Hello,
When an 40 MHz external clock is used as frequency reference to feed an AC-coupled sinewave, what is the impedance seen on the CLKP node of the AWR2243P chipset ?
The clock has to be loaded with a 50 Ohms charge. Is the chipset impedance high enough to simply add a 50 Ohm termination resistance between CLKP and GND (in addition to an AC-coupling series capacitor)? Otherwise, what impedance should be considered?
Best regards,
Jeff
