... Ordering number : EN4333A Overview The LC8902 and LC8902Q are receiver LSIs for applications in which data is transmitted between digital audio equipment in the EIAJ format. These LSIs synchronize with the input signal and demodulate that signal to a regular format signal. Features • Built-in PLL circuit synchronizes with the input EIAJ format signal. • ...

... Digital source mode: EIAJ CP-1201 format data reception mode Analog source mode: Analog data is received and converted to digital for signal processing. This figure shows an example of a structure using the LC8902/Q. In analog source mode the only function of the LC8902 provide control clocks. ...

... The LC8902/Q uses the subcode synchronization word and the start bit in the user bits for subcode interface system timing extraction. Therefore, SBSY and SFSY change depending on that timing. Keep the following notes on user bit transfer in mind when using the values of tBW, tF, tCHW and tCD within the specifications described above. Basically, user bit transfers must follow the table shown here ...

... Block Diagram Clock Modes The LC8902/Q CLKOUT1 and CLKOUT2 output clock modes are selected by the CLK and CLKMD pins according to the table. CLK CLK OUT1 L 384 fs clock output H 512 fs clock output CLK MD CLK OUT2 L 256 fs clock output* H 128 fs clock output Note: * When the CLK pin is low, the 256 fs clock duty has a high to low ratio of 2:1. ...

... Note: Setting the data demodulation input code to one of the XSYS settings switches the system clock from the VCO to the crystal oscillator and sets the LC8902/Q to analog source mode. Selecting one of the input pins once again sets the LC8902/Q to digital source mode and PLL operation. ...

... CD Subcode Interface The LC8902/Q uses the SFSY, SBCK, PW and SBSY pins to output the CD subcode data. This data is the user bits that were transferred according to the CP-1201 interface format and converted to a format that conforms to the CP-2401 interface format. The timing is shown in the figures. ...

... VCO or the crystal oscillator clock. When power is first applied, the clock is supplied from the VCO, and the LC8902/Q switches to the crystal oscillator data state is detected. Here clock signal was not supplied from the crystal oscillator after a no data state is detected, the whole system would stop and remain in the stopped state, since the detection circuit would not operate even if data were supplied ...
