In-Phase Input. Data input for in-phase (real) samples. Format may be either two’s complement or offset binary format
(see I/O Formatting/Control Register in Table 9). IIN9 is the MSB.
Quadrature Input. Data input for quadrature (imaginary) samples. Format may be either two’s complement or offset bi-
nary format (see I/O Formatting/Control Register in Table 9). QIN9 is the MSB.
Input Enable. When ENI is active ‘low’, data on IIN9-0 and QIN9-0 is clocked into the processing pipeline by the rising
edge of CLK. This input also controls the internal data processing as described in the Input Controller Section of the
data sheet. ENI is active ‘low’.
Carrier Phase Offset. The phase of the internally generated carrier frequency may be shifted by 0, 90, 180, or 270 de-
grees by controlling these pins (see Synthesizer/Mixer Section). The phase mapping for these inputs is given in Table 1.
Carrier Frequency Load. This input loads the Carrier Frequency Register in the Synthesizer NCO (see
Synthesizer/Mixer Section). When this input is sampled ‘high’ by clock, the contents of the Microprocessor Interface
Holding Registers are transferred to the carrier frequency register in the Synthesizer NCO (see Microprocessor Inter-
face Section). NOTE: This pin must be ‘low’ when loading other configuration data via the Microprocessor In-
terface. Active high Input.
Carrier Offset Frequency Input. This serial input is used to load the Carrier Offset Frequency into the Synthesizer NCO
(see Serial Interface Section). The new offset frequency is shifted in MSB first by CLK starting with the clock cycle after
the assertion of COFSYNC.
Carrier Offset Frequency Sync. This signal is asserted one CLK cycle before the MSB of the offset frequency data word
(see Serial Interface Section).
