MK2308S-1HILF

Overview

The MK2308S-1HILF is a 3.3V zero delay, low skew buffer manufactured by Renesas Electronics Corporation (formerly IDT). It provides eight low skew outputs operating at frequencies from 10 to 133 MHz. The device utilizes a Phase Locked Loop (PLL) to align the output phase with the input clock, achieving zero input-output delay. Key electrical parameters include an output-to-output skew of less than 200 ps and a device-to-device skew under 700 ps. It features full CMOS outputs with 25 mA drive capability at TTL levels and operates within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Zero input-output delay using proprietary PLL technology
• Eight low skew outputs (<200 ps) with 25 mA drive capability
• Operating frequency range of 10 to 133 MHz
• Industrial temperature operation (-40°C to +85°C)

Applications

• High-speed clock distribution in communication systems
• Board-level testing via tri-state mode
• Systems requiring precise clock synchronization

Procurement Notes

Verify component authenticity through authorized channels as this part may be subject to obsolescence or end-of-life status. Confirm that the specific ordering suffix matches the required package type (SOIC vs TSSOP) and temperature grade, as variations exist within the MK2308 family. Ensure compliance with current RoHS standards given the LF suffix designation.

Selection Notes

Select the MK2308S-1HILF when eight synchronized clock outputs are required with minimal skew. Ensure the design supports the 3.3V supply voltage and accommodates the 16-pin package constraints. Verify that the external feedback connection to the FBIN pin can be implemented to maintain zero delay functionality. Consider thermal management requirements based on the junction-to-ambient resistance values provided in the datasheet.

Part Context

This component belongs to the MK2308 series of zero delay buffers originally developed by Integrated Device Technology (IDT), which was acquired by Renesas Electronics. The 'S' indicates the standard speed grade, '1H' denotes the high-drive version, and 'LF' signifies lead-free packaging. The device is designed for applications demanding low jitter and precise clock alignment.

Replacement Considerations

Direct replacements should be sought within the MK2308 family or compatible zero delay buffers from Renesas. Verify pin compatibility and electrical specifications such as skew and drive strength before substitution.
