S3225SMD27MOSC

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.
