HSP50016JC-5296

Overview

The HSP50016JC-5296 is a digital downconverter (DDC) from Intersil designed for cellular communications. It integrates a synthesizer, quadrature mixer, and lowpass filter on a single chip. The device accepts a sampled data stream up to 16 bits wide at a maximum input rate of 75 MSPS. It performs downconversion, narrowband filtering, and decimation to produce baseband signals. The internal synthesizer supports CW, frequency hopping, and linear FM chirp formats. Output data can be configured in fixed-point or single-precision floating-point formats.

Feature Summary

• Integrates a synthesizer, quadrature mixer, and lowpass filter for complete digital downconversion
• Supports multiple signal formats including CW, frequency hopping, and linear FM chirps
• Features high stopband attenuation exceeding 106dB with composite passband ripple under 0.04dB
• Accepts serial control commands compatible with standard microprocessor I/O ports

Applications

• AMPS cellular networks
• CDMA cellular networks
• GSM cellular networks
• TDMA cellular networks

Procurement Notes

Verify the exact suffix against official Intersil documentation to confirm pinout and electrical specifications. Ensure the package type matches the required PLCC-44 footprint. Confirm that the manufacturer source is authorized, as this component may be discontinued or superseded by newer Renesas Electronics products. Check for any specific ordering suffixes that might indicate temperature range or packaging variations.

Selection Notes

Select this component when a single-chip solution for digital downconversion is required for cellular applications. It is suitable for systems needing integrated synthesis and filtering without external mixers. Consider the 75 MSPS input limit and 16-bit data width constraints. Evaluate if the available output formats meet the downstream processing requirements. Verify compatibility with existing serial control interfaces.

Part Context

This part belongs to the HSP50016 series of digital downconverters manufactured by Intersil Corporation. The series includes variants such as the HSP50016GC-52 and HSP50016JC-75. These devices are classified under RF ICs and specifically target wireless communication standards. The manufacturer has since become part of Renesas Electronics Corporation.
