Thanks for very good info!.
Unfortunately my AD9524 behaves differently. When AD9524 doesn't have any power to it I could measure 1.75mA current going into the AD9524 SDA pin from the i2c bus which is powered. At the same time the voltage at…
> Can I use the AD9524 in zero delay mode just by routing OUT0 to ZD_IN, and without writing anything to the chip?
No. You'll need to program the chip. However, you can store those values in an EEPROM inside the AD9524 so that the AD9524…
Hi All !!!
It's a pity, but all Russian support guidance was useless. VCXO calibration is failed, PLL2 feedback clock is absent.
Moreover i found one more AD9524 bug. My AD9524 SPI controller can die at power-up. Especially after heating up to…
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…
I set AD9524 in power-down mode register 0x233 as follow:
power ON my PCBA (0x233 = 0x07 default) --> switch to normal operation(0x233 = 0x00) -->power-down (0x233 = 0x07) --> normal operation(0x233 = 0x00) success on most PCBA.
But a few…
The correct range of the internal VCO on the AD9524 is 3600MHz - 4000MHz.
The range shown in ADIsimCLK v1.4 needs to be updated for the AD9524.
Please let me know if there is anything else I can do to help.
Does ADI have a list of VCXOs that have been tested with the AD9524? I have a customer looking for what VCXOs besides the one in the eval board that ADI has validated with the AD9524.
In the datasheet of AD9524 , page 18, it mentions that "VCXO is from 15MHz to 250MHz".
SO, a 10MHz VCXO can not be used with AD9524?
Thank you in advance!
We want to use AD9524 in i2c mode so we have two 10K pull-up resistors on STATUS0/SP0 and STATUS1/SP1 pins.
According with the datasheet there are 40K pull-down internal resistors on those pins, however those pins will never go high not even when we…
I have chosen the AD9524 for a new design, are there any common issues or problems I should be aware of to improve my chances of building a successful design the first time? Any other parts I should consider instead?
