Pin | Name | I/O | Description |
|---|
| 1 | OSCIN | I | The connection terminal of the crystal oscillator and the capaitors
It is possible to input a clock from outside, too, from OSCIN. |
| 2 | OSCOUT | O |
| 3 | fv | O | The output terminal of the comparison frequency divider |
| 4 | VDD | - | The power supply terminal |
| 5 | DOP | O | The lowpass filter connection terminal (For the passive) |
| 6 | VSS | - | The grounding terminal |
| 7 | LD | O | The output terminal of the phase comparator
When locking, it outputs "H" and when the lock comes, it outputs " negative pulse ". |
| 8 | fIN | I | The comparison frequency input terminal
(It makes an AC connection). |
| 9 | Clock | I | The clock input terminal of the data which sets a dividing ratio
It reads data in the rise of the clock pulse. |
| 10 | Data | I | The input terminal of the data which sets a dividing ratio |
| 11 | LE | I | The load enable input terminal
It sends the contents of Data to the side of the reference or the side of the comparison in the combination with the control bit of Data at the time of LE=H. |
| 12 | DOA | O | The connection terminal of the lowpass filter (For the activist) |
| 13 | fr | O | The output terminal of the reference frequency divider |
| 14 | NC | - | Test (Factory test) |
| 15 | fV | O | The lowpass filter connection terminal (For the differential-type filter) |
| 16 | fR | O |
