Application Hints on the Crystal Oscillator
1. Application Hints on the crystal oscillator
The crystal oscillator achieves a turn on time less than 1 msec when the
specified crystal is used. To achieve this, a NIC oscillator type is implemented
in the TDK 5100 F. The input impedance of this oscillator is a negative resis-
tance in series to an inductance. Therefore the load capacitance of the crystal
CL (specified by the crystal supplier) is transformed to the capacitance Cv.
CL:
crystal load capacitance for nominal frequency
ω
:
angular frequency
L:
inductance of the crystal oscillator
Example for the ASK-Mode:
Referring to the application circuit, in ASK-Mode the capacitance C7 is replaced
by a short to ground. Assume a crystal frequency of 13.56 MHz and a crystal
load capacitance of CL = 20 pF. The inductance L at 13.5 MHz is about 4.6
μ
H.
Therefore C6 is calculated to 12 pF.
