3 / 121 page  PCM9211 www.ti.com SBAS495 – JUNE 2010 RECOMMENDED OPERATING CONDITIONS (continued) Over operating free-air temperature range (unless otherwise noted). MIN NOM MAX UNIT Analog input level VINL, VINR 3 VPP Digital output load capacitance Except SCKO 20 pF Digital output load capacitance SCKO 10 pF MODE pin capacitance 10 pF Operating free-air temperature –40 +25 +85 °C ELECTRICAL CHARACTERISTICS: GENERAL All specifications at TA = +25°C, VCC = VDD = VDDRX = 3.3 V, and VCCAD = 5 V, unless otherwise noted. PCM9211 PARAMETER TEST CONDITIONS(1) MIN TYP MAX UNIT DIGITAL INPUT/OUTPUT DATA FORMAT Audio data interface format I2S, Left-Justified, Right-Justified Audio data word length 16, 24 Bits Audio data format MSB first, twos complement Sampling frequency, DIR 7 216 kHz Sampling frequency, DIT 7 216 kHz fS Sampling frequency, Routing 7 216 kHz Sampling frequency, ADC 16 96 kHz INPUT LOGIC VIH (2) (3) 2.0 5.5 VDC Input logic level VIL (2) (3) 0.8 VDC VIH (4) 0.7 VCC VCC VDC Input logic level (XTI pin) VIL (4) 0.3 VCC VDC VIH (5) 0.7 VDDRX VDDRX VDC Input logic level (RXIN0/1 pins) VIL (5) 0.3 VDDRX VDC IIH (2) (4) VIN = VDD or VCC ±10 mA Input logic current IIL (2) (4) VIN = 0 V ±10 mA IIH (3) VIN = VDD 65 100 mA Input logic current (RST pin) IIL (3) VIN = 0 V ±10 mA IIH (5) VIN = VDDRX 165 300 mA Input logic current (RXIN0/1 pins) IIL (5) VIN = 0 V –165 –300 mA OUTPUT LOGIC VOH (6) IOUT = –4 mA 2.8 VDC Output logic level VOL (6) IOUT = 4 mA 0.5 VDC VOH (7) IOUT = –4 mA 0.85 VCC VDC Output logic level VOL (7) IOUT = 4 mA 0.15 VCC VDC (1) PLL lock-up time varies with ERROR release wait time setting (Register 23h/ERRWT). Therefore, lock-up time in this table shows the value at ERRWT = 11 as the shortest time setting. (2) Pins: MPIO_A0-A3, MPIO_B0-B3, MPIOC0-C3, RXIN2-RXIN7, MC/SCL, MDI/SDA, MDO/ADR0, MS/ADR1 (3) Pin: RST (4) Pin: XTI (5) Pins: RXIN0, RXIN1. Input impedance of RXIN0 and RXIN1 is 20 k Ω (typical). COAX amplifiers are powered on by Register 34h/RX0DIS and RX1DIS = 0. At power down by Register 34h/RX0DIS and RX1DIS= 1 (default), RXIN0 and RXIN1 are internally tied high. (6) Pins: MPIO_A0-A3, MPIO_B0-B3, MPIO_C0-C3, SCKO, BCK, LRCK, DOUT, MPO0-1, ERROR/INT0, NPCM/INT1. (7) Pin: XTO.
