CDCS503PWR

Texas Instruments · Clock Buffers, Drivers, Distributors · TSSOP-8

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.
