Q: The MAX3890 specifies acceptable input parallel clocks of 155.52MHz, 77.76MHz,
51.84MHz, and 38.88MHz. Is it possible to use the chip with other clock frequencies such as 96MHz?
A: No other rates are operable due to the use of a PLL inside the IC that only operates at 2.488GHz. The internal PLLs in the MAX3890 and MAX3885 are designed for the target application of 2.488Gbps, and they perform this very well.
