MK3720DLF

Overview

The MK3720DLF is a Voltage Controlled Crystal Oscillator (VCXO) manufactured by Renesas Electronics. It operates at a maximum frequency of 54MHz and utilizes a crystal input with CMOS output format. The device supports a 2:3 input-to-output ratio and functions within a supply voltage range of 3.15V to 3.45V. Designed for surface mount installation, it is housed in an 8-SOIC package measuring 0.154 inches (3.90mm) in width. The component is rated for an operating temperature range of 0°C to 70°C.

Procurement Notes

The MK3720DLF is classified as obsolete or end-of-life by the manufacturer. Verification of current availability requires checking authorized distributors for remaining stock or last-time buy status. Sourcing should prioritize verified suppliers to ensure component authenticity given the discontinued status.

Selection Notes

Select this component for designs requiring a fixed-frequency VCXO near 54MHz with CMOS outputs. Ensure the application environment stays within the 0°C to 70°C operating temperature range. Verify that the PCB layout accommodates the 8-SOIC package dimensions and that the power supply provides stable voltage between 3.15V and 3.45V.

Part Context

This part belongs to the MK3720 series of clock generators and oscillators from Renesas. It is functionally related to variants such as the MK3720DTR and MK3720DLFTR, which share similar electrical specifications but differ in packaging formats like tape-and-reel versus tube.

Replacement Considerations

Due to the obsolete status, direct replacements may be limited. Evaluate the MK3720DTR or MK3720DLFTR if available, noting potential differences in packaging. Cross-reference with other Renesas VCXO families for functional compatibility.
