HSP43216VC-52

The shape factor of the frequency response of the HSP43216's halfband filter is 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.

The HSP43216 Halfband Filter can be configured to operate in four modes: 1. Decimate by 2 filtering of a real input signal 2. Interpolate by 2 filtering of a real input signal 3. fS/4 quadrature down conversion of a real input signal followed by decimate-by-2 filtering to produce a complex analytic signal 4. Interpolate-by-2 filtering of a complex analytic signal followed by fS/4 quadrature up conversion to produce a real valued output.

The HSP43216 can process data streams with word widths up to 16 bits and data rates up to 52 MSPS. The processing throughput of the part can be easily doubled to rates of up to 104 MSPS by using the part together with an external multiplexer or demultiplexer.
