YSS241B

The YSS241B (DPLD2) is a Dolby Pro Logic Decoder LSI, offering high quality sound processing by all digital sound processing.There are some features as follows.First is Dolby Pro Logic Decoder block.The second is digital interface for audio signals with 2 channels for input and up to 5 channels for output.Then is direct interface with ITT Semiconductor's MSP3410 through digital interface.Next is 2nd-order IIR filter for front 3 channel (L,R,C) to compensate speaker characteristics.Besides,a sampling frequency (fs) can be selected from 32 kHz,44.1 kHz or 48 kHz.Furthermore, master clock can be selected from 256 fs or 18.432 MHz (576*32 kHz).The seventh one is that the control of parameters from external microprocessor is made through serial 3-line or I2C bus interface.The last one is 5 V single power supply, Si-gate CMOS process.

What comes next is about the absolute maximum ratings of YSS241B.The VDD (power supply voltage) is from -0.5 V to +0.7 V.The VI,VO (input voltage,output voltage) is from -0.5 V to VDD+0.5 V.The Top (operating temperature) is from 0 to 70.The Tstg (storage temperature) is from -50 to +125.Then is about the recommended operating conditions.The minimum VDD (power supply voltage) is 4.75 V,the typical is 5.00 V and the maximum is 5.25 V.The minimum Top (operating temperature) is 0, the typical is 25 and the maximum is 70.

The following is about the DC characteristics of YSS241B (condition: Top=0 to 70,VDD=5.0±0.25 V).The maximum IDD (power supply current) is 90 mA at VDD=5.25 V.The minimum VIH (input high voltage) is 0.7VDD V.The maximum VIL (input low voltage) is 0.3VDD V.The minimum ILK (input leakage current) is -10A and the maximum is 10A.The maximum CI (input terminal capacitance) is 8 pF.The maximum CO (output terminal capacitance) is 10 pF when no load.The maximum CI/O (I/O terminal capacitance) is 10 pF when no load.
