2P4M(35)-AZ

Scrs Overview

The 2P4M(35)-AZ is a programmable clock generator manufactured by Renesas Electronics Corporation. It belongs to the VersaClock family of field-programmable synthesizers designed for generating precise clock signals in electronic systems. The device utilizes Phase-Locked Loop (PLL) technology to derive output frequencies from a standard input crystal or clock source, allowing for flexible frequency synthesis without requiring multiple discrete oscillators. This component supports configurable spread spectrum modulation to reduce electromagnetic interference within the host system. It features an internal One-Time Programmable (OTP) ROM that enables field programmability through dedicated configuration registers, simplifying board design and reducing component count.

Scrs Feature Summary

• Field programmability via OTP ROM and addressable configuration registers
• Configurable spread spectrum modulation for EMI reduction
• Phase-Locked Loop (PLL) based frequency synthesis
• Power-down feature with tri-stated outputs

Scrs Applications

• General purpose clock generation for embedded systems
• Replacing multiple fixed-frequency crystals and oscillators
• Systems requiring low electromagnetic interference (EMI)

Scrs Procurement Notes

Verify the specific ordering suffix and package variant when sourcing, as availability may vary between active and obsolete statuses. Confirm the presence of the required programming tool or software utility for configuring the OTP memory before production deployment. Ensure the input crystal specifications match the device's operational requirements for stable PLL locking.

Scrs Selection Notes

Select this component when a single-output programmable clock solution is needed to replace multiple fixed oscillators. Consider the operating voltage and package constraints against the target application environment. Verify that the required output frequency range falls within the device's capabilities and that the I2C interface compatibility matches the system controller.

Scrs Part Context

This part is part of the VersaClock series, which focuses on low-cost, field-programmable clock synthesizers. These devices are engineered to simplify system design by consolidating clock generation functions into a single IC, thereby saving board space and reducing overall bill of materials costs compared to using discrete crystal and oscillator components.

Scrs Replacement Considerations

Check for updated versions within the VersaClock family that may offer improved power consumption or additional output channels. Verify pin-to-pin compatibility if substituting with other SOIC-8 clock generators, ensuring electrical parameters such as drive strength and supply voltage remain within acceptable limits.
