4 / 30 page  PCM4202-EP SGLS388 – JUNE 2007 www.ti.com ELECTRICAL CHARACTERISTICS (continued) All parameters are specified at TA = 25°C with VCC = 5 V, VDD = 3.3 V (unless otherwise noted), and a measurement bandwidth from 20 Hz to 20 kHz, unless otherwise noted. System clock frequency is equal to 256 fS for Single and Dual Rate sampling modes, and 128 fS for Quad Rate sampling mode. PCM4202 PARAMETER TEST CONDITIONS UNIT MIN TYP MAX DYNAMIC PERFORMANCE(3) fS = 48 kHz, Single Rate BW = 20 Hz to 20 kHz VIN = –0.5 dBFS, fIN = 1 kHz –105 –95 Total harmonic distortion + noise THD+N dB VIN = –0.5 dBFS, fIN = 1 kHz (–40°C –90 to 85 °C) VIN = –60 dBFS, fIN = 1 kHz, 112 118 A-Weighted Dynamic range dB VIN = –60 dBFS, fIN = 1 kHz, 108 A-Weighted ( –40°C to 85°C) Dynamic range, no weighting VIN = –60 dBFS, fIN = 1 kHz 116 dB Channel separation ( –40°C to 85°C) 100 120 dB fS = 96 kHz, Dual Rate BW = 20 Hz to 40 kHz Total harmonic distortion + noise THD+N VIN = –0.5 dBFS, fIN = 1 kHz –105 dB VIN = –60 dBFS, fIN = 1 kHz, Dynamic range 118 dB A-Weighted Dynamic range, no weighting VIN = –60 dBFS, fIN = 1 kHz 112 dB Channel separation 120 dB fS = 192 kHz, Quad Rate BW = 20 Hz to 40 kHz Total harmonic distortion + noise THD+N VIN = –0.5 dBFS, fIN = 1 kHz –103 dB Dynamic range VIN = 0 VRMS, A-Weighted 117 dB Dynamic range, no weighting VIN = 0 VRMS 108 dB Channel separation 120 dB DSD Output, 64 fS Rate DSDBCK = 2.8224 MHz Total harmonic distortion + noise THD+N VIN = –0.5 dBFS, fIN = 1 kHz –102 dB VIN = –60 dBFS, fIN = 1 kHz, Dynamic range 115 dB A-Weighted Channel separation 120 dB DSD Output, 128 fS Rate DSDBCK = 5.6448 MHz Total harmonic distortion + noise THD+N VIN = –0.5 dBFS, fIN = 1 kHz –105 dB VIN = –60 dBFS, fIN = 1 kHz, Dynamic range 118 dB A-Weighted Channel separation 120 dB DIGITAL DECIMATION FILTER Passband edge Single and Dual Rate 0.453 fS Hz Passband ripple Single and Dual Rate �0.005 dB Passband edge Single and Dual Rate 0.547 fS Hz Stop band attenuation Single and Dual Rate –100 dB Group delay Single and Dual Rate 37/fS sec Passband edge ( –0.005 dB) Quad Rate 0.375 fS Hz –3 dB cutoff frequency Quad Rate 0.490 fS Hz Passband ripple Quad Rate ±0.005 dB Passband edge Quad Rate 0.770 fS Hz Stop band attenuation Quad Rate –135 dB (3) Dynamic performance parameters are measured using an Audio Precision System Two Cascade or Cascade Plus test system. The measurement bandwidth is limited by using the Audio Precision 22 Hz high-pass filter in combination with the Audio Precision 20 kHz, fS/2, or a user-defined 40 kHz low-pass filter. All A-weighted measurements are performed using the Audio Precision A-weighting filter in combination with the previously mentioned filters. 4 Submit Documentation Feedback Copyright © 2007, Texas Instruments Incorporated Product Folder Link(s): PCM4202-EP |
