Ordering number : ENA1056A CMOS IC LC89058W-E Digital Audio Interface Receiver 1. Overview The LC89058W-E is a digital audio interface receiver IC that demodulates signals according to a data transfer format between digital audio devices via the IEC60958/61937 and JEITA CPR-1205. It supports demodulation sampling frequencies of up to 192kHz. The LC89058W-E can easily replace the existing LC89057W-VF4A-E. The LC89058W-E incorporates a number of features for its low cost and is optimal for receiving digital data for AV amplifiers and receivers. 2. Features 2.1 Clock Built-in PLL false lock prevention circuit to provide accurate lock. Includes built-in oscillation amplifier and frequency divider for quartz resonator. Output clock: 512fs, 256fs, 128fs, 64fs, 32fs, 16fs, 2fs, fs, 1/2fs, and 1/4fs. Possible to set the oscillation amplifier (external input) clock output regardless of the PLL status. Generates transition period signal for switching between the PLL clock and oscillation amplifier (external input) clock. Allows the user to set the PLL clock output frequency for each sampling frequency band of input data. 2.2 Data Can receive S/PDIF and serial data at sampling frequencies of 32kHz to 192kHz. Equipped with a total of 7 digital data input pins: 1 input pin with an amplifier and 6 input pins with 5V tolerable TTL level signal. Can generate data to be demodulated and through output data separately from a maximum of 7 kinds of S/PDIFs. Equipped an S/PDIF input data detection function. Possible to monitor the data input status of 32kHz to 192kHz with microcontroller. Continued on next page.

Equipped with a serial data input pin. Possible to switch with demodulation output automatically according to the state of the PLL circuit. The fs reception range of S/PDIF interface can be limited. LC89058W-E can be set to a no-signal input state if the reception range is exceeded. 2 Supports I S data output that facilitates interfacing with DSP. 2.3 Other Supports Multi-channel transfer and reception, using master/slave function. Equipped with a 4bits general-purpose I/O pins. They can be used for interface with peripheral ICs. The general-purpose I/O pins can also serve as selector inputs. Possible to switch with HDMI and XM-radio signals. Generates a DTS-CD/LD detection flag on detection of a DTS synchronization signal. Outputs interrupt signal for microcontroller (interrupt source can be selected). Calculates sampling frequency of input signal and outputs it from the terminal or microcontroller interface. Outputs IEC61937 burst preamble Pc from microcontroller interface. Outputs IEC60958 bit 1 of channel status (non-PCM data delimiter bit). Outputs emphasis information of channel status. Can use up to four LC89058W-Es at the same time by setting the 2-bit chip address. Runs on a single 3.3V power supply (S/PDIF input and microcontroller interface support 5V TTL interface.)
