PL586-08DC

Clock Buffers, Drivers Overview

The PL586-08DC is a low phase noise, LVPECL Voltage Controlled Crystal Oscillator (VCXO) IC designed for fundamental mode crystals operating between 130 MHz and 200 MHz. It features complementary LVPECL outputs and operates on a 3.3V ±10% supply. Key electrical specifications include a typical pull range of ±140 ppm with 5% linearity, integrated variable capacitors, and very low phase jitter of less than 100 fs RMS. The device achieves -149 dBc/Hz phase noise at 100 kHz offset when operating at 155.52 MHz.

Clock Buffers, Drivers Procurement Notes

Verify the current manufacturer status as the datasheet originates from Micrel Inc., which was acquired by Microchip Technology. Confirm that the PL586-08DC designation remains active and matches the specific die configuration required for your design. Check for any Product Change Notifications (PCN) or obsolescence notices issued after the acquisition to ensure long-term supply availability and parameter consistency.

Clock Buffers, Drivers Selection Notes

Select the PL586-08DC variant specifically if the application requires the Output Enable (OE) pin to default to an enabled state via an internal 60kΩ pull-down resistor. Ensure the external crystal meets the specified loading capacitance (CL = 5.5 pF typical) and ESR requirements (< 30 Ω). Verify that the system power supply maintains 3.3V ±10% to meet the absolute maximum ratings and operational stability.

Clock Buffers, Drivers Part Context

This component belongs to the PL586 series of non-multiplier VCXOs, which also includes the PL586-05DC. The primary distinction between the two variants lies in the internal pull-up/pull-down configuration on the OE pad, determining the default output state upon power-up. Both share identical electrical characteristics regarding frequency, phase noise, and power consumption.

Clock Buffers, Drivers Replacement Considerations

The PL586-05DC is a direct functional alternative within the same family, differing only in the OE pin default logic state. No other cross-model substitutes are documented in the provided source material.
