Optional Main Clock Module
The main clock and subclock for the MCU are mounted on the micro-board as a standard. The clock
module on the M-Station is an optional feature for use when you require frequencies other than ones
supplied by the micro-boards.
3.7.1
Mounting Crystal Oscillator
A crystal oscillator can be mounted on J7 with component positions and connections as shown in the
diagram above. Please consult the specification for the crystal oscillator before selecting biasing
resistors and capacitors. It may be convenient to use a 14-pin socket and adapter module to install
crystal oscillators with biasing resistors and capacitors. In those cases, DigiKey part no. A401-ND
(from Aries Electronics, Inc.) is the recommended 14-pin socket and DigiKey part no. A102-ND (also
from Aries) is the recommended DIP header.
3.7.2
Mounting Full-Size Oscillator
J7 is designed to accept full-size oscillators in pins 1, 7, 8 and 14. A full-size oscillator may be
purchased from DigiKey.
