HSP43216JC-52Z

Overview

The HSP43216JC-52Z is a halfband filter component manufactured by Renesas Electronics Corporation (formerly Intersil). It integrates fS/4 quadrature up/down conversion circuitry with a fixed coefficient halfband filter processor. The device supports sample rates up to 52MSPS, which can be doubled to 104MSPS using an external multiplexer. It processes data streams with word widths up to 16-bits and features programmable rounding for output precisions ranging from 8-bits to 16-bits. The filter provides a shape factor of 1.24:1 with greater than 90dB stopband attenuation and less than 0.0003dB passband ripple. It operates within a temperature range of 0°C to +70°C and is housed in an 84-lead PLCC package.

Feature Summary

• Integrates fS/4 quadrature processing with a 67-tap halfband FIR filter
• Supports four operational modes including decimate, interpolate, and quadrature conversion
• Features programmable output rounding from 8-bit to 16-bit precision
• Provides saturation logic on outputs to handle numerical growth

Applications

• Digital down conversion systems
• Pre/post filtering for D/A and A/D converters
• Tuning bandwidth expansion for companion HSP45116 and HSP45106 devices

Procurement Notes

Verify the manufacturer origin as this part was originally produced by Intersil before its acquisition by Renesas. Confirm the specific suffix 'Z' indicates the Pb-free RoHS compliant version packaged in an 84-lead PLCC. Check current availability status as the datasheet explicitly marks this component as not recommended for new designs.

Selection Notes

Select this component for applications requiring fixed-coefficient halfband filtering with integrated quadrature conversion capabilities. Ensure the design accommodates the 0°C to +70°C operating temperature range. Consider the 16-bit input/output word width and verify if the internal or external multiplexing mode aligns with the system's clocking architecture.

Part Context

This component belongs to the HSP43216 series of halfband filters. The JC-52 variant specifically denotes the commercial temperature grade and 52MSPS speed class. The 'Z' suffix identifies the lead-free packaging option. It is part of a family designed for high-speed signal processing tasks involving spectral shifting and decimation/interpolation.

Replacement Considerations

The datasheet explicitly states that no recommended replacement is available for this discontinued product. Designers must evaluate existing stock or consider redesigning with newer components if long-term supply is required.
