10 / 19 page TC9470FN 2002-02-27 10 6. DA Conversion Circuit The IC incorporates a second-order Σ-∆ modulation DA converter for two channels (simultaneous output type). The internal structure of this is shown in Figure 9. The Σ-∆ modulation clock has been designed to operate at 192 fs (when 384 fs). The noise shaping characteristics are shown in Figure 10. 7. Data Output Circuit The output circuit is equipped with a third-order analog low-pass filter. This enables direct analog signals to be acquired from the IC’s RO (pin 5) and LO (pin 9) output pins. + + + 2 Q Z −1 Z −1 X (Z) Y (Z) Data − − Output data (bit-stream 1-bit DA conversion data) Limiter Second-order Σ-∆ converter: Y (Z) = X (Z) + (1 − Z −1)2 Q (Z) Figure 9 Σ-∆ Modulation DA Converter Frequency (Hz) 0 500 k 1 M 10dB Figure 10 Noise Shaping Characteristics PDM signals RO (LO) VR Figure 11 Analog Filter Circuit |
