MK1574-01BSILFTR

Overview

The MK1574-01BSILFTR is a clock/frequency synthesizer IC manufactured by Renesas Electronics Corporation. It utilizes a Phase-Locked Loop (PLL) architecture to accept an 8 kHz clock input as a reference signal. The device generates multiple popular communications frame rates from this low-frequency reference. It features CMOS outputs and operates within a temperature range of -40°C to 85°C. The component is housed in a 16-SOIC package with a width of 3.90 mm.

Feature Summary

• Generates standard communications frame rates using an 8 kHz reference input
• Utilizes Phase-Locked Loop technology for frequency synthesis
• Provides CMOS output signals

Applications

• Frame rate communication systems
• Clock distribution networks requiring specific frame rate generation
• Communications equipment utilizing PLL-based timing solutions

Procurement Notes

Verify the complete part number including suffixes such as LFTR against official Renesas documentation to ensure correct packaging and material specifications. Confirm that the 16-SOIC package dimensions match the design footprint requirements. Check the operating temperature range specifications against environmental constraints before procurement.

Selection Notes

Select this component when a stable frequency source is required derived from a precise 8 kHz reference. Ensure the system design accommodates CMOS output voltage levels. Verify that the single circuit configuration meets the timing requirements without needing additional external dividers or multipliers beyond the internal PLL capabilities.

Part Context

This part belongs to the MK1574 series of clock synthesizers designed for telecommunications applications. It serves as a timing solution for generating standardized frame rates essential in digital communication protocols. The series provides reliable frequency multiplication from low-frequency references to higher-speed data rates.

Replacement Considerations

Consult official cross-reference lists for compatible alternatives. Verify pin compatibility and electrical parameters if substituting with other PLL synthesizers. Ensure any replacement maintains the 8 kHz input requirement and CMOS output characteristics.
