HSP43168VC-33

Overview

The HSP43168VC-33 is a dual finite impulse response (FIR) filter manufactured by Renesas Electronics, formerly Intersil. It integrates two independent 8-tap FIR filters that can be configured as a single 16-tap filter. The device supports programmable decimation ratios from 1 to 16 and includes on-board storage for 32 sets of coefficients. It processes 10-bit data and coefficients, supporting complex filtering, quadrature operations, and 2-D convolution. The component operates within a commercial temperature range of 0°C to +70°C and utilizes a standard microprocessor interface.
