Webb12 juli 2016 · If the PLL is not locking and you cannot read back from it, try sending software commands that require a minimum amount of hardware commands to work. One possibility is to power the PLL up and down via software (not pin) and look for a predictable current change or bias-voltage-level change on a pin. Webb27 juli 2009 · 5,585. pll did not lock. I am simulating the PLL, and I am bread boarding nothing. I am simulating the PLL for a long time, so no problem with this. The VCo control voltage oscillates around its "correct" value for a some time, but drops to zero all of a sudden. The reason, I think is the loop filter, I will send the VCO control voltage soon. parrocchia monfortani monte mario

"WebbPLL Configuration For each serial transceiver channel, there is a ring PLL called channel PLL (CPLL). The UltraScale GTY architecture has two additional shared PLLs per quad, QPLL0 and QPLL1. These PLLs are shared to support high-speed, high-performance, and low-power multi-lane applications. Figure1-1 shows a Quad in the UltraScale architecture. " - Ibert pll not locked
