VG-4231CA 40.0000M-TGRC3

Oscillators Overview

The VG-4231CA 40.0000M-TGRC3 is a standard crystal oscillator (XO) manufactured by EPSON, operating at a frequency of 40 MHz. It utilizes a CMOS output type and functions with a supply voltage of 3.3V. The device features an enable/disable control function and is housed in a 6-SMD, no lead package with dimensions of 7.00mm x 5.00mm x 1.50mm maximum height. Key electrical specifications include a frequency stability of ±50ppm and an absolute pull range of ±80ppm. The maximum supply current is 10mA, while the disabled current is 7mA. It supports an operating temperature range from -40°C to 85°C.

Oscillators Feature Summary

• CMOS output signal generation for digital logic interfacing
• Enable/disable functionality for power management control
• Surface-mount design for automated assembly integration

Oscillators Applications

• General-purpose timing reference for embedded systems
• Clock source for microcontrollers and processors
• Communication interface synchronization circuits

Oscillators Procurement Notes

This component is officially listed as obsolete or end-of-life by the manufacturer. Verification of availability through authorized distributors is critical, as stock may be limited or discontinued. Ensure that any sourced units match the specific suffix TGRC3 for tape and reel packaging compatibility. Cross-reference part numbers carefully to avoid confusion with similar series variants.

Oscillators Selection Notes

Select this oscillator when a 40 MHz CMOS clock signal is required within a 3.3V system environment. Consider the ±50ppm stability requirement against your system's jitter tolerance. The 6-SMD package size must fit within the designated footprint on the PCB. Verify that the enable/disable pin configuration aligns with your power sequencing strategy.

Oscillators Part Context

This part belongs to the VG-4231CA series of VCXO/XO oscillators from EPSON. The series is known for compact surface-mount packages and stable crystal-based timing. This specific model represents a fixed-frequency variant rather than a voltage-controlled one, despite the series name often implying VCXO capabilities. It serves as a direct replacement for older 40 MHz XO designs in consumer and industrial electronics.

Oscillators Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation due to the obsolete status. Engineers should consult EPSON's official obsolescence notices or contact the manufacturer directly for potential lifecycle alternatives or recommended cross-references.
