DESCRIPTION
The PLL620-0x family of XO IC’s is specifically
designed to work with high frequency fundamental
and third overtone crystals. Their low jitter and low
phase noise performance make them well suited for
high frequency XO requirements. They achieve very
low current into the crystal resulting in better overall
stability.
