The Intersil HSP45102 is a Numerically Controlled Oscillator (NCO12) with 32-bit frequency resolution and 12-bit output. With over 69dB of spurious free dynamic range and worst case frequency resolution of 0.009Hz, the NCO12 provides significant accuracy for frequency synthesis solutions at a competitive price.
The HSP45102 is a 12‑bit Numerically Controlled Oscillator (NCO) offering 32‑bit frequency control and fine tuning resolution for frequency synthesis applications. It provides a 12‑bit sine output in offset‑binary format and supports phase modulation via two dedicated pins.
Key features include 0.009 Hz tuning resolution at 40 MHz, spurious frequency components better than –69 dBc, and operation over a wide temperature range. The device is supplied in a 28‑lead SOIC package and conforms to RoHS‑compliant, Pb‑free processes.
