PI6LC48H02LIEX

Overview

The PI6LC48H02LIEX is a clock generator compliant with PCI Express 4.0/3.0/2.0/1.0 and Ethernet standards, designed for PC or embedded systems. It accepts a 25MHz crystal input and generates two pairs of differential HCSL outputs at selectable frequencies: 25MHz, 100MHz, 125MHz, or 200MHz. The device operates on a 3.3V ±10% supply voltage within an industrial temperature range (-40°C to +85°C). Key electrical specifications include a typical cycle-to-cycle jitter of 35ps and RMS phase jitter of 0.32ps at 100MHz (12kHz–20MHz bandwidth). It utilizes Diodes' patented PLL technology and is housed in a 16-pin TSSOP package.

Feature Summary

• PCIe 4.0/3.0/2.0/1.0 compliant with LVDS compatible outputs
• Generates 25MHz, 100MHz, 125MHz, or 200MHz via S1/S0 pin selection
• Low jitter performance: 35ps cycle-to-cycle (typ), 0.32ps RMS phase jitter @ 100MHz
• Industrial temperature range (-40°C to +85°C) with 3.3V ±10% supply

Applications

• PCI Express compliant systems
• PC motherboards
• Embedded networking systems

Procurement Notes

Verify the ordering suffix 'E' confirms Pb-free and Green packaging status, and 'X' indicates Tape/Reel delivery format. Confirm the L16 package code corresponds to the 16-pin Wide TSSOP footprint. Ensure the component meets RoHS 3 and REACH requirements as specified in the manufacturer's quality definitions before procurement.

Selection Notes

Select this component when PCIe Gen 1 through Gen 4 clock generation is required with low jitter constraints. The output frequency must be configured using the internal pull-up resistors on S0 and S1 pins. External termination resistors (RS=33Ω, RT=49.9Ω) are mandatory for proper HCSL signal integrity. Verify that the application environment stays within the -40°C to +85°C operating temperature range.

Part Context

This part belongs to the HiFlex family of clock generators from Diodes Incorporated (formerly Pericom Semiconductor). It is specifically engineered for high-speed serial interface timing applications. The LIEX designation identifies the specific industrial grade, lead-free, tape-and-reel variant of the base PI6LC48H02 silicon die.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-reference with other PI6LC48 series variants only if pin compatibility and electrical parameters match exactly.
