MK2304S-1LFT

Overview

The MK2304S-1LFT is a low jitter, low skew, high-performance Phase Lock Loop (PLL) based zero delay buffer manufactured by Renesas Electronics Corporation. It provides four low skew outputs at speeds up to 133 MHz at 3.3 V. The device includes two banks of two outputs each with a 1X multiplier. In zero delay mode, the rising edge of the input clock aligns with the rising edges of all four outputs. It features output-to-output skew less than 200 ps and operates within a supply voltage range of 3.0 V to 3.6 V.

Feature Summary

• Zero input-output delay with PLL-based synchronization
• Four low skew outputs organized in two banks of two 1X outputs
• Output-to-output skew less than 200 ps
• Supports output frequencies up to 133 MHz at 3.3 V

Applications

• High-speed clock distribution systems
• Systems requiring precise clock alignment and low jitter
• Applications utilizing Spread Spectrum clock generators

Procurement Notes

Verify component authenticity through authorized channels as the product originates from IDT, now part of Renesas. Confirm package type is 8-pin SOIC and temperature range matches commercial specifications (0 to +70 °C). Ensure RoHS compliance via the LF suffix. Check for obsolescence status before procurement planning.

Selection Notes

Select this component when zero delay buffering with minimal skew is required for up to four outputs. Ensure the application supports 3.3 V operation and requires frequencies up to 133 MHz. Verify that the 8 mA drive capability at TTL levels meets load requirements. Consider thermal resistance characteristics if operating in still air environments.

Part Context

This component belongs to the MK2304 series of zero delay buffers originally developed by Integrated Device Technology (IDT). Following Renesas Electronics' acquisition of IDT's timing products, these components are managed under the Renesas portfolio. The MK2304S-1LFT specifically denotes the lead-free, commercial temperature variant packaged in tubes.

Replacement Considerations

Consult official Renesas or SiTime documentation for verified substitutes. Cross-reference pinouts and electrical parameters such as skew and jitter specifications. Ensure compatibility with existing PCB layouts and power supply constraints.
