5L35021B-001NDGI8

Clock Generators, PLLs, Frequency Synthesizers Overview

The 5L35021B-001NDGI8 is a factory-configured VersaClock 3S programmable clock generator from Renesas Electronics. It utilizes a three-PLL architecture to provide up to five unique frequency outputs, supporting PCIe Gen1, Gen2, and Gen3 jitter compliance. The device features configurable output types including LVCMOS and LP-HCSL, with an input frequency range of 1 MHz to 160 MHz. It incorporates Proactive Power Saving (PPS), Performance-Power Balancing (PPB), and Dynamic Frequency Control (DFC) for optimized power-performance balance. An internal OTP memory stores configurations without post-power-up programming.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific suffix 'B-001NDGI8' against official Renesas documentation to confirm factory-set parameters, as generic datasheets describe the base 5L35021 family. Confirm RoHS compliance status and package type (QFN-20) via the manufacturer's current product status page. Ensure the I2C interface requirements match your system design constraints before procurement.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a fixed-frequency solution is preferred over field-programmable alternatives to reduce development time. The factory-configured nature eliminates the need for external configuration circuits or software initialization routines post-power-up. Consider the three-PLL architecture if independent frequency generation from multiple sources is required within a single package.

Clock Generators, PLLs, Frequency Synthesizers Part Context

The 5L35021 belongs to the VersaClock 3S family of programmable clock generators designed by Renesas (formerly IDT). This series targets high-performance timing applications requiring low jitter and flexible output configurations. The device integrates advanced power management features like PPS and PPB, distinguishing it from standard clock generators by offering dynamic power optimization based on performance requirements.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations
