Description
15
I
3.3 V CMOS
CS
Serial Control Port Chip Select; Active Low. This pin has an internal 30 kΩ
pull-up resistor.
16
I
3.3 V CMOS
SCLK/SCL
Serial Control Port Clock Signal. This pin has an internal 30 kΩ pull-down resistor
in SPI mode but is high impedance in IC mode.
17
I/O
3.3 V CMOS
SDIO/SDA
Serial Control Port Bidirectional Serial Data In/Out.
18
O
3.3 V CMOS
SDO
Serial Control Port Unidirectional Serial Data Out.
19, 59
I
GND
Ground Pins.
20
I
Three-level
logic
SP1
Select SPI or IC as the serial interface port and select the IC slave address in IC
mode. Three-level logic. This pin is internally biased for the open logic level.
21
I
Three-level
logic
SP0
Select SPI or IC as the serial interface port and select the IC slave address in IC
mode. Three-level logic. This pin is internally biased for the open logic level.
22
I
3.3 V CMOS
EEPROM
Setting this pin high selects the register values stored in the internal EEPROM to
be loaded at reset and/or power-up. Setting this pin low causes the AD9522 to
load the hard-coded default register values at power-up/reset. This pin has an
internal 30 kΩ pull-down resistor.
23
I
3.3 V CMOS
RESET
Chip Reset, Active Low. This pin has an internal 30 kΩ pull-up resistor.
24
I
3.3 V CMOS
PD
Chip Power-Down, Active Low. This pin has an internal 30 kΩ pull-up resistor.
