5X1503S-000NLGI8

Clock Generators, PLLs, Frequency Synthesizers Overview

The 5X1503S-000NLGI8 is a MicroClock programmable clock generator from Renesas Electronics, designed for low-power consumer and wearable applications. It features a 1 PLL + DCO architecture with an embedded crystal, eliminating the need for external input sources. The device supports one LVCMOS input and three LVCMOS outputs, with a maximum frequency of 100MHz. Key specifications include a supply voltage range of 1.71V to 1.89V and an operating temperature range of -40°C to 85°C. The 'S' suffix indicates spread spectrum capability for EMI reduction. It is housed in a 10-VFQFPN (2x2 mm) package.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific ordering suffix matches the required spread spectrum feature. Check for recent product change notices regarding packaging or assembly location updates. Ensure compatibility with the Timing Commander software tool for configuration if reprogramming is needed.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this model when an embedded crystal solution is preferred to save board space. Choose the 'S' variant specifically for applications requiring spread spectrum modulation to meet EMI standards. Verify that the single LVCMOS input and three LVCMOS output constraints fit the system timing requirements. Consider the 1.8V core voltage constraint for power budget calculations.
