PI6LC48L0201LIE

Overview

The PI6LC48L0201LIE is a 2-output LVDS synthesizer from the HiFlex family, optimized for generating Ethernet reference clock frequencies. It utilizes proprietary low phase noise PLL technology to achieve ultra-low phase jitter. The device supports selectable crystal oscillator interfaces or LVCMOS/LVTTL single-ended clock inputs. Using a 25MHz crystal, it generates output frequencies of 62.5MHz, 125MHz, and 156.25MHz based on frequency select pin settings. It operates with full 3.3V or 2.5V supply modes and is available in a lead-free 20-TSSOP package.

Feature Summary

• Two differential LVDS output pairs
• Selectable crystal oscillator interface or LVCMOS/LVTTL single-ended clock input
• Supports output frequencies: 62.5MHz, 125MHz, 156.25MHz
• RMS phase jitter @ 156.25MHz (1.875MHz – 20MHz): 0.2ps (typical)
• Full 3.3V or 2.5V supply modes
• Industrial ambient operating temperature (-40°C to +85°C)

Applications

• Networking systems

Procurement Notes

Verify the ordering suffix 'I' indicates industrial temperature range operation and 'E' denotes Pb-free and Green compliance. Confirm packaging type; adding an 'X' at the end of the ordering code denotes tape and reel packaging. Ensure the component matches the specific 20-pin TSSOP package description for the intended application.

Selection Notes

Select this component for applications requiring low phase jitter Ethernet reference clocks. Use N_SEL pins to configure output frequencies from a 25MHz crystal source. Ensure power supply filtering techniques are applied, including separate VDD, VDDA, and VDDO connections with appropriate bypass capacitors, to maintain optimal jitter performance.
