Data Flow
[FAX Tx]
(KX -MB1520/KX-MB1530 ONLY)
1. An analog image data is output from CIS unit to IC503.
IC503 decode the analog data to digital data, and output to IC300.
Scanner I/F in IC300 process image data and store it in IC400
through SDRAM I/F.
Scanner I/F in IC300 process image data and store it in IC400
through SDRAM I/F.
2. CPU compress the data in IC400.
3. CPU transfer the data to MODEM and output it to TEL LINE
3. CPU transfer the data to MODEM and output it to TEL LINE
through AFE IC and analog circuit.
