4. With VCO_Sel = ‘0’, the PLL will be unstable with a
÷2, ÷4 or ÷6 feedback ratio. With VCO_Sel = ‘1’, the PLL will be unstable with a ÷2 feedback
ratio.
5. tpd is specified for 50MHz input reference FB ÷8. The window will shrink/grow proportionally from the minimum limit with shorter/longer input
reference periods. The tpd does not include jitter.
