GA1087 Overview
The core of the GA1087 is a Phase-Locked Loop (PLL) that continuously pares the reference clock (REFCLK) to the feedback clock (FBIN), maintaining a zero frequency difference between the two. Since one of the outputs (Q0 Q8) is always connected to FBIN, the PLL keeps the propagation delay between the outputs and the reference clock within 350 ps +500 ps for the GA1087-MC500, and within 350 ps +700 ps for the...
