JIT_NL - Negative Peak Jitter Measurement Low-Byte Register
JIT_NH - Negative Peak Jitter Measurement High-Byte Register
Address: 7E8H
Type: Read
Default Value: 00H
Bit
Name
Description
7 - 0
JIT_N[7:0]
These bits, together with the JIT_N[11:8] bits, reflect the greatest negative peak value of the demodulated jitter signal which is
measured by channel 0. They are updated automatically or manually, as determined by the JM_MD bit (b1, JM). They should be
read in the next round of jitter measurement; otherwise, they will be overwritten.
The relationship between the greatest negative peak value and the indication in these bits is:
Negative Peak = [JIT_NH, JIT_NL] / 16 (UIpp)
Address: 7E9H
Type: Read
Default Value: 00H
