5 / 38 page PCM4204 SBAS327A − JUNE 2004 − REVISED SEPTEMBER 2004 www.ti.com 5 ELECTRICAL CHARACTERISTICS (continued) Unless otherwise noted, all characteristics specified with TA = +25°C, VCC = +5V, VDD = +3.3V, system clock (SCKI) is 512fS for Single Rate Sampling, 256fS for Dual Rate Sampling, or 128fS for Quad Rate Sampling. The device is operated in Master mode for all dynamic performance measurements. PCM4204 PARAMETER UNIT MAX TYP MIN TEST CONDITIONS DIGITAL DECIMATION FILTER (continued) Quad Rate Sampling Mode Passband Edge −0.005dB 0.375fS Hz −3dB 0.490fS Hz Passband Ripple ±0.005 dB Stop Band Edge 0.770fS Hz Stop Band Attenuation −135 dB Group Delay 9.5/fS sec DIGITAL HIGH PASS FILTER Frequency Response (−3dB) fS/48000 Hz POWER SUPPLY Voltage Range VCC1, VCC2 +4.75 +5.0 +5.25 VDC VDD1, VDD2, VDD3 +3.0 +3.3 +3.6 VDC Power Down Supply Current VCC = +5V, VDD = +3.3V, RST = Low ICC1 + ICC2 10 mA IDD1 + IDD2 + IDD3 2 mA Quiescent Current ICC1 + ICC2 VCC = +5.0V fS = 48kHz(4) 108 130 mA fS = 96kHz 108 130 mA fS = 192kHz 108 130 mA IDD1 + IDD2 + IDD3 VDD = +3.3V fS = 48kHz(4) 18 23 mA fS = 96kHz 30 44 mA fS = 192kHz 23 26 mA Total Power Dissipation VCC = +5V, VDD = +3.3V fS = 48kHz(4) 600 726 mW fS = 96kHz 640 795 mW fS = 192kHz 615 736 mW (1) Applies to the FMT0, FMT1, FMT2, S/M, FS0, FS1, FS2, HPFD, BCK, LRCK, SUB, DSDCLK, DSD1, DSD2, DSD3, DSD4, and SCKI pins. (2) Applies to the TEST and RST pins. (3) Typical performance is measured using an Audio Precision System Two Cascade or Cascade Plus test system. The measurement bandwidth is limited using the Audio Precision 22Hz high-pass filter in combination with either a 20kHz low-pass filter for fS = 48kHz or a 40kHz low-pass filter for fS = 96kHz and 192kHz. All A-weighted measurements are performed using the A-weighting filter in combination with the band limiting filters already mentioned. The measurements are made with the RMS detector selected. (4) A 256fS system clock is used at final production test for fS = 48kHz measurements. (5) Typical DSD performance is measured using an Audio Precision System Two Cascade or Cascade Plus test system. The measurement bandwidth is limited using the Audio Precision 22Hz high-pass filter in combination with a 20kHz low-pass filter. All A-weighted measurements are performed using the A-weighting filter in combination with the band limiting filter already mentioned. The measurements are made with the RMS detector selected. The 1-bit DSD data is converted to 24-bit linear PCM data for measurement using a PCM4204 configured for DSD input mode. |
