I'm using AD9524 with fixed VCO CMOS generator. My scheme look like this http://ez.analog.com/thread/7746?tstart=1
All powers +1.8/3.3 V is good, VCO get good clear clock, SPI of AD9524 is worked, but when i read status register at adress 0x22C, there is "0000_0000". AD9524 don't see clock at OSC_IN port at all %(
Port EEPROM_SEL connected to GND, PD/SYNC/RESET is left unconnected, but use internal pullup (i checked it).
Is there any special features/register/etc that i must do to initialize AD9524?
Thanks's a lot.
