The crystal oscillator's metal case may be visible in the area (on top) indicated in broken lines
, but this has no effect on the
device's characteristics.

Pattern (GND, power line,
signal line,soldering pattern

is not allowed.
3 )
GND pattern recommended area
#14
In this area,(
) is connected to internal circuit.
In this area, do not pattern layout surely.
It becomes the cause of trouble.
1)
The cylinder of the crystal oscillator may be exposed in this area ( top and bottom ),
however it has no affect on the performance of the device.
2)
Pattern (GND, power line, signal line, soldering pattern, etc) is not allowed.
In this area, at a parts side of board, do not pattern layout surely.
In an area (
) of the product bottom side, a terminal connected to an IC inside is exposed.
When the circuit pattern contacts those terminal, it will cause serious obstruction to the oscillation,
function or electronic spec.
3)
It is the best design that there is no signal line in this area.
Please fill it up with GND pattern if possible.
