PIN FUNCTIONS
DOUBLE DATA RATE LVDS OUTPUT MODE
All Pins Below Have LVDS Output Levels. The Output
Current Level is Programmable. There is an Optional
Internal 100Ω Termination Resistor Between the Pins
of Each LVDS Output Pair.
D0_1–/D0_1+ to D10_11–/D10_11+ (Pins 19/20, 21/22,
23/24, 29/30, 31/32, 33/34): Double Data Rate Digital
Outputs. Two data bits are multiplexed onto each differential
output pair. The even data bits (D0, D2, D4, D6, D8, D10)
appear when CLKOUT+ is low. The odd data bits (D1, D3,
D5, D7, D9, D11) appear when CLKOUT+ is high.
CLKOUT–/CLKOUT+ (Pins 27/28):
Data Output Clock.
The digital outputs normally transition at the same time
as the falling and rising edges of CLKOUT+. The phase of
CLKOUT+ can also be delayed relative to the digital outputs
by programming the mode control registers.
OF–/OF+ (Pins 35/36):
Over/Under Flow Digital Output. OF+
is high when an overow or underow has occurred.
