DESCRIPTION
The PLL620-28/-29 family of XO ICs is specifically
designed to work with high frequency fundamental
and third overtone crystals. They achieve very low
current into the crystal, resulting in better stability.
Their very low jitter makes them ideal for the most
demanding timing requirements.
