1. Outline

The PCA7750G02 is a converter board from 80-pin 0.8-mm-pitch LCC (80D0) to standard-pitch
(2.54-mm). The pins correspond one-to-one.

2. Pattern of Oscillator Circuits

Figure 1 shows the oscillator circuit pattern. The holes 26 to 32 correspond to the pattern numbers
of the S1.

3. Connecting the Oscillator Circuit Pattern

Take notice that the processing depends on whether or not the IC1 (oscillator module) is used.

(1) When the IC1 (oscillator module) is used

Recommended oscillator module: SG-51P (Seiko Epson Corporation)

When using the IC1, the following processing is necessary (see (1) to (3) in Figure 2).

(1) Supply VCC and GND.

(2) Connect the OUT pin to the XIN pin of the S1.

(3) Install a bypass capacitor at the C1.
