57.4.8 3 MHz-20 MHz XIN Clock Input Characteristics in Bypass Mode
| Symbol | Parameter | Conditions | Min. | Typ. | Max. | Unit |
|---|---|---|---|---|---|---|
| 1/(tCPXIN) | XIN Clock Frequency | (see Note 1) | – | – | 20 | MHz |
| tCHXIN | XIN Clock High Half-period | (see Note 1) | 25 | – | – | ns |
| tCLXIN | XIN Clock Low Half-period | (see Note 1) | 25 | – | – | ns |
| VXIN_IL | VXIN Input Low-level Voltage | (see Note 1) | Min of VIL for CLOCK pad | – | Max of VIL for CLOCK pad | V |
| VXIN_IH | VXIN Input High-level Voltage | (see Note 1) | Min of VIH for CLOCK pad | – | Max of VIH for CLOCK pad | V |
Note: 1.These characteristics are applicable
only when the 3 MHz-20 MHz crystal oscillator is in Bypass mode.
