Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific factory-assigned frequency code corresponding to the 'Q0136' suffix against the manufacturer's configuration database. Confirm that the 'L' designation matches the required Automotive Grade 2 temperature range of -40°C to +105°C. Ensure the 'K' package type aligns with PCB land pattern requirements. Validate the 'VAO' automotive suffix for standard automotive compliance before finalizing orders.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when low jitter and high stability are critical for automotive signal integrity. Use the ClockWorks Configurator tool to define exact output frequencies and formats. Ensure power supply decoupling with 0.1 μF capacitors on VDD1 and VDD2 pins. Verify that the required output formats (LVDS/LVPECL/HCSL/LVCMOS) match the predefined configuration assigned during manufacturing.
