PL586-15DC

Clock Buffers, Drivers Overview

The PL586-15DC is a low phase noise Voltage Controlled Crystal Oscillator (VCXO) IC designed for fundamental mode crystals operating between 75MHz and 125MHz. It features complementary LVPECL outputs, a typical pull range of ±125ppm with less than 5% linearity, and integrated variable capacitors. The device operates on a 3.3V supply and achieves very low phase jitter of 120fs RMS at 125MHz. The -15 suffix indicates an internal 60kΩ pull-up resistor on the Output Enable pin, defaulting to enabled state.

Clock Buffers, Drivers Feature Summary

• Low Phase Noise: < -150dBc/Hz at 100kHz offset
• High Pull Range: ±125ppm typical with <5% linearity
• Integrated Variable Capacitors for crystal tuning
• Complementary LVPECL Outputs with 300ps rise/fall times

Clock Buffers, Drivers Applications

• SONET Clocking
• WiMax Systems
• CPRI Interfaces
• OBSAI Architectures
• Fiber Channel Applications

Clock Buffers, Drivers Procurement Notes

Verify the specific ordering suffix 'D' confirms Die packaging in waffle pack format. Confirm the '-15' designation matches designs requiring an internal pull-up resistor on the OE pin. Ensure compatibility with commercial temperature grade (0°C to 70°C). Check for preliminary status updates or final datasheet revisions before production integration.

Clock Buffers, Drivers Selection Notes

Select PL586-15DC over PL586-18DC when the design requires the Output Enable pin to be active by default via an internal pull-up resistor. Ensure the application utilizes fundamental mode crystals within the 75MHz to 125MHz range. Verify that the system can accommodate the 50mA supply current and LVPECL output voltage levels relative to VDD.

Clock Buffers, Drivers Part Context

This component belongs to the PL586 family of non-multiplier VCXOs manufactured originally by Micrel Inc., now part of Microchip Technology. The PL586-15 variant specifically configures the Output Enable logic with a pull-up resistor, distinguishing it from the PL586-18 which uses a pull-down resistor. It serves as a high-performance clock source for demanding telecommunications standards.
