MK5814GTR

Overview

The MK5814GTR is a clock generator integrated circuit manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 3V to 3.63V and supports a maximum frequency of 128MHz. The device features a single circuit configuration with a 1:1 input-to-output ratio. It utilizes an internal Phase-Locked Loop (PLL) for frequency synthesis but does not include differential inputs or outputs. The component accepts clock or crystal inputs and provides LVCMOS output signals. It is housed in an 8-TSSOP package with a width of 4.40mm and is rated for operation between 0°C and 85°C.

Feature Summary

• Integrated PLL-based clock generation supporting up to 128MHz output frequency
• LVCMOS output interface with 1:1 input-to-output signal ratio
• Operates on a 3V to 3.63V power supply within a 0°C to 85°C temperature range
• Available in an 8-TSSOP surface-mount package

Applications

• General-purpose digital system clock distribution
• Embedded controller timing reference
• Consumer electronics board-level clock generation

Procurement Notes

The MK5814GTR is listed as obsolete or not recommended for new designs. Verification of current availability requires checking distributor inventory status directly. The RoHS status is non-compliant, which may restrict usage in regulated markets. Confirm the specific manufacturing date code and any relevant Product Change Notices before procurement.

Selection Notes

Select this component when a fixed-ratio, non-differential LVCMOS clock source is required for systems operating between 3V and 3.63V. Ensure the application does not require spread spectrum capabilities or differential signaling, as these features are absent in this specific part number. Verify that the 8-TSSOP package dimensions fit the target PCB layout constraints.

Part Context

This component belongs to the MK5814 family of clock generators. While other variants like the MK5814SLFTR exist in different packages such as SOIC, the GTR suffix specifically denotes the TSSOP packaging format. The device serves as a basic timing solution compared to more complex synthesizers found in the same manufacturer's portfolio.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Alternative selection should consider components with matching LVCMOS outputs, similar supply voltage ranges, and compatible package footprints.
