Other Parts Discussed in Thread: AM3359,
Hi Experts,
My customer has a Gigabit PHY that is time synchronized using IEEE-1588. It outputs a 1 Hz Pulse Per Second. They would like to synchronize their 25 MHz system clock to this PPS signal.They plan to run our AM3359 PRU Real Time Ethernet at 8 KHz. The PRU SYNC0 signal run through a PLL on each device. This is programmed to produce a configurable clock, depending on the slave device type and conversion rates. (600KHz - 8.192 MHz). The PRU will keep the slave devices from drifting apart, but the PRU itself will drift with respect to the grandmaster time unless it is driven with a PTP disciplined clock.
I looked at the LMK05028 synchronizer clock, but I don’t have much experience with these advanced PLL chips.
Any recommendations? (Preferably small form factor)
Thanks,
Connie
