PLL_EN
PLL is bypassed and disabled. The PECL
clock reference source drives the outputs
through the divider blocks
PLL enabled. Normal operation. VCO out-
put drives the outputs through the divider
blocks
1
BYPASS
Complete bypass of the PLL and divider
blocks. PECL reference clocks the outputs.
Normal operation. Dividers selected.
