SCEYR12X0000018VRM from SST, in a SMD2520-4P. 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 enable): 'H' or open selects normal oscillator output, while 'L' puts QOUT in tri-state (high impedance); this pin must not be grounded, otherwise the oscillator is high impedance. |
| 2 | VSS | power_in | Ground (地) reference pin for the oscillator supply. |
| 3 | QOUT | output | Oscillator output at 12.000 MHz, 15 pF HCMOS/TTL compatible load, with rise/fall time of 8 ns max. and duty cycle of 40%-60%; high impedance when INHB is low. |
| 4 | VDD | power_in | Supply voltage pin, rated 3.3 V ±10% or 1.8 V ±10% per the operating voltage specification. |
