I'm designing calling line identifier equipment that use FSK demodulation IC and interface with microcontroller 89C51 foward serial tranfer. But I have trouble with FSK receiver IC.
In Vietnam , I can't buy this FSK receiver IC . That is FSK receiver( MC145447) . I don't know way to buy this IC at Vietnam.
Can you send to my company schematic, some this IC to research,introduce some codes for interface 8051 with Caling Line Identifier service, some ways to display 58 7 segment LED, their DATASHEETs and show me way to oder this IC from your company.
Can you show me where I can buy this IC at Vietnam and send datasheet to understand Motorola Hex File format
I hope you reply and mail to me as soon as possible.
I wish you contact with my company to send this IC
Thank you.
