MK2058-01SILF

Overview

The MK2058-01SILF is a clock jitter attenuator integrated circuit manufactured by Renesas Electronics Corporation. It operates with a maximum frequency of 27MHz and utilizes an internal Phase-Locked Loop (PLL) to reduce timing noise. The device accepts LVCMOS input signals and provides LVCMOS outputs, featuring a 2:1 input-to-output ratio. It is housed in a 20-SOIC package with a width of 7.50mm. The component requires a supply voltage between 3.15V and 3.45V and functions within a temperature range of -40°C to 85°C.

Feature Summary

• Integrated PLL-based clock jitter attenuation for signal integrity improvement
• LVCMOS compatible input and output interfaces
• Single-channel operation with 2:1 input-to-output ratio
• RoHS compliant and lead-free construction

Applications

• Communications equipment requiring low-jitter clock distribution
• Data acquisition systems needing precise timing synchronization
• Industrial control systems utilizing standard CMOS logic levels

Procurement Notes

Verify the specific suffix 'LF' confirms lead-free status and RoHS compliance as per Renesas standards. Confirm the package type matches the 20-SOIC specification with 0.295-inch width. Check current product status, as this part number may be discontinued or subject to last-time buy notices. Ensure the operating voltage range of 3.15V to 3.45V aligns with the target system power rails.

Selection Notes

Select this component when LVCMOS interface compatibility is required alongside jitter reduction capabilities. The 27MHz maximum frequency limits its use to lower-speed clock applications compared to higher-frequency synthesizers. Verify that the single-channel configuration meets the system's clock distribution needs without requiring additional buffering stages.

Part Context

This component belongs to the MK2058 series of clock jitter attenuators. The 'MK2058-01' base model indicates the core functionality, while 'SILF' denotes the specific package variant (SOIC) and lead-free finish. Renesas acquired the IDT portfolio, which originally developed these devices, integrating them into their timing product line.

Replacement Considerations

Check for official Renesas replacement notices or PCNs regarding discontinuation. Alternative solutions may include other Renesas jitter attenuators with similar LVCMOS I/O and frequency ranges, provided pinout and electrical specifications are compatible.
