The HSP43168JC-33 is a dual finite impulse response (FIR) filter manufactured by Intersil. It integrates two independent 8-tap FIR filters that can be configured as a single 16-tap unit. The device supports programmable decimation ratios from 1 to 16 and includes on-board storage for 32 sets of coefficients. It utilizes a standard microprocessor interface for control and data transfer, operating within a commercial temperature range.
The HSP43168JC-33 belongs to the HSP43168 series of dual FIR filters produced by Intersil Corporation. This component is part of a family designed for high-speed digital signal processing applications requiring flexible filter configurations and internal coefficient management capabilities.
Verify pin compatibility and electrical specifications against potential substitutes. Ensure the replacement device supports the required decimation ratio and coefficient storage capacity. Confirm that the alternative component meets the same package and thermal requirements.
