HSP45106JC-25Z

Programmable Timers And Oscillators Overview

The HSP45106JC-25Z is a 16-bit Numerically Controlled Oscillator (NCO) manufactured by Renesas Electronics Corporation, originally developed by Intersil. It operates at a maximum clock frequency of 25.6MHz and provides simultaneous 16-bit sine and cosine quadrature outputs. The device features a 32-bit center and offset frequency control register for precise tuning resolution better than 0.008Hz. It includes a 16-bit phase control register and supports up to 8-level PSK modulation via discrete inputs. The component utilizes an 84-lead PLCC package with RoHS compliance.
