GA1085 Product details

Description

The core of the GA1085 is a Phase-Locked Loop (PLL) that continuously compares the reference clock (REFCLK) to the feedback clock (FBIN), maintaining a zero frequency difference between the two. Q8) is always connected to FBIN, the PLL keeps the propagation delay between the outputs and the reference clock within 350 ps +1000 ps.

Features

Wide frequency range: 24 MHz to 105 MHz.
Output configurations: Four outputs at fREF Four outputs at fREF /2 Two outputs at fREF /2 ␣ ␣ ␣ ␣ with adjustable phase ␣ ␣ ␣ ␣ ␣ ␣ ␣ ␣ ␣ ␣ ␣ or Five outputs at 2x fREF Three outputs at fREF Two outputs at fREF ␣ ␣ ␣ ␣ with adjustable phase.
Selectable Phase Shift:.
2t,.
t, +t, and +2t (t = 1/fVCO).
Low output-to-output skew: 150 ps (max) within a group.
Near-zero propagation delay:.
3.
