LC72151V Datasheet(HTML) 9 Page - Sanyo Semicon Device |
9 / 29 page Serial Data I/O Methods Data is input to and output from the LC72151V using the Sanyo CCB (Computer Control Bus) format, which is the serial bus format used by SANYO audio ICs. This IC adopts a CCB format with an 8-bit address. No. 6976-9/29 LC72151V I/O mode Address Content B0 B1 B2 B3 A0 A1 A2 A3 • Control data input (serial input) mode.

Pin No. Symbol Usage Function Pin circuit • Output buffer for the crystal oscillator circuit • When XB in the serial data is set to 1, the output buffer operates and the crystal oscillator signal (a pulse signal) is output. When XB is 0, XBUF outputs a low level. After the power-on reset, the output buffer is fixed at the low level. 4 XBUF Crystal oscillator buffer XOUT |
