Four-Channel Programmable Digital

Downconverter

The HSP50216 Quad Programmable Digital Downconverter

(QPDC) is designed for high dynamic range applications

such as cellular basestations where multiple channel

processing is required in a small physical space. The QPDC

combines into a single package, a set of four channels which

include: digital mixers, a quadrature carrier NCO, digital

filters, a resampling filter, a Cartesian-to-polar coordinate

converter and an AGC loop.

The HSP50216 accepts four channels of 16-bit real digitized IF

samples which are mixed with local quadrature sinusoids. Each

channel carrier NCO frequency is set independently by the

microprocessor. The output of the mixers are filtered with a CIC

and FIR filters, with a variety of decimation options. Gain

adjustment is provided on the filtered signal. The digital AGC

provides a gain adjust range of up to 96dB with programmable

thresholds and slew rates. A cartesian to polar coordinate

converter provides magnitude and phase outputs. A frequency

discriminator provides a frequency output via the FIR filter.

Selectable outputs include I samples, Q samples, Magnitude,

Phase, Frequency and AGC gain. The output resolution is

selectable from 4-bit fixed point to 32-bit floating point.

The maximum output bandwidth achievable using a single

channel is at least 1MHz.

Ordering Information

NOTE: These Intersil Pb-free WLCSP and BGA packaged products

products employ special Pb-free material sets; molding compounds/die

attach materials and SnAgCu - e1 solder ball terminals, which are RoHS

compliant and compatible with both SnPb and Pb-free soldering

operations. Intersil Pb-free WLCSP and BGA packaged products are

MSL classified at Pb-free peak reflow temperatures that meet or exceed

the Pb-free requirements of IPC/JEDEC J STD-020.
