MK3722GLFTR

Overview

The MK3722GLFTR is a Voltage Controlled Crystal Oscillator (VCXO) manufactured by Renesas Electronics Corporation. It operates at a maximum frequency of 27MHz and utilizes a crystal input with LVCMOS output signals. The device features a single circuit configuration with a 1:2 input-to-output ratio and includes a PLL bypass function. It requires a supply voltage between 3.15V and 3.45V and functions within an operating temperature range of 0°C to 70°C. The component is housed in a 16-TSSOP package with a width of 4.40mm.

Feature Summary

• Voltage Controlled Crystal Oscillator (VCXO) type with 27MHz maximum frequency
• LVCMOS output interface with crystal input
• Supply voltage range of 3.15V to 3.45V
• 16-TSSOP surface mount package

Applications

• Clock generation circuits requiring voltage-controlled frequency adjustment
• Systems utilizing LVCMOS compatible clock inputs
• Industrial or commercial electronics operating within 0°C to 70°C environments

Procurement Notes

The MK3722GLFTR is listed as a discontinued product by the manufacturer. Verification of availability should focus on surplus distributors or secondary market sources, as standard manufacturing channels are no longer active for this specific part number.

Selection Notes

Designers must account for the discontinued status when selecting this component. Ensure that the 16-TSSOP footprint matches the PCB layout and that the 3.15V-3.45V supply voltage aligns with the system power rails. The 27MHz frequency limit and LVCMOS output compatibility are critical constraints for integration.

Part Context

This component belongs to the MK3722 series of clock generators and VCXOs from Renesas. It is distinct from other variants such as the MK3721DLFTR and MK3727DLFTR, which utilize different packages like SOIC-8 and support different frequency ranges. The MK3722GLFTR specifically denotes the 16-TSSOP package variant.

Replacement Considerations

As the part is discontinued, direct substitutes may not be available from the original manufacturer. Engineers should evaluate alternative VCXOs with similar 27MHz specifications, LVCMOS outputs, and 16-TSSOP packaging from other vendors, ensuring pin compatibility and electrical parameter alignment.
