PI6LC48C51LIE

Overview

The PI6LC48C51LIE is a single LVCMOS output synthesizer from the HiFlex family, designed for Ethernet, SONET/SDH, and SATA reference clock generation. It operates with a full 3.3V or 2.5V supply and supports an output frequency range of 70MHz to 170MHz using a MHz crystal input. The device achieves low phase jitter, typically 0.2ps RMS at 155.52MHz (1.875MHz–20MHz). It features separate analog and core power supplies for noise isolation and is available in a lead-free 8-TSSOP package.

Feature Summary

Single LVCMOS output optimized for Ethernet, SONET/SDH, and SATA interfaces
Supports 70MHz to 170MHz output frequency range via MHz crystal input
Low RMS phase jitter: 0.2ps typical at 155.52MHz (1.875MHz–20MHz)
Full 3.3V or 2.5V supply modes with industrial temperature range (-40°C to +85°C)

Applications

Networking systems
SONET / SDH systems
Server / Storage Systems

Procurement Notes

Verify the ordering suffix 'E' indicates Pb-free and Green compliance, while 'X' denotes tape and reel packaging. Confirm the specific package type matches the required manufacturing process. Ensure the component meets RoHS standards as specified in the datasheet documentation.

Selection Notes

Select this component when a single LVCMOS output is required for frequencies between 70MHz and 170MHz. It is suitable for applications needing low phase jitter and flexible supply voltage options (2.5V or 3.3V). Consider the 8-TSSOP package size for space-constrained designs.

Part Context

The PI6LC48C51LIE belongs to Pericom’s HiFlex family of high-performance clock solutions. It is manufactured by Diodes Incorporated, which acquired Pericom Semiconductor Corporation. The device is part of a broader portfolio of clock generators and support products.

Replacement Considerations

Check for updated revisions within the PI6LC48C51 series. Verify pin compatibility and electrical specifications against alternative single-output LVCMOS synthesizers if sourcing from different manufacturers.

FAQ

What is the typical RMS phase jitter performance?

The typical RMS phase jitter is 0.2ps at 155.52MHz (1.875MHz–20MHz) and 0.25ps at 77.76MHz.

Can the XTAL_IN input accept a single-ended LVCMOS signal?

Yes, the XTAL_IN input can accept a single-ended LVCMOS signal through an AC coupling capacitor, though quartz crystal usage is recommended for guaranteed performance.
