SPCA754A

The SPCA754A is one member of the SPCA754A family which is designed as the single chip signal processor that can be used in standalone audio players, the system controller can easily carry out the MPEG audio decoding process by the use of a general serial IO/control interface for MPEG bit stream in/out and playback control. Also this device is designed for 3.3V applications, A built in PLL is able to synthesize the system clock from a 16.934MHz crystal oscillator source.

Features of the SPCA754A are:(1)Single chip MPEG audio decoder: Conforming to MPEG1/MPEG2 audio layer 2/3 and Extension to MPEG lower sampling rates;(2)digital sound control: digital volume control, stereo/mono channel select and digital sound equalizer;(3)Internal auto-generate audio clock: Sampling frequency from 8 kHz up to 48 kHz;(4)Serial data IO and control interface: Easy for the host processor to command;(5)Low power dissipation;(6)Low power dissipation: Require only 16.934MHz crystal, resistors, and capacitors to supply the system clock.etc.

The absolute maximum ratings of the SPCA754A can be summarized as:(1)Supply Voltage: 0.0 to 3.6 V;(2)Input Voltage: -0.3 to VDD+0.3 V;(3)Operating Temperature: 0 to 60 ºC;(4)Storage Temperature: -55 to 125 ºC. The electrical characteristics of this device can be summarized as:(1)Supply Voltage: 3.0 V to 3.6 V;(2)Input Low Voltage: 0.2 VDD;(3)Input High Voltage: 0.8 VDD;(4)Output High Voltage: 2.4V to VDD;(5)Output Low Voltage: 0.3 V to 0.6 V;(6)Power Supply Current: 30.0mA to 40.0mA.
