SG-8002CA-PTM

Overview

The SG-8002CA-PTM is a programmable crystal oscillator (XO) manufactured by EPSON, designed for standard timing applications. It operates with a 5V supply voltage and features TTL output logic. The device supports a frequency range from 1 MHz to 55 MHz, with a frequency stability of ±100 ppm. It includes an enable/disable function and is housed in a compact 4-SMD, no-lead package measuring 7.00mm x 5.00mm. The maximum supply current is 45mA during operation and 30mA when disabled. The component is rated for an operating temperature range of -40°C to 85°C.

Feature Summary

• Programmable frequency generation within the 1 MHz to 55 MHz range
• TTL output logic compatible with standard digital circuits
• Integrated enable and disable control functionality
• Compact surface-mount package design for space-constrained layouts

Applications

• General-purpose clock signal generation in electronic systems

Procurement Notes

This component has been officially discontinued by the manufacturer as indicated by the Product Change Notification dated October 10, 2025. Procurement should focus on verifying the authenticity of remaining stock from authorized distributors. Buyers must confirm that the specific part number matches their design requirements before acquisition, as end-of-life status may limit future supply availability. Cross-reference with alternative models from the same series if necessary.

Selection Notes

Engineers selecting this oscillator should consider its TTL output compatibility and 5V supply requirement. The ±100 ppm stability suits general applications but may not meet high-precision needs. The enable/disable feature allows for power management strategies. Designers must account for the discontinuation status and plan for long-term supply chain risks or substitute components from the SG-8002CA series.

Part Context

The SG-8002CA-PTM belongs to the SG-8002CA series of programmable crystal oscillators from EPSON Timing. This series is known for offering customizable frequencies within specified ranges while maintaining standard form factors. The PTM suffix typically denotes specific packaging or programming parameters defined by the manufacturer. These oscillators are widely used in consumer electronics and industrial devices where flexible clocking solutions are required.

Replacement Considerations

Due to the official discontinuation notice, direct replacement parts should be sourced from the SG-8002CA family. Verify pinout compatibility and electrical specifications such as voltage and output type. Consult the manufacturer's part number guide for equivalent models with similar frequency ranges and package dimensions.
