YM3437C

The YM3437C is a serial digital audio transmitter LSI. DIT2 can convert 4 different kinds of serial digital audio data into EIAJ CP-340 or AESIEBU digital audio interface format. YM3437C has capabilities of outputting with the 24-bit output and also setting the channel status, user data, etc.The audio data and control code taken in are bi-phase modulated and output from the DOUT terminal. Whether to set the audio data processing length to 20 bits (or 16 bits for the DIN (4) of the input format) or 24 bits depends on the control code input mode. (Refer to the description in the previous section.)

Features of the YM3437C are:(1)operation synchronous with the external clock signals inputted through the MCLK terminal; (2)useable for either 24-bit output by using the auxiliary bit of the digital audio interface signal or 20-bit output; (3)all of the validity flag, channel status and user data can be set as a control code:synchronous mode; all bits of the validity flag, channel status and user data can be set synchronous with the audio data,asynchronous mode; the first 32 bits of each of the channel status and user data can be set independently from the audio data timing; (4)the output data can be muted according to the MUTE signal from outside; (5)5V power supply, si-gate CMOS, 16-pin DIP and 16-pin SOP.

The absolute maximum ratings of the YM3437C can be summarized as:(1)power supply voltage:-0.3 to 7.0 V;(2)storage temperature:-50 to +125;(3)input voltage:Vss-0.3 to Vdd=0.5V;(4)operating temperature:0 to +85.These Yamaha Products are designed only for commercial and normal industrial applications, and are not suitable for other uses, such as medical life support equipment,nuclear facilities, critical care equipment or any other application the failure of which could lead to death, personal injury or environmental or property damage.
