SC8803 Description
SC8803 is a programmable PLL circuit used for 10 channels transceiver. It is designed for cordless phone with frequency is 46/49MHz, frequencies of receive and transmit are controlled by pin D0~D3, and frequencies are different for base mode and remote mode. Unlock detect circuits are integrated here, and the lock_det pin outputs the lock state.
SC8803 Key Features
- 10 Channels selectable:(both transmit / receive)
- Include oscillation circuit with external x-tal (10.24MHz)
- Unlock detector (phase difference more than 6.25 s)
- Stand-by function for power saving
