PIN FUNCTIONS
Digital Outputs
For CMOS Mode, Full Rate or Demultiplexed
DA0 to DA15 (Pins E9 to H5): Digital Outputs, A Bus.
DA15 is the MSB. Output bus for full rate CMOS mode
and demultiplexed mode.
CLKOUTA (Pin E8): Inverted Data Valid Output. CLKOUTA
will toggle at the sample rate in full rate CMOS mode or
at 1/2 the sample rate in demultiplexed mode. Latch the
data on the rising edge of CLKOUTA.
OFB (Pin E6): Overfl ow/Underfl ow Digital Output for the
B Bus. OFB is high when an overfl ow or underfl ow has
occurred on the B bus. OFB is in a high impedance state
in full rate CMOS mode.
DB0 to DB15 (Pins B5 to D9): Digital Outputs, B Bus. DB15
is the MSB. Active in demultiplexed mode. The B bus is in
a high impedance state in full rate CMOS mode.

CLKOUTB (Pin E7): Data Valid Output. CLKOUTB will toggle
at the sample rate in full rate CMOS mode or at 1/2 the
sample rate in demultiplexed mode. Latch the data on the
falling edge of CLKOUTB.
OFA (Pin G5): Overfl ow/Underfl ow Digital Output for the
A Bus. OFA is high when an overfl ow or underfl ow has
occurred on the A bus.
For LVDS Mode, Standard or Low Power

puts. All LVDS outputs require differential 100Ω termination
resistors at the LVDS receiver. D15
CLKOUT
