The ZC702 Evaluation Board for the Zynq-7000 XC7Z020 AP SoC User Guide v1.0 (UG850), lists the PPM frequency jitter as 20 ppm.
However, the data sheet for the SiT9102AI-243N25E200.00000 oscillator, described in UG850, lists a frequency stability of 50 ppm.
Which value is correct?
The data sheet for the SiT9102AI-243N25E200.00000 is correct; the PPM frequency jitter for the SiT9102 device used on the ZC702 Evaluation Board is 50 ppm.
The ZC702 Evaluation Board for the Zynq-7000 XC7Z020 AP SoC User Guide v1.1 (UG850) has been updated with the correct frequency stability figure.
