ASSFLP-C16

Overview

The ASSFLP-C16 is a programmable spread spectrum crystal oscillator manufactured by Abracon LLC. It operates within a frequency range of 13 MHz to 160 MHz and supports a supply voltage of 3.3 V. The device features CMOS output levels and ensures ±50 ppm frequency stability. It is housed in a compact 4-SMD, no-lead package with dimensions corresponding to the 5032 footprint. The component supports a maximum supply current of 40 mA and includes a tristate control function on Pin 1. A bypass capacitor of approximately 0.01 uF is recommended between Pin 2 (GND/Case) and Pin 4 (VDD).

Feature Summary

• Programmable frequency generation across a wide spectrum range for flexible system integration.
• Spread spectrum modulation capability designed to reduce electromagnetic interference emissions.
• Integrated tristate control allowing for easy bus isolation and power management.

Applications

• General-purpose clock generation in digital systems requiring low jitter.
• Embedded applications where electromagnetic compatibility is critical.
• Consumer electronics utilizing standard CMOS logic interfaces.

Procurement Notes

Verify the specific frequency configuration required for your application, as this model represents a series or configurable variant rather than a single fixed-frequency part. Confirm that the 3.3 V supply voltage aligns with your system design. Ensure the PCB layout accommodates the 4-SMD no-lead package and includes the recommended 0.01 uF bypass capacitor near the power pin to maintain signal integrity and stability during operation.

Selection Notes

Select this component when a programmable solution is needed to replace fixed-frequency crystals, offering design flexibility. Consider the ±50 ppm stability requirement against your system's timing tolerance. The spread spectrum feature makes it suitable for noise-sensitive environments. Verify that the 40 mA maximum current draw fits within your power budget constraints compared to lower-power MEMS alternatives.

Part Context

The ASSFLP-C16 belongs to Abracon's family of programmable spread spectrum oscillators. These devices are designed to provide precise clock signals while minimizing radiated emissions through frequency dithering. The series typically offers various frequency options and packaging styles to suit different form factors. This specific designation indicates a CMOS output variant compatible with standard digital logic families.

Replacement Considerations

Direct replacements include other Abracon ASSFLP series models with matching frequency and package specifications. Cross-reference with similar spread spectrum oscillators from competitors if availability is an issue, ensuring identical voltage, output type, and stability requirements are met.
