APSI
Description
Peak-to-peak Intrinsic Jitter of the Output
APS ports, APSO[1:0]+/, measured over a
60 second interval with bandpass filter.
The bandpass filter has a 250 KHz high-
pass cutoff frequency with a roll-off of 20
dB/decade and a low-pass cutoff frequency
of 5 MHz.
Peak-to-peak Jitter Tolerance of the Input
APS ports, APSI[1:0]+/-, for the following
Jitter frequencies:
10 Hz – 30 Hz
30 Hz – 300 Hz (-20dB/decade roll-off)
300 Hz – 25 KHz
25 KHz – 375 KHz (-20dB/decade roll-off)
375 KHz – 5 MHz
Peak-to-peak Wander Tolerance of the
Input APS ports, APSI[1:0]+/-.
Input APS port wander is a result of phase
noise or transient between the APS port
timings of the Working and Protect devices.
The same reference clock must be
provided to both devices for proper APS
port operation.
