Crystal layout considerations for WirelessUSB Lp

Version 1
    Question: What are the crystal layout considerations for a WirelessUSB LP based system?



    The crystal layout is best if the following conditions are met:

    ■ Crystal and radio are on same side of PCB
    ■ Crystal is placed near the crystal pin on the radio
    ■ Crystal trace paths are as short as possible
    ■ Match crystal trace paths for length and parasitic capacitance
    ■ Avoid vias on crystal traces
    ■ Isolate the crystal from noise sources
