5 / 16 page No. 5876-5/16 LC72709E, 72709W Continued from preceding page. Pin No. Pin Name Function I/O Circuit type LC72709E LC72709W Output VDDA VSSA VDDD VSSD 54 50 3, 14, 35, 15, 34, 62 37 34 2, 10, 24 11,23, 43 Analog system power supply Analog system ground Digital system power supply (4.5 to 5.5 V) Digital system ground — — — — NC 1, 4, 8, 12, 16, 17, 21, 25, 28, 32, 33, 37, 41, 45, 48, 49, 53, 56, 60, 64 – Not connection Note: A capacitor of at least 2000 pF must be inserted between VDDD and VSSD when using this IC. VREF 35 Reference voltage output (Vdda/2) 51 Data I/O Techniques • CCB Technique Sanyo audio ICs input and output data using the Sanyo CCB (computer control bus) standard, which is a serial bus format. This IC uses an 8-bit address CCB and uses the following addresses. • Data Input Timing I/O mode Address Function B0 B1 B2 B3 A0 A1 A2 A3 Input 0 1 0 1 1 1 1 1 16-bit control data input Output 1 1 0 1 1 1 1 1 Data output for the input clock (CL) Input 0 0 1 1 1 1 1 1 Data input (in 8-bit units) for the layer 4 CRC check circuit Internal data latching A10595 • Data Output Timing A10596 Note:The DO pin is normally left open. Since the DO pin is an n-channel open drain pin, the time required for the data to change from the low level to the high level depends on the value of the pull-up resistor. |
