If you can use GPIO20 (CLOCK GPIN0) or GPIO21 (CLOCK GPIN1) as input and (assuming a Pico) GPIO23 (CLOCK GPOUT1) as output then you could maybe use a clock generator; see 2.15 Clocks in the RP2040 datasheet (in particular: 2.15.6.4 Configuring a GPIO input clock, 2.15.6.3 Configuring a GPIO output clock, 2.15.6.1 Configuring a clock generator).
