CY2305SXC-1T

Cypress Semicon · Clock Buffers, Drivers · SOIC-8

CY2305SXC-1T from Cypress Semicon, in a SOIC-8. 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 REF input Input reference frequency that the on-chip PLL locks to; 5-V tolerant input with a weak pull-down and a threshold of VDD/2.
2 CLK2 output Buffered clock output with a weak pull-down.
3 CLK1 output Buffered clock output with a weak pull-down.
4 GND power_in Ground supply pin.
5 CLK3 output Buffered clock output with a weak pull-down.
6 VDD power_in 3.3-V supply; the operating supply range is 3.0 V to 3.6 V.
7 CLK4 output Buffered clock output with a weak pull-down.
8 CLKOUT output Buffered clock output that also serves as the internal PLL feedback pin; for zero input-output delay its load must equal the other outputs' load.

  • Symbol: CY2305SXC-1T
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOIC-8 (KiCad packages3D, STEP)
  • 3D model files: cy2305sxc-1t-etched.step / cy2305sxc-1t-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); cy2305sxc-1t.step / cy2305sxc-1t.glb are the bare package body.
