SDI(Pin60):SerialInterfaceDataInput.Inserialprogram-
ming mode, (PAR/SER = 0V), SDI is the serial interface
data input. Data on SDI is clocked into the mode control
registers on the rising edge of SCK. In the parallel pro-
gramming mode (PAR/SER = VDD), SDI selects 3.5mA or
1.75mA LVDS output current (see Table 2). SDI can be
driven with 1.8V to 3.3V logic.
SCK (Pin 61): Serial Interface Clock Input. In serial
programming mode, (PAR/SER = 0V), SCK is the serial
interface clock input. In the parallel programming mode
(PAR/SER = VDD), SCK can be used to place the part in the
low power sleep mode (see Table 2). SCK can be driven
with 1.8V to 3.3V logic.
CS (Pin 62): Serial Interface Chip Select Input. In serial
programming mode, (PAR/SER = 0V), CS is the serial in-
terface chip select input. When CS is low, SCK is enabled
for shifting data on SDI into the mode control registers.
In the parallel programming mode (PAR/SER = VDD), CS
controls the clock duty cycle stabilizer (see Table 2). CS
can be driven with 1.8V to 3.3V logic.
PAR/SER (Pin 63): Programming Mode Selection Pin.
Connecttogroundtoenabletheserialprogrammingmode
where CS, SCK, SDI, SDO become a serial interface that
control the A/D operating modes. Connect to VDD to en-
able the parallel programming mode where CS, SCK, SDI
become parallel logic inputs that control a reduced set of
the A/D operating modes. PAR/SER should be connected
directly to ground or the VDD of the part and not be driven
by a logic signal.
LVDS Outputs
The following pins are differential LVDS outputs. The
output current level is programmable. There is an optional
internal 100 termination resistor between the pins of
each LVDS output pair.
OF–/OF+ (Pins 22/23): Over/Underflow Digital Output.
OF+ is high when an overflow or underflow has occurred.
The overflows for channel A and channel B are multiplexed
together.
DB0_1–/DB0_1+ to DB12_13–/DB12_13+ (Pins 24/25, 26/27,
28/29, 30/31, 34/35, 36/37, 38/39): Channel B Double
Data Rate Digital Outputs. Two data bits are multiplexed
onto each differential output pair. The even data bits (DB0,
DB2,DB4,DB6,DB8,DB10,DB12)appearwhenCLKOUT+
islow.Theodddatabits(DB1,DB3,DB5,DB7,DB9,DB11,
DB13) appear when CLKOUT+ is high.
CLKOUT–/CLKOUT+ (Pins 40/41): 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.
DA0_1–/DA0_1+ to DA12_13–/DA12_13+ (Pins 42/43, 44/45,
46/47, 50/51, 52/53, 54/55, 56/57): Channel A Double
Data Rate Digital Outputs. Two data bits are multiplexed
onto each differential output pair. The even data bits (DA0,
DA2,DA4,DA6,DA8,DA10,DA12)appearwhenCLKOUT+
islow.Theodddatabits(DA1,DA3,DA5,DA7,DA9,DA11,
DA13) appear when CLKOUT+ is high.
