Halfband Filter

Features

The HSP43216 Halfband Filter addresses a wide variety of

applications by combining f /4 (f = 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

• Sample Rates to 52 MSPS

• Architected to Support Sample Rates to 104 MSPS Using

External Multiplexer

• Four Modes of Operation:

- Interpolate by 2 Filtering

signal; interpolate by 2 ﬁltering of a real input signal; f /4

- Decimate by 2 Filtering

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

- Quadrature to Real Signal Conversion

- f /4 Quadrature Down Conversion Followed by

Decimate by 2 Filtering

followed by f /4 quadrature up conversion to produce a real

valued output.

• 16-Bit Inputs and Outputs

• 67-Tap Halfband FIR Filter with 20-Bit Coefﬁcients

• Two’s Complement or Offset Binary Outputs

• Programmable Rounding on Outputs

• 1.24:1 Filter Shape Factor

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 to 0.2f with

stopband attenuation of greater than 90dB from 0.3f to

Nyquist. At 0.25f the ﬁlter provides 6dB of attenuation.

• >90dB Stopband 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.

• <0.0003dB Passband Ripple

• Saturation Logic on Output

Applications

• Digital Down Conversion

• D/A and A/D pre/post Filtering

Ordering Information

• Tuning Bandwidth Expansion for HSP45116 and

HSP45106
