CY22381FXIT

Infineon Cypress Semicon · Clock Generators, PLLs, Frequency Synthesizers · SOIC-8

CY22381FXIT from Infineon Cypress Semicon, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 CLKC output Configurable clock output C sourced from crosspoint switch through programmable 7-bit post divider, maximum frequency 166 MHz.
2 GND power_in Ground reference.
3 XTALIN input Reference crystal input for 8-30 MHz crystals or external reference clock input up to 150 MHz.
4 XTALOUT output Reference crystal oscillator feedback output; leave floating if XTALIN is driven by external reference clock.
5 CLKB output Configurable clock output B sourced from crosspoint switch through programmable 7-bit post divider, maximum frequency 166 MHz.
6 CLKA output Configurable clock output A sourced from crosspoint switch through programmable 7-bit post divider, maximum frequency 166 MHz.
7 VDD power_in Power supply input, nominal 3.3V with operating range 3.135V to 3.465V.
8 FS/SUSPEND/OE/SHUTDOWN input Programmable general purpose input for frequency select, suspend mode, output enable (three-states outputs when LOW), or full-chip shutdown when LOW.
