YSS220

The YSS220 is an LSI which has surround capability by digital audio technology. The features of YSS220 can be summarized as (1)built-in 15-bit floating ADC enable digital processing for analog signals with 32kHz internal sampling frequency; (2)4 channels except center output digital signals as well; (3)hi-performance surround by mixing many echoes with using up to 512ms digital delay; (4)preset mode for easy control by terminal setting.

The absolute maximum ratings of the YSS220 are: (1)power supply voltage, VDD: -0.3 to 7.0 V; (2)input voltage, VI: -0.3 to VDD+0.5 V; (3)operating temperature, Top: -40 to 85; (4)storage temperature, Tstg: -50 to 125.

The following is about the electrical characteristics of YSS220: (1)power supply current: 225mA max at VDD=5.0V; (2)input highlevel voltage: 2.2V min; (3)input lowlevel voltage: 0.8V max; (4)output highlevel voltage: VDD-1.0V min at IOL=0.4mA; (5)output lowlevel voltage: 0.4V max at IOH=-1.6mA; (6)input capacitance: 10pF max; (7)input leakage current: 10A max.
