PDSP16350/A0/AC中文資料ZARLINK數(shù)據(jù)手冊PDF規(guī)格書

The PDSP16350 provides an integrated solution to the need for very accurate, digitised, sine and cosine waveforms. Both these waveforms are produced simultaneously, with 16 bit amplitude accuracy, and are synthesised using a 34 bit phase accumulator. The more significant bits of this provide 16 bits of phase accuracy for the sine and cosine look up tables.

FEATURES

■ Direct Digital Synthesiser producing simultaneous sine and cosine values

■ 16 bit phase and amplitude accuracy, giving spur levels down to - 90 dB

■ Synthesised outputs from DC to 10 MHz with accuracies better than 0.001 Hz

■ Amplitude and Phase modulation modes

■ 84 pin PGA or 132 pin QFP

APPLICATIONS

■ Numerically controlled oscillator (NCO)

■ Quadrature signal generator

■ FM, PM, or AM signal modulator

■ Sweep Oscillator

■ High density signal constellation applications with simultaneous amplitude and phase modulation

■ VHF reference for UHF generators

■ Signal demodulator
