SST · Crystal Oscillators · SMD3225-4P
S3225SMD27MOSC from SST, in a SMD3225-4P. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | INHB | input | Output state control (tri-state) pin: 'H' or open selects normal oscillator output, 'L' puts the output in tri-state (high impedance), and it must not be connected to ground or the oscillator goes high impedance. |
| 2 | Vss | power_in | Ground (地) pin for the oscillator. |
| 3 | QOUT | output | Oscillator clock output: normal oscillator output when enabled, high impedance when INHB is low; HCMOS output low max 10%VDD, high min 90%VDD, rated for 15pF/HCMOS/TTL load. |
| 4 | VDD | power_in | Supply voltage pin, rated 3.3V±10% or 1.8V±10% per the datasheet's operating voltage specification. |
