HSP45106JC-33Z

Programmable Timers And Oscillators Overview

The HSP45106JC-33Z is a 16-bit quadrature Numerically Controlled Oscillator (NCO) manufactured by Renesas Electronics Corporation. It operates with a maximum clock frequency of 33MHz and provides simultaneous 16-bit sine and cosine outputs. The device features a 32-bit center and offset frequency control register, enabling tuning resolution better than 0.008Hz at the maximum clock rate. It includes a 16-bit phase control register for precise phase adjustments and supports up to 8-level PSK modulation via a discrete three-pin interface. The spurious-free dynamic range exceeds 90dBc. The component is housed in an 84-lead PLCC package and functions within a temperature range of 0°C to +70°C.
