I am using LS1043A on my board and want to enable WDOG in my system (custom board) so I need to connect a 32kHz oscillator to RTC Pin and pull down TA_BB_RTC Pin to ground. I am not getting 32kHz oscillator with most of the Oscillator vendor and do not have any timer device to support lower clock. My system input clock is 100MHZ. is it must to connect only 32kHz or any other clock will work?
"The minimum period of the RTC signal should be greater than or equal to 16x the period of the platform clock with a 50% duty cycle. There is no minimum RTC frequency"
