Description
1
IRQ
O
3.3 V CMOS
Interrupt Request Line.
2
SCLK/SCL
I
3.3 V CMOS
Serial Programming Clock (SCLK) in SPI Mode. Data clock for serial programming.
Open-Collector Serial Clock Pin (SCL) in I2C Mode. Requires a pull-up resistor, usually
2.2 k; the resistor size depends on the number of I2C devices on the bus.
3
SDIO/SDA
I/O
3.3 V CMOS
Serial Data Input/Output (SDIO) in SPI Mode. When the device is in 4-wire SPI mode,
data is written via this pin. In 3-wire SPI mode, both data reads and writes occur on
this pin. There is no internal pull-up/pull-down resistor on this pin.
Open-Collector Serial Data Pin (SDA) in I2C Mode. Requires a pull-up resistor, usually
2.2 k; the resistor size depends on the number of I2C devices on the bus.
4
SDO
O
3.3 V CMOS
Serial Data Output. Use this pin to read data in 4-wire mode. There is no internal pull-up/
pull-down resistor on this pin. This pin is high impedance in the default 3-wire mode.
5
AA
CSEE
I
3.3 V CMOS
Chip Select (SPI), Active Low. When programming a device, this pin must be held low.
In systems where more than one AD9558 is present, this pin enables individual
programming of each AD9558. This pin has an internal 10 k pull-up resistor.

Power
1.8 V Digital Supply.
7
AVDD
I
Power
1.8 V Analog (SYSCLK) Power Supply.
8
XOA
I
Differential
input
System Clock Input. XOA contains internal dc biasing and should be ac-coupled with
a 0.01 μF capacitor, except when using a crystal. If a crystal is used, connect the crystal
across XOA and XOB. Single-ended 1.8 V CMOS is also an option but can introduce
a spur if the duty cycle is not 50%. When using XOA as a single-ended input, connect
a 0.01 μF capacitor from XOB to ground.
9
XOB
I
Differential
input
Complementary System Clock Input. Complementary signal to XOA. XOB contains
internal dc biasing and should be ac-coupled with a 0.01 μF capacitor, except when
using a crystal. If a crystal is used, connect the crystal across XOA and XOB.

AVDD
I
Power
1.8 V Analog (VCO) Power Supply.
11
NC
I
No Connection. Do not connect to this pin.
