5L1503L-000NVGI

Clock Generators, PLLs, Frequency Synthesizers Overview

The Renesas 5L1503L-000NVGI is a MicroClock programmable clock generator featuring an embedded crystal and ultra-low power architecture. It utilizes a 1 PLL + DCO design with one embedded crystal, supporting up to three unique frequency outputs via OTP programming. The device operates on a 1.71V to 1.89V supply voltage, delivering LVCMOS outputs with a maximum frequency of 100MHz. Key features include Proactive Power Saving (PPS), Dynamic Frequency Control (DFC), and a dedicated low-power 32.768kHz output for RTC applications. It is housed in a 10-VFQFPN package.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Embedded Crystal: Integrated crystal eliminates the need for external input sources.
• Ultra-Low Power: Supports system date/time keeping at 32.768kHz with less than 1.5μA current consumption.
• Dynamic Frequency Control: Allows switching between configurations dynamically to reduce frequency overshoot/undershoot.
• Programmable Amplitude: Outputs support configurable amplitudes (1.0V, 1.1V, 1.2V, 1.8V) for low swing requirements.

Clock Generators, PLLs, Frequency Synthesizers Applications

• Battery-powered consumer electronics
• Wearable devices
• Smart devices requiring low-power timing

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify component status as the 5L1503 series has been designated as obsolete by Renesas Electronics. Production discontinuation notices indicate end-of-life status. Ensure compatibility with existing designs before procurement, as availability may be limited to remaining stock or last-time buys from authorized distributors.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select the 5L1503L variant specifically for its embedded crystal feature, which removes the requirement for an external oscillator. This model supports I²C reprogramming and stores up to four independent configurations in internal OTP memory. Verify that the required output frequencies fall within the 0.032768MHz to 100MHz range and that the LVCMOS output type matches the load requirements.

Clock Generators, PLLs, Frequency Synthesizers Part Context

The 5L1503L belongs to the MicroClock family of miniature, programmable clock generators designed for space-constrained applications. The 'L' suffix denotes the version with an embedded crystal. The device is part of a series that includes spread spectrum variants (5X1503S) and standard versions, all sharing the same core 1 PLL + DCO architecture and 10-VFQFPN packaging.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. The 5L1503 series is marked as obsolete. Designers should consult Renesas or SiTime for potential next-generation replacements suitable for new designs, as transition plans were expected to complete by late 2026.
