1. Guaranteed by simulation and characterization.
2. Because the serializer is in tri-state mode, the deserializer will lose PLL lock and have to resynchronize before
data transfer.
Deserializer Electrical Characteristics
AVDD = DVDD = 3V to 3.6V, TAMB = -40°C to +85°C, RLOAD=28Ω, CLOAD = 15pF, Receiver Input Range: 0V to 2.4V,
typical values @ TAMB = +25°C and VDD = 3.3V (unless otherwise specified).
