Clock Supply Common
Differential Clock Input
Differential Clock Input
With the PLL enabled, this pin indicates the state of the PLL. A read of a
Logic “1” indicates the PLL is in the locked state. Logic “0” indicates the
PLL has not achieved lock. This pin may also be programmed to act as
either an input or output (Address 02h, Bit 3) DATACLK signal running at
the input data rate.
Digital Common
Digital Supply Voltage
P1B15 (MSB) to P1B0 (LSB) Port “1” Data Inputs
IQSEL/P2B15 (MSB)
In “1” port mode, IQSEL = 1 followed by a rising edge of the differential
input clock will latch the data into the I channel input register. IQSEL = 0
will latch the data into the Q channel input register. In “2” port mode, this
pin becomes the port “2” MSB.
ONEPORTCLK/P2B14
With the PLL disabled and the AD9777 in “1” port mode, this pin becomes
a clock output that runs at twice the input data rate of the I and Q channels.
This allows the AD9777 to accept and demux interleaved I and Q data to
the I and Q input registers.
P2B13 to P2B0 (LSB)
Port “2” Data Inputs
SPI_SDO
In the case where SDIO is an input, SDO acts as an output. When SDIO
becomes an output, SDO enters a High-Z state.
SPI_SDIO
Bidirectional Data Pin. Data direction is controlled by Bit 7 of Register
Address 00h. The default setting for this bit is “0,” which sets SDIO as an input.
SPI_CLK
Data input to the SPI port is registered on the rising edge of SPI_CLK.
Data output on the SPI port is registered on the falling edge.
SPI_CSB
Chip Select/SPI Data Synchronization. On momentary logic high, resets
SPI port logic and initializes instruction cycle.
RESET
Logic “1” resets all of the SPI port registers, including Address 00h, to their
default values. A software reset can also be done by writing a Logic “1” to
SPI Register 00h, Bit 5. However, the software reset has no effect on the bits
in Address 00h.
