Hi everybody, I had looked for an IC as a soft modem codec with UART connection. I want to use ALIS-D of siemens but
ALIS has two serial connections A Control Interface with 4 pins DCLK: data clock which can be 1 khz to 1024 khz DIN: Data input DOUT: Data output CS: Chip select for register write or read data is 8 bit serial no parity no start or stop bit this channel is used to configure internal registers of alis B Data Interface with 4 pins for 16 bit serial codec input and output data DAT_CLK :dat clock,128 khz to 1024 khz FSC :Frame syncronization clock, 8khz which alerts start of a new 16 bit sampled data transfer. DAT_IN :Transmit Data input DAT_OUT :Receive Data output Data is 16 bit no parity no start or stop bit. ALIS accepts 16 bit Transmit data input syncronized with FSC which activated every 125 Us since 8 Khz clock. here I faced up with two (8 bit and 16 bit) synchronous interfaces but I want to use a standart UART port for connection. Do you know any chips for following tasks (A) 16 bit synchronous to asynchronous convertor where asynchronous interface is from UART (B) 8 bit synchronous to asynchronous convertor where asynchronous interface is from UART Or is there any parallel interface solutions for codec connections which is attached to data and address bus of CPU. Do you know any IC for this purpose? Best regards, Hal?k U?ar
