Halfband Filter
The HSP43216 Halfband Filter addresses a wide variety of applications by combining fS/4 (fS = sample frequency) quadrature up/down convert circuitry with a fixed coefficient halfband filter processor as shown in the block diagram. These elements may be configured to operate in one of the four following modes: decimate by 2 filtering of a real input signal; interpolate by 2 filtering of a real input signal; fS/4 quadrature down conversion of a real input signal followed by decimate-by-2 filtering to produce a complex analytic signal; interpolate-by-2 filtering of a complex analytic signal followed by fS/4 quadrature up conversion to produce a real valued output. The frequency response of the HSP43216's halfband filter has a shape factor, (passband+transition band)/passband, of 1.24:1 with 90dB of stopband attenuation. The passband has less than 0.0003dB of ripple from 0fS to 0.2fS with stopband attenuation of greater than 90dB from 0.3fS to Nyquist. At 0.25fS the filter provides 6dB of attenuation. The HSP43216 processes data streams with word widths up to 16 bits and data rates up to 52 MSPS. The processing throughput of the par t is easily doubled to rates of up to 104 MSPS by using the par t together with an external multiplexer or demultiplexer. Programmable rounding is provided to suppor t output precisions from 8 bits to 16 bits.

Pin Description
NAME VCC GND CLK AIN0-15 BIN0-15 MODE0-1 INT/EXT SYNC TYPE I I I I I I +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 conver t Local Oscillators. In the straight decimate modes, this input can be use to synchronize the input sample stream with a par ticular 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 impar ted on the data stream in the Down Conver t and Decimate Mode and in the Quadrature to Real Conver t 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 conver t the two's complement output to offset binary (unsigned). When asser ted 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. DESCRIPTION
