HSP43216
Halfband Filter
The HSP43216 Halfband Filter addresses a wide variety of
applications by combining f
S
/4 (f
S
= 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; f
S
/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 f
S
/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 0f
S
to 0.2f
S
with
stopband attenuation of greater than 90dB from 0.3f
S
to
Nyquist. At 0.25f
S
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 part is easily doubled to rates of up to 104
MSPS by using the part together with an external multiplexer
or demultiplexer. Programmable rounding is provided to
support output precisions from 8 bits to 16 bits.
