Test reset. Active low. If JTAG not used, tie this pin low. If there is a trace connected to the pin and
there is enough board noise, the JTAG port might get into an unexpected state and stop
communications with the part
OUTPUTS
Aout(15:0)
O
Parallel Data Output bus A. A 16-bit parallel data output which can be programmed to consist of I, Q,
AGC. Data from Channels 0, 1, 2 and 3 can be multiplexed into a common parallel output data bus.
Information can be sequenced in a programmable order. Can be ones complemented. Can be
divided into two 8-bit busses.
See Data Output Formatter Section and Microprocessor Interface
Section. See Table 24.
Bout(15:0)
O
Parallel Data Output bus B. A 16-bit parallel data output which can be programmed to consist of I, Q,
AGC. Data from Channels 0, 1, 2 and 3 can be multiplexed into a common parallel output data bus.
Information can be sequenced in a programmable order. Can be ones complemented. Can be
divided into two 8-bit busses.
See Data Output Formatter Section and Microprocessor Interface
Section.
Cout(15:0)
O
Parallel Data Output bus C. A 16-bit parallel data output which can be programmed to consist of I, Q,
AGC. Data from Channels 0, 1, 2 and 3 can be multiplexed into a common parallel output data bus.
Information can be sequenced in a programmable order. Can be ones complemented. Can be
divided into two 8-bit busses.
See Data Output Formatter Section and Microprocessor Interface
Section.
Dout(15:0)
O
Parallel Data Output bus D. A 16-bit parallel data output which can be programmed to consist of I, Q,
AGC. Data from Channels 0, 1, 2 and 3 can be multiplexed into a common parallel output data bus.
Information can be sequenced in a programmable order. Can be ones complemented. Can be
divided into two 8-bit busses.
See Data Output Formatter Section and Microprocessor Interface
Section.
Below is the table of the serial output bits allocation for DOUT.
Eout(15:0)
O
A 16-bit parallel VGA/Attenuator control output. Partitionable into separate 4 or 8-bit busses.
CLKO1
O
Output Clock 1. Can be programmed to be at CLKC/N for N = 1 to 16. The polarity of CLKO1 is
programmable.
CLKO2/
INTRPT
O
Available ONLY on Rev B (final) version of the part. Provides a complementary output or a second
clock to simplify board routing. Polarity is programmable. It can also be programmed as an interrupt
from one or more channels for a sequenced read (FIFO-like) mode.
