MK5814G

Overview

The MK5814G is a clock generator integrated circuit manufactured by Renesas Electronics Corporation. It operates with a supply voltage range of 3V to 3.63V and supports a maximum frequency of 128MHz. The device features a single circuit configuration with an input-to-output ratio of 1:1. It accepts clock or crystal inputs and provides LVCMOS outputs. The component utilizes Phase Locked Loop (PLL) technology for frequency synthesis but does not include internal dividers or multipliers. 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

• Maximum output frequency of 128MHz
• Supply voltage range of 3V to 3.63V
• LVCMOS output type
• 8-TSSOP surface mount package

Applications

• General clock generation for digital systems

Procurement Notes

The MK5814G is listed as obsolete or discontinued by the manufacturer. Verification of current availability requires checking authorized distributors for remaining stock or end-of-life notices. Compliance status indicates non-RoHS compliance, which may restrict usage in certain regulated markets. Confirm specific ordering suffixes and packaging details with suppliers prior to procurement.

Selection Notes

Select this component when a fixed 1:1 clock generation function at frequencies up to 128MHz is required within a 3V to 3.63V supply domain. Ensure the application environment remains within the 0°C to 85°C operating temperature range. Verify that LVCMOS output levels are compatible with downstream logic inputs. Consider alternative active components if RoHS compliance is mandatory for the target product.

Part Context

The MK5814G belongs to the MK5814 family of clock generators from Renesas Electronics. This series typically includes variants such as the MK5814CMLFT, which shares similar functional characteristics but may differ in package type or environmental rating. The MK5814G specifically denotes the standard commercial grade version in the 8-TSSOP package.
