www.ti.com ELECTRICAL CHARACTERISTICS PCM3000 PCM3001 SBAS055A OCTOBER 2000 REVISED OCTOBER 2004 This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

Audio Data Input/Output Timing The system clock for the PCM3000/3001 must be either 256 f S 384 f S or 512 f S where f S is the audio sampling frequency. The system clock can be either a crystal oscillator placed between XTI (pin 20) and XTO (pin 21), or an external clock input. If an external clock is used, the clock is provided to either XTI or CLKIO (pin 22), and XTO is open. The PCM3000/3001 has an XTI clock detection circuit which senses if an XTI clock is operating. When the external clock is delivered to XTI, CLKIO is a buffered output of XTI. When XTI is connected to ground, the external clock must be tied to CLKIO. For best performance, the external-clock-input-2 circuit in Figure is recommended. The PCM3000/3001 also has a system-clock detection circuit which automatically senses if the system clock is operating at 256 f S 384 f S or 512 f S When a 384-f S or 512-f S system clock is used, the clock is divided into 256 f S automatically.

DAC Output and ADC Output for Reset and Power Down The PCM3000/3001 includes a reset input, RSTB (pin 28). As shown in Figure the external reset signal must drive RSTB low for a minimum of nanoseconds while the system clock is active in order to initiate the reset sequence. Initialization starts on the rising edge of RSTB, and requires 1024 system clock cycles for completion. Figure shows the state of the DAC and ADC outputs during and after the reset sequence. Figure 27. External Forced-Reset Timing The PCM3000/3001 operates with LRCIN synchronized to the system clock. The codec does not require any specific phase relationship between LRCIN and the system clock, but there must be synchronization of LRCIN and the system clock. If the synchronization between the system clock and LRCIN changes more than bit clocks (BCKIN) during one sample (LRCIN) period because of phase jitter on LRCIN, internal operation of the DAC stops within 1/f S and the analog output is forced to bipolar zero CC 2/2) until the system clock is resynchronized to LRCIN. Internal operation of the ADC also stops within 1/f S and the digital output codes are set to bipolar zero until resynchronization occurs. If LRCIN is synchronized within or fewer bit clocks to the system clock, operation remains normal. Figure illustrates the effects on the output when synchronization is lost. Before the outputs are forced to bipolar zero <1/f S seconds), the outputs are not defined and some noise may occur. During the transitions between normal data and undefined states, the output has discontinuities, which cause output noise.

The block diagram in this data sheet illustrates the architecture of the ADC section. Figure shows the single-to-differential converter, and Figure illustrates the architecture of the 5th-order delta-sigma modulator and transfer functions. An internal high-precision reference with two external capacitors provides all reference voltages required by the ADC, which defines the full scale range for the converter. The internal single-to-differential voltage converter saves the space and extra parts needed for external circuitry which is required by many delta-sigma converters. The internal full-differential signal processing architecture provides a wide dynamic range and excellent power supply rejection performance. The input signal is sampled at a oversampling rate, eliminating the need for a sample-and-hold circuit, and simplifying antialias filtering requirements. The 5th-order delta-sigma noise shaper consists of five integrators which use a switched-capacitor topology, a comparator, and a feedback loop consisting of a one-bit DAC. The delta-sigma modulator shapes the quantization noise, shifting it out of the audio band in the frequency domain. The high order of the modulator enables it to randomize the modulator outputs, reducing idle tone levels. The 64-f S 1-bit data stream from the modulator is converted to 1-f S 18-bit data words by the decimation filter, which also acts as a low-pass filter to remove the shaped quantization noise. The dc components are removed by a high-pass filter function contained within the decimation filter. Figure 31. Simplified Fifth-Order Delta-Sigma Modulator The delta-sigma DAC section of the PCM3000/3001 is based on a 5-level amplitude quantizer and a 3rd-order noise shaper. This section converts the oversampled input data to a 5-level delta-sigma format. A block diagram of the 5-level delta-sigma modulator is shown in Figure This 5-level delta-sigma modulator has the advantage of improved stability and reduced clock-jitter sensitivity over the typical one-bit (2-level) delta-sigma modulator. The combined oversampling rate of the delta-sigma modulator and the internal interpolation filter is f S for a 256-f S system clock. The theoretical quantization noise performance of the 5-level delta-sigma modulator is shown in Figure

Example: 2.2 µ F sets the cutoff frequency to 4.8 Hz, with a 66-ms time constant. Figure 34. Typical Connection Diagram for PCM3000/3001 The digital and analog power-supply lines to the PCM3000/3001 should be bypassed to the corresponding ground pins with both 0.1- µ F ceramic and 10- µ F tantalum capacitors as close to the device pins as possible to maximize the performance of the ADC and DAC. Although the PCM3000/3001 has three power supply lines to optimize dynamic performance, the use of one common power supply is generally recommended to avoid unexpected latch-up or pop noise due to power-supply sequencing problems. If separate power supplies are used, back-to-back diodes between the two power sources near the device are recommended to avoid latch-up problems.

www.ti.com GROUNDING VOLTAGE INPUTS V REF INPUTS C IN P AND C IN N INPUTS VCOM INPUT SYSTEM CLOCK RSTB CONTROL PCM3000 PCM3001 SBAS055A OCTOBER 2000 REVISED OCTOBER 2004 APPLICATION INFORMATION (continued) In order to optimize dynamic performance of the PCM3000/3001, the analog and digital grounds are not internally connected. PCM3000/3001 performance is optimized with a single ground plane for all returns. It is recommended to tie all PCM3000/3001 ground pins to the analog ground plane using low-impedance connections. The PCM3000/3001 should reside entirely over this plane to avoid coupling high-frequency digital switching noise into the analog ground plane. A tantalum or aluminum electrolytic capacitor, between 2.2 µ F and µ is recommended as an ac-coupling capacitor at the inputs. Combined with the 15-k Ω characteristic input impedance, a 2.2- µ F coupling capacitor establishes a 4.8-Hz cutoff frequency for blocking dc. The input voltage range can be increased by adding a series resistor on the analog input line. This series resistor, when combined with the 15-k Ω input impedance, creates a voltage divider and enables larger input ranges. A 4.7- µ F to 10- µ F tantalum capacitor is recommended between V REF V REF and AGND1 to ensure low source impedance for the ADC references. These capacitors should be located as close as possible to the reference pins to reduce dynamic errors on the ADC reference. A 470-pF to 1000-pF film or NPO ceramic capacitor is recommended between C IN PL and C IN NL, and also between C IN PR and C IN NR to create an antialias filter that has a 170-kHz to 80-kHz cutoff frequency. These capacitors should be located as close as possible to the C IN P and C IN N pins to avoid introducing undesirable noise or dynamic errors into the delta-sigma modulator. A 4.7- µ F to 10- µ F tantalum capacitor is recommended between VCOM and AGND2 to ensure low source impedance of the DAC output common. This capacitor should located as close as possible to the VCOM pin to reduce dynamic errors on the DAC common. The quality of the system clock can influence the dynamic performance of both the ADC and DAC in the PCM3000/3001. The duty cycle, jitter, and threshold voltage at the system clock input pin should be carefully managed. When power is supplied to the part, the system clock, bit clock (BCKIN), and word clock (LCRIN) must also be supplied simultaneously. Failure to supply the audio clocks results in a power dissipation increase of up to three times normal dissipation and may degrade long-term reliability if the maximum power dissipation limit is exceeded. If capacitors greater than 4.7 µ F are used on V REF and VCOM, an external reset control with delay time corresponding to the V REF VCOM response is required.
