HSP45102SC-40Z

DATASHEET HSP45102 FN2810 Rev 9.00 Apr 25, 2007 12-Bit Numerically Controlled Oscillator The Intersil HSP45102 is 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 frequency to be generated is selected from two frequency control words. A single control pin selects which word is used to determine the output frequency. Switching from one frequency to another occurs in one clock cycle, with a 6 clock pipeline delay from the time that the new control word is loaded until t4-he new frequency appears on the output. Two pins, P0-1, are provided for phase modulation. They are encoded and added to the top two bits of the phase accumulator to offset the phase in 90° increments. The 13-bit output of the Phase Offset Adder is mapped to the sine wave amplitude via the Sine ROM. The output data format is offset binary to simplify interfacing to D/A converters. Spurious frequency components in the output sinusoid are less than -69dBc. The NCO12 has applications as a Direct Digital Synthesizer and modulator in low cost digital radios, satellite terminals, and function generators. Features • 33MHz, 40MHz Versions • 32-Bit Frequency Control • BFSK, QPSK Modulation • Serial Frequency Load • 12-Bit Sine Output • Offset Binary Output Format • 0.009Hz Tuning Resolution at 40MHz • Spurious Frequency Components 1.5V and VOL < 1.5V. 6. If TXFR is active, care must be taken to not violate setup and hold times as data from the shift registers may not have settled before CLK occurs. 7. Controlled via design or process parameters and not directly tested. Characterized upon initial design and after major process and/or design changes.
