DESCRIPTION

+5V Power.

Ground.

Clock Input. (CMOS LEVEL). fS is the frequency of CLK

Input Data Bus A. AIN0 is the LSB. Input data format is 16-bit Two’s Complement.

Input Data Bus B. BIN0 is the LSB. Input data format is 16-bit Two’s Complement.

The Mode Select Inputs set one of four operational modes as highlighted in Table 1.

The Internal\External multiplexer select inputs set whether the data multiplex/demultiplex function required in the various

operational modes is performed internally (High State) or externally to the chip (Low State).

This input is used to synchronize the input sample stream with the zero degree phase of the up or down convert Local

Oscillators. In the straight decimate modes, this input can be use to synchronize the input sample stream with a particular

phase of the halfband filter. (See the Operational Modes Section for additional information).

The Upper and Lower Sideband select line is used to specify the direction of frequency translation imparted on the data

stream in the Down Convert and Decimate Mode and in the Quadrature to Real Convert Mode. (See Operational Modes

Section for additional information).

The Round Select inputs set the number of output bits from eight (RND = 000) to sixteen (RND = 110). Least significant

output bits are zeroed. See Table 4.

Three-State Control Output Bus A, OUTA0-15. Active Low.

Three-State Control Output Bus B, OUTB0-15. Active Low.

The Format select input is used to convert the two’s complement output to offset binary (unsigned). When asserted high,

the AOUT15 and BOUT15-bits are inverted from the normal two’s complement representation.

Output Bus A. AOUT0 is the LSB.

Output Bus B. BOUT0 is the LSB.
