CPPLC7L-A7BR-18.432TS

Oscillators Overview

The CPPLC7L-A7BR-18.432TS is a field-programmable blank CMOS output clock oscillator manufactured by Cardinal Components Inc. It operates at a nominal frequency of 18.432 MHz with a ±25 ppm stability rating (indicated by the BR suffix). The device supports a supply voltage range of 3 V to 3.6 V and features tri-state output control for power management. It utilizes a surface-mount plastic package measuring 14.5 mm x 8.8 mm x 4.8 mm with four pins. The component is designed for programming using PG-3000 or PG-3100 instruments.

Oscillators Feature Summary

• Field-programmable blank oscillator architecture allowing custom frequency configuration
• CMOS output signal with tri-state enable/disable functionality
• Surface-mount plastic packaging suitable for automated assembly

Oscillators Applications

• General-purpose digital system clock generation
• Embedded controller timing references
• Communication interface synchronization

Oscillators Procurement Notes

Verify that the specific order matches the requested 18.432 MHz frequency, as this part is a programmable blank oscillator. Confirm the BR suffix corresponds to the required ±25 ppm stability specification. Ensure the procurement documentation specifies the correct programming instrument compatibility, such as the PG-3000 or PG-3100 series, if field programming is intended. Check for RoHS compliance status in the final shipment certificate.

Oscillators Selection Notes

Select this component when a standard fixed-frequency oscillator does not meet specific timing requirements due to its programmable nature. The 3.3 V nominal supply voltage makes it suitable for modern low-voltage logic families. Consider the physical dimensions of the 14.5 mm x 8.8 mm package against available PCB real estate. Verify that the ±25 ppm stability meets the system's jitter and phase noise constraints.

Oscillators Part Context

This part belongs to the CPP series of field-programmable oscillators from Cardinal Components Inc. The series allows users to program the oscillator frequency on-site or during manufacturing, providing flexibility for prototype development and customized production runs. The 'LC' designation indicates a specific package style within the broader product line.

Oscillators Replacement Considerations

Direct replacements are limited due to the proprietary programming requirement. Equivalent parts must support field programming via compatible hardware. Generic 18.432 MHz CMOS oscillators may be used if programmability is not required, but stability and package differences must be evaluated.
