Seamless DAB to FM Service Following (GL3142) Tri-Band RF Tuner integrated, Low power consumption DAB SoCGL314X is a low-power DAB/DAB+/DMB-audio/FM/MP3 baseband and audio processor with RF tuner for portable receivers and conventional receivers including kitchen radio. When an external FM receiver is connected, seamless service following between FM and DAB is possible. It integrates a triple-band RF tuner, an enhanced hardwired Eureka-147 demodulator, a FM/RDS demodulator, a programmable audio decoder which supports various formats, such as MUSICAM, HE-AAC V2 and OGG and a display controller into a single chip. An embedded 32-bit RISC processor takes care of internal operation as well as user applications. GL314X also integrates various analog and mixed-signal IPs such as audio DAC, USB 2.0 PHY, ADC, RTC, PLL, LDO and POR. These IPs minimize the requirement of external components. It also includes 2M or 8M byte SDRAM, so that no external working memory is required. For the SDRAM capacity, it is recommended to refer to the detail information of each device.GL314X can be utilized in either slave or master mode. In the slave mode, it can be controlled using various serial interfaces (SPI, I2C or UART). Flexible product configuration is supported by enriched interfaces such as serial interfaces (I2C, SPI, UART and IrDA), USB 2.0 high/full speed device, USB full/low speed host, SD card interface, LCD/local interface, I2S and SPDIF.The software development kit (SDK) covers from the RTOS to some application decoders such as SLS/DLS, EPG and TPEG. MOT/TDC protocol decoder, file system, graphic library are also provided along with wide range board specific packages.Especially, the low power architecture of GL314X is well suited for portable devices.
