supply regulation, and calibration requirements. Since the supplied records do not provide these values, verify them in the official datasheet and validate the crystal and reference-circuit implementation on the target board.

Design Notes
Do not treat the B suffix as electrically identical to the related 5L35023-105NLGI code without checking the official ordering table, package drawing, pinout, and electrical characteristics. The supplied records establish family membership but do not provide enough detail to prove drop-in compatibility. Confirm reference frequency, crystal requirements, supply voltage, output standards, programming, and OE/reset behavior before releasing a replacement design.
Use the manufacturer reference layout for crystal, power, ground, and clock-output routing. Keep the crystal path short, maintain the specified grounding and shielding approach, and place input and bypass capacitors according to the official circuit guidance. Because the verified data does not include package dimensions or pin names, do not finalize placement or routing from a generic clock-generator footprint.
Validate output termination and trace geometry against the selected clock standard. The verified datasheet result specifically mentions a 2.5 V LVPECL driver and R3 selection, so the implementation must use the correct resistor value and receiver assumptions. Confirm edge rate, amplitude, return path, impedance, and downstream loading in simulation or measurement before production.
Plan the power rail and decoupling around the exact supply voltage, current consumption, and sequencing requirements in the official datasheet. The available records do not disclose those values, so avoid estimating them. If OE, power-down, or Proactive Power Saving functions are used, verify that downstream clock receivers tolerate the startup and shutdown sequence.
Compliance Information
Compliance information was not present in the supplied verified records. Confirm RoHS, REACH, lead-free, halogen-free, conflict-minerals, and automotive qualification status with Renesas or an authorized distributor using the exact 5L35023B-105NLGI ordering code.
