Initial System Settings 9.1 System Reset (XMODE) • The system operates correctly when XMODE is set to "H" after 3.0V or higher supply voltage is applied. When XMODE is set to "L" after power is turned on, the system is reset. • To set chip address, master/slave, or pins 44 to 47 I/O, 10kΩ pull-down or pull-up resistors must be connected to MOUT, AUDIO , CKST, and INT . • If none of MOUT, AUDIO , CKST, and INT are pulled down or pulled up, their pin state will get unstable when the settings are entered, resulting in wrong setting. Pull-up or pull-down resistors must be connected to these pins without fail.

By this setting, 4 kinds of chip addresses can be set at a maximum. • Chip addresses in the microcontroller interface are set with CAL and CAU provided as the first two bits on the LSB side. CAL corresponds to the lower chip address and CAU to the higher chip address. ____________ • Command writing is enabled by making the chip address settings with MOUT and AUDIO identical to the chip addresses sent from the microcontroller. • The chip address setting is required even when only one LC89058W-E is used in the system. If the chip address is not set, the chip address is undefined and the microcontroller cannot control the system. When the microcontroller is not used, a chip address-setting pin____________ is input open while XMODE is "L". Be sure to connect either a pull-down resistor or a pull-up resistor to MOUT and AUDIO.

For this setting, connects either a 10kΩ pull-down or a pull-up resistor to CKST. • Set to the master mode normally, when single LC89058W-E IC is used. When multiple LC89058W-Es are used, set one of them to the master mode and the others to the slave mode. • In the multi-channel synchronous transfer mode using multiple LC89058W-Es, connect RBCK and RLRCK (output) on the master side to RBCK and RLRCK (input) on the slave side. Also connect XMCK on the master side to XIN on the slave side. At this time, the polarity of RBCK and RLRCK, and the frequency of XIN and XMCK must be identical. • The master/slave function runs correctly with the multiple LC89058W-Es connected. • Be sure to connect either a pull-down resistor or a pull-up resistor to CKST. • Always supply the clock to RBCK and RLRCK when the slave function is set.

No.A1056-18/64 LC89058W-E 10 Description of Demodulation Function 10.1 Clocks 10.1.1 PLL (LPF) • The LC89058W-E incorporates a VCO (Voltage Controlled Oscillator) that can be stopped with PLLOPR and it synchronizes with sampling frequencies (fs) from 32kHz to 192kHz and with the data with transfer rate from 4MHz to 25MHz. PLL is locked at 512fs. • LPF is a pin for PLL loop filter. Connect the following resistance and capacitance shown in the figure. LPF R0 C0 C1 R0 : 220Ω C0 : 0.1μF C1 : 0.022μF Figure 10.1 Loop Filter Configuration 10.1.2 Oscillation amplifiers (XIN, XOUT, XMCK) • The LC89058W-E features a built-in oscillation amplifier. Connecting a quartz resonator, feedback resistor, and load capacitance to XIN and XOUT can configure an oscillation circuit. When connecting a quartz resonator, use one with a fundamental wave. Be aware that the load capacitance depends on the quartz resonator characteristics. • If the built-in oscillation amplifier is not used and oscillation module is used as the clock source instead, connect the output of an external clock supply source to XIN. At this time, it is not necessary to connect a feedback resistor between XIN and XOUT. • Always supply XIN with the 12.288MHz or 24.576MHz clock set with XINSEL. If supplying other frequencies to XIN, it is necessary to set that the result of change in sampling frequency fs of input data with FSERR is not reflected to an error flag. By this setting, the operation functions properly. Since it is not a recommended frequency, it cannot be used for input fs calculations. • The setting of XINSEL must be completed prior to S/PDIF input. • Supply XIN with clocks all the time to be used in the following applications. (1) Detection of presence or absence of S/PDIF input (2) Clock source while PLL is unlocked (3) Calculation of input data sampling frequency (4) Time definition when switching input data (5) External source of supply clock (clock for an AD converter, etc.) in XIN source mode. (6) Polling processing performed when setting the general-purpose I/O input function • The oscillation amplifier runs even when the PLL is locked. Therefore, data detection and calculation of input sampling frequency become possible while the PLL is locked. In that case, both the oscillation amplifier clock and the PLL clock signals coexist, and then user must pay attention and make sure sound quality is not adversely affected. • If adverse effects on the sound quality are recognized, it is possible to set with the AMPOPR [1:0] that the oscillation amplifier automatically stop operation while the PLL is locked. Therefore, setting of the AMPOPR [1:0] must be completed either prior to S/PDIF input or while PLL is unlocked. • The oscillation amplifier can be stopped if it is unnecessary. However, when the normal operation is resumed, it must wait for 10ms or longer until the resonator oscillation gets stable. • XMCK outputs the XIN clock. The XMCK output is set with XMSEL [1:0]. The XIN clock can be set to 1/1, 1/2, 1/4, or muted output. • If you use only the oscillation amplifier, input the quartz resonator to XIN and XOUT or an external clock to XIN, and fix the electric potential of digital data input pins of RX0 to RX6, or set with RISEL [2:0] that all the inputs are deselected. No.A1056-19/64 LC89058W-E 10.1.3 Switching between master clock and clock source • The RMCK, RBCK, and RLRCK (hereunder, R system), and the SBCK and SLRCK (hereunder, S system) clock sources can be selected between the following two master clocks. (1) PLL source (512fs) (2) XIN source (12.288MHz or 24.576MHz) • Clock source switching is to set with the R and S systems interlocked. This setting is carried out with OCKSEL. • The clock source is automatically switched to the PLL or XIN clock by locking/unlocking the PLL. The clock source can be switched to XIN with OCKSEL, regardless of the PLL status. Table 10.1: Relationship between Clock Source Switch Commands and Clock Sources when PLL Locked/Unlocked R System Clock Source S System Clock Source OCKSEL Locked Unlocked Locked Unlocked 0 PLL XIN PLL XIN 1 XIN XIN XIN XIN • The PLL status can be always monitored with RERR even after switching to the XIN source. Moreover, the processed information can be read with the microcontroller interface regardless of the PLL status. 10.1.4 Points to notice about switching clock source while PLL is locked • It is necessary to set the oscillation amplifier to the continuous operation mode at the same time with AMPOPR [1:0] to do the clock switch to the XIN source with OCKSEL when the oscillation amplifier has stopped in the state where the PLL is locked. The clock is not output when switching to the XIN clock source without executing this setting. • In the state where the PLL is locked, if the clock is switched to XIN source with OCKSEL while the oscillator amplifier is stopped, RERR is temporarily outputs an error (high level) indication. When switched to XIN source, the oscillator amplifier is switched to the operating state at the same time. RERR is temporality outputs an error (H level) indication when the oscillation amplifier switches from the stop condition to the continuous mode. Consequently the input fs calculation restarts. At this time, the previous fs calculation value is reset and compared with the newly calculated fs value. Then those two values are found not identical, that’s why the error is temporarily issued.

Subsequently, CKSTP is assumed to be 0. • In the lock-in stage, the CKST falls at the word clock generated from the XIN clock after PLL is locked following detection of input data, and rises at the same timing as RERR after a designated period. • In the unlock stage, the CKST falls at the same timing as RERR, PLL lock detection signal, and rises after word clocks generated from the XIN clock are counted for a designated period. • Change of the PLL lock status and timing of the clock change can be seen by detecting the rising and falling edges and pulses of CKST. • The clock is switched after the PLL lock condition is tested and identified. The timing of this clock switching is determined by setting the PTOXW [1:0]. The initial value is such that the clock is switched in 2.7ms after the falling edge of CKST. The value, however, assumes that the oscillation amplifier is set to permanent operation mode. If the oscillation amplifier is set to be stopped after PLL locking, the startup time before the oscillation amplifier stabilizes after PLL unlocking, is added. • A free-running clock is output from the clock output pin immediately after PLL unlocking.

Table 10.4: S/PDIF Reception Range (FSLIM [1:0]=00) PLL Output Clock Setting Input Data Reception Range 512fs 30kHz to 192kHz Note: (1) Reception range of RX1 is 32kHz to 96kHz. (2) PLL output clock is frequency-divided with PLLACC, PLLDIV and PRSEL [1:0] and is output from RMCK. • The fs reception range for input data can be limited within the set range of PLL output clocks stated above. This setting is carried out with FSLIM [1:0]. When this function is adopted, input data exceeding the set range is considered as an error, the clock source is automatically switched to the XIN source, and RDATA output data is subject to the RDTSEL setting. 10.2.2 S/PDIF I/O pins (RX0 to RX6, RXOUT1, RXOUT2) • S/PDIF input pins are 7 inputs at maximum. (1) RX1 is a coaxial-compatible input pin. When using RX1, connect RX0 and RX2 to GND. (2) RX0, RX2, RX3, RX4, RX5, and RX6 are TTL input level pins with 5V-tolerance voltage. (3) Make sure that the selected pins are not input-open. For points to notice on RX1, see the following subsection. (4) The unselected pins are pulled down with their internal resistors. • The demodulation input and S/PDIF through-output pins RXOUT1 and RXOUT2 data can be selected independently. (1) The demodulation data is selected with RISEL[2:0]. (2) The RXOUT1 output data is selected with ROSEL[2:0]. (3) The RXOUT2 output data is selected with RXSEL[2:0]. • It is possible to deselect all of RX0 to RX6 with RISEL[2:0] (RISEL[2:0]=111). • RXOUT1 and RXOUT2 can be muted with RXOSEL[2:0] and RXSEL[2:0], respectively. Muting is recommended to reduce jitter when RXOUT1 and RXOUT2 are not used. • The data input state can be monitored with the RXMON setting. The status of each data input pin is stored in CCB address 0xEA and output registers DO0 to DO7. Moreover, the latest information can be read with the microcontroller by setting the interrupt processing command INDET. For details, see Chapter 12, Microcontroller Interface. • The frequencies of input data that can be monitored with this setting is from 32kHz to 192kHz. The data detection function applies to IEC60958 compatible S/PDIF data. The frequency of the clock supplied to XIN when RXMON is set is limited to 24.576MHz. LC89058W-E does not run at any clock frequency other than 24.576MHz. Moreover, since this function uses the XIN clock, the oscillation amplifier must be set in the continuous operation mode when RXMON is set. • When the data input monitoring is specified, the input pins, except RX1pin and those which are selected for demodulation, are pulled down. This is to preclude input-open when detecting no connection input pins. For the peripheral circuit of the RX1 pin, see the following page. No.A1056-27/64 LC89058W-E 10.2.3 S/PDIF input circuits (RX0 to RX6) • RX0, RX2, RX3, RX4, RX5, and RX6 can be received the data of 32kHz to 192kHz. • RX1 can be received up to 96kHz data. • If RX1 with a built-in amplifier is used as a coaxial input pin, malfunction may occur due to the influence from the adjacent RX0 and RX2 input pins. To avoid the influences from those pins, fix RX0 and RX2 to "L". In addition, the pull-down resistor is inserted after the coupling capacitor for the noise measures, when the signal is not connected with RX1 is selected. • When RX1 is selected and the input signal to RX1 is always fixed to either "H" or "L" (Toslink etc), RX0 and RX2 processes are not required. • RX0, RX2, RX3, RX4, RX5, and RX6 are TTL input level compatible S/PDIF input pins with 5V-tolerance voltage.

This output is automatically switched according to the PLL locked/unlocked status. For details, see the timing charts below. • When SDIN input data is selected, switch to a clock source synchronized to the SDIN data. • With the RDTSTA setting, the SDIN input data is output to RDATA regardless of the locked/unlocked status of the PLL. • With the RDTMUT setting, the RDATA output data can be also muted forcibly. • Even when the clock source is set to XIN with OCKSEL and RCKSEL, the PLL continues operating as long as the PLL is not stopped with PLLOPR. At this time, the PLL status is continuously output from RERR unless error output is forcibly set with RESTA. Moreover, the processed information can be read with the microcontroller interface regardless of the PLL status.

Therefore, the value remains unchanged until the PLL becomes unlocked. • If the oscillation amplifier is in a continuous operation mode, calculation is repeated constantly. Even if sampling changes within the PLL capture range for input data whose channel status sampling information does not change, the calculation results that follow the input data can be read. • The calculation results can be readout via MOUT pin or with the microcontroller interface. Since the MOUT pin is also used to generate the emphasis information, set the contents of the MOUT pin output by MOSEL. The fs calculation output to the MOUT pin is limited. The FSSEL[1:0] sets the contents of the MOUT pin output.

Since the PLL status can be output at all times, the PLL status can be always monitored, even when the clock source is XIN. 10.4.2 PLL lock error • The PLL gets unlocked for input data that lost bi-phase modulation regularity, or input data for which preambles B, M, and W cannot be detected. However, even if preambles B, M, and W are detected if the timing does not conform to the IEC60958, the PLL get unlocked and processed. For example, period of preamble B is not every192 frames. • RERR turns to “H” when the PLL lock error occurs and returns to “L” when the data demodulation returns normal and “H” is held for somewhere between 3ms to 144ms. This holding time is determined with the ERWT[1:0] setting. • The rising and falling edges of RERR are synchronized with RLRCK. 10.4.3 Input data parity error • Odd number of errors among parity bits in input data and input parity errors are detected. • If an input parity error occurs 9 or more times in succession, RERR turns to "H" indicating that the PLL is locked, and after holding "H" for somewhere between 3ms and 144ms, it returns to "L". • The error flag output format can be selected with REDER, when an input parity error is output less than 8 times in succession. 10.4.4 Other errors • Even if RERR turns to "L", the channel status bits of 24 to 27 (sampling frequency) are always fetched and the data of the previous block is compared with the current data. Moreover, the input data sampling frequency is calculated from the fs clock extracted from the input data, and the fs calculated value is compared in a same way as described above. If any difference is detected in these data, RERR is instantly made "H" and the same processing as for PLL lock errors is carried out. • The PLL causes a lock error when the fs changes as described above. However, in order to support sources with a variable fs (for example a CD player with a variable pitch function), it is possible to set with FSERR not to output an error flag unless fs changes exceeding the PLL capture range. In the FSERR setting, when the PLL is locked, RERR is turned to “L” without reflecting the fs calculation result to the error flag concerning input data within reception range by FSLIM [1:0]. Moreover, the data comparison at the channel status bits of 24 to 27 as described above is not performed. • If a setting which regard non-PCM data input as an error is made with RESEL, RERR turns to “H” when non-PCM data input is detected. At this time, the PLL locked status and various output clocks are subject to the input data, but the output data is muted. No.A1056-33/64 LC89058W-E 10.4.5 Data processing upon occurrence of errors (lock error, parity error) • The data processing upon occurrence of an error is described below. If 8 or fewer input parity errors occur in succession and transfer data is PCM audio data, the data is replaced by the one saved each in L-ch and R-ch in the previous frame. However, if the transfer data is non-PCM data, the error data is output as it is. • Non-PCM data is the data of when bit 1 (audio sample word) of the channel status turns to "H" based on the data detected prior to the occurrence of the input parity error. • Output data is muted when a PLL lock error occurs or a parity error occurs 9 or more times in succession. • As for the channel status output, the data of the previous block is held in 1-bit units when a parity error occur 8 or fewer times in succession.

If bit 1 is PCM data, detection flag is not output. • The DTS-CD/LD sync signal detection is done based on the sync pattern and the base frequency. The sync pattern is checked every 4096th frame, and the detection status is held until the sync pattern is no longer verified. •The IEC61937 and DTS-CD/LD detection flags can be readout with the microcontroller interface in addition to output ____________ to the AUDIO pin by AOSEL. When the UNPCM non-PCM signal output setting is selected through the INT output contents setting, an interrupt signal is output from INT detecting an IEC61937 or DTS-CD/LD sync signal. Reading output register from this information can see details of Non-PCM signal. This information is used to read out the output register and identify the details of the non-PCM signal • The detection flags are cleared when fs is changed or when a PLL lock error or data error occurs.

(5) INT turns “H” and the data is held in the register immediately when address 0xEA is readout. (6) The read data from the PO[3:0] is transferred to the microcontroller. At the same time, the data in the register is cleared. (7) The contents of the register are updated if INT turns to “L” before P0[3:0] is readout. 11.3.1.2 GPIO=0 (not using INT ) (1) The data inputs to the GPIO0, GPIO1, GPIO2, and GPIO3 pins are taken in when the CCB address 0xEB is set.

However, since switching between clock and data output can be set independently; it is recommended to select mute or SDIN data for the output data when XIN source is switched. • If the oscillation amplifier is set to stop automatically when the PLL gets locked, XIN source switching from the PLL locked status disables the clock output. Be sure to set the oscillation amplifier to the continuous operation mode when switching the clock source to the XIN source.
