CDCS503PWR from Texas Instruments, in a TSSOP-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 | IN | input | LVCMOS clock input with frequency range 8-32 MHz (FS=0) or 8-27 MHz (FS=1). |
| 2 | SSC_SEL 0 | input | Spread spectrum selection input with internal pull-up, bit 0 of spread amount (±0%, ±0.5%, ±1%, ±2%). |
| 3 | SSC_SEL 1 | input | Spread spectrum selection input with internal pull-up, bit 1 of spread amount (±0%, ±0.5%, ±1%, ±2%). |
| 4 | GND | power_in | Ground reference. |
| 5 | FS | input | Frequency multiplication selection input with internal pull-up; low (0) selects x1 mode, high (1) selects x4 mode. |
| 6 | OUT | output | LVCMOS clock output with frequency 8-32 MHz (x1 mode) or 32-108 MHz (x4 mode) depending on FS and input frequency. |
| 7 | OE | input | Output enable input with internal pull-up; low (0) sets output to high impedance, high (1) enables output. |
| 8 | VDD | power_in | 3.3V power supply with operating voltage range 3.0-3.6V. |
