PRELIMINARY TECHNICAL DATA
36
RESET
AD9953
I
Active high hardware reset pin. Assertion of the RESET
pin forces the AD9953 to the initial state, as described in
the IO Port Register map.
Asynchronous active high reset of the serial port
controller. When high, the current IO operation is
immediately terminated enabling a new IO operation
to commence once IOSYNC is returned low
When operating the I/O port as a 3-wire serial port
this pin serves as the serial data output. When
operated as a 2-wire serial port this pin is the unused
and can be left unconnected.
This pin functions as an active low chip select that
allows multiple devices to share the IO bus.
This pin functions as the serial data clock for IO
operations
I/O
When operating the I/O port as a
3-wire
serial port
this pin serves as the serial
data input
, only. When
operated as a
2-wire
serial port this pin is the
bi-
directional serial data
pin.
I
Digital power supply (for IO cells only, 3.3v optional)
I
Input signal used to synchronize multiple AD9953s.
This input is connected to the SYNC_CLK output of
a different AD9953.
O
Clock output pin, which serves as a synchronizer for
external hardware.
I
Input pin used to control the direction of the Shaped
On-Off Keying function when programmed for
operation. OSK is synchronous to the SYNC_CLK
pin. When OSK is not programmed, this pin should
be tied to DGND.
I
Input pins used to select one of the four internal
profiles. Profile<1:0>are synchronous to the
SYNC_CLK pin. Any change in these inputs
transfers the contents of the internal buffer memory
to the IO Registers (sends an internal I/O
UPDATE).
