PL500-17TI-R

Clock Generators, PLLs, Frequency Synthesizers Overview

The PL500-17TI-R is a low phase noise Voltage Controlled Crystal Oscillator (VCXO) operating in the 17MHz to 36MHz range. It features LVCMOS output with tri-state control and accepts fundamental crystal inputs within the specified frequency band. The device integrates high linearity variable capacitors, offering a ±150 ppm pull range with typical 5% linearity. Key electrical parameters include a maximum supply voltage of 3.63V, RMS period jitter of 2.5ps, and phase noise of -142 dBc/Hz at 10kHz offset from 27MHz. It operates on 2.5V to 3.3V supplies and is housed in a 6-pin SOT23 package.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the suffix 'I' confirms the industrial temperature range (-40°C to +85°C). Confirm the 'R' suffix indicates Tape & Reel shipping. Ensure the source document identifies Micrel as the manufacturer, noting subsequent corporate acquisitions may affect branding but not the component specifications.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this part when an industrial temperature grade is required for VCXO applications between 17MHz and 36MHz. The SOT23-6L package is suitable for space-constrained designs. Ensure the external crystal meets the specified load capacitance (approx. 8.9pF at 2.5V) and drive level limits (max 200µW) to maintain oscillation stability.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the PL500-17 family of VCXOs. The specific suffix 'I' denotes the Industrial temperature variant (-40°C to +85°C), distinguishing it from the Commercial grade ('C'). The 'T' indicates the SOT23-6L package, and 'R' specifies Tape & Reel packaging. The device was originally manufactured by Micrel Inc.
