LC89058W - Brand New SANYO Special Purpose Audio ICs
-
Description
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. It incorporates a number of features for its low cost and is optimal for receiving digital data for AV amplifiers and receivers.
Specifications and Features
- 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
- 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
- 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
- Supports I2S data output that facilitates interfacing with DSP
- 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)
- SQFP48 packageApplication Scenarios
The LC89058W-E is ideal for applications in AV amplifiers and receivers, specifically for receiving digital data.
