Problem
Can I use the external PLL option when implementing the altlvds megafunction with a deserialization factor of 2?
Solution
No, when you have a deserialization factor of 2, the SERDES is bypassed and the functionality is implemented in double data rate (DDR) registers. You need at least a deserialization factor of 4 to use the external PLL option.
