Dual Channel High Precision 26 Bit Frequency Counter Using CPLD XC95108XL for QCM Sensor System
Keywords:
QCM sensor, frequency counter, CPLD.Abstract
Frequency counter is main part of the
instrumentation system for QCM sensor. Precision and stability
of the frequency counter together with the compactness of the
frequency counter are crucial factors in development of
frequency counter for QCM sensor. CPLD is one of the good
choice to be used as a core device to develop frequency counter.
The design of the CPLD to be used as a frequency counter can
be easily implemented as the availability of CPLD big amount
of macrocells is existed. However, careful system design is also
needed to optimize the used of the CPLD resources. In the
development of CPLD as frequency counter, data transfer from
CPLD to microcontroller plays a significant role to the resource
usage. In the use of Xilinx XC95108 as 26 bit dual frequency
counter, data transfer with 4 bit data width is the most
appropriate one to be implemented. The developed frequency
counter shows a high accuracy, precision and stability. The
developed frequency counter has a 1 Hz precision and stability.
