TDA7553規(guī)格書詳情
DESCRIPTION
The TDA755X family is a high performances, fully programmable 24-bit, 50 MIPS Digital Signal Processor (DSP), designed to support several speech and audio applications, as Automatic Speech Recognition, Speech Synthesis, Speaker Verification, Echo and Noise Cancellation. Software for these applications is licenced by Lernout & Hauspie and NCTI.
It offers an effective solution for this kind of applications because of the A/D and D/A converters and the big amount of memory integrated on chip.
■ 24-BIT, FIXED POINT, 50 MIPS DSP CORE
■ LARGE ON-BOARD PROGRAM ROM AND DATA RAM (UP TO 16Kw ROM/RAM AND 16Kw RAM)
■ INTEGRATED STEREO A/D AND D/A, 16-BIT SIGMA-DELTA
■ PROGRAMMABLE CODEC SAMPLE RATE FROM 4 TO 48 kHz
■ ON-BOARD PLL FOR CORE CLOCK AND CONVERTERS
■ MANAGEMENT OF EXTERNAL FLASH/SRAM/DRAM MEMORY BANK
■ I2C OR SPI SERIAL INTERFACE FOR EXTERNAL CONTROL
■ 80-PIN TQFP, 0.65 mm PITCH
■ AUTOMOTIVE GRADE (FROM -40° C to +85°C)
APPLICATIONS
Real time digital speech and audio processing:
speech recognition, speech synthesis, speech compression, echo cancelling, noise cancelling, speaker verification.
