PI6LC48C21LIEX

Overview

The PI6LC48C21LIEX is a single-output LVCMOS clock synthesizer from the HiFlex family, designed to generate Ethernet reference frequencies. It utilizes a 25MHz crystal input to produce a 125MHz output, or a 26MHz crystal for 130MHz. The device supports full 3.3V (2.375V–3.465V) and 2.5V supply modes. Key electrical parameters include an RMS phase jitter of 0.15ps (1.875MHz–20MHz) and 0.33ps (12kHz–20MHz) at 125MHz. It operates within an industrial temperature range of -40°C to +85°C and is housed in an 8-TSSOP package.

Feature Summary

• Single LVCMOS output optimized for Ethernet reference clocks
• Supports 125MHz output with 25MHz crystal; 130MHz with 26MHz crystal
• Low RMS phase jitter: 0.15ps typical (1.875MHz–20MHz offset)
• Dual voltage support: Full 3.3V or 2.5V supply modes

Applications

• Networking systems
• Ethernet interface circuits

Procurement Notes

Verify the datasheet revision B documentation for accurate electrical characteristics. Confirm the 8-TSSOP package dimensions against JEDEC MO-153F/AA standards. Ensure power supply filtering includes 0.1μF bypass capacitors per pin and a 10Ω resistor with 10μF capacitor on VDDA for optimal jitter performance.

Selection Notes

Select this component when a single-ended LVCMOS Ethernet reference clock is required. It is suitable for designs needing low phase jitter with a 25MHz crystal input. Verify that the system environment falls within the specified -40°C to +85°C industrial operating range.
