EVALUATION PC BOARD
The evaluation board is useful for your design and to have more understanding of the usage and performance of
this device. This circuit is the same as TEST CIRCUIT. Note that this board is not prepared to show the
recommendation of pattern and parts layout.
Circuit Diagram
Note:
1. This board is designed for mixer-input type and C2 is factory-configured as follows:
C2 : in the B position
For the case of IF-input type, the position of C2 is necessary to change as follows:
C2 : in the A position
The actual position of C2 is shown in the next page.
