KS8803B
10/15 CH PLL
INTRODUCTION
16-DIP-300A The KS8803B/4B are designed to select 10/15 channels of cordlss phone of which frequency band is 46/49MHz. It has reference frequency generator, programmable divider for transmit and receive section and phase detector.
16-SOP-225
FEATURES
* 10 Channels selectable : KS8803B (both transmit/receive) * 15 Channels selectable : KS8804B (both transmit/receive) * Include oscillation circuit with external x-tal (10.24MHz) * 5KHz output for guard tone * Unlock detector (phase difference more than 6.25us) * Stand-by function for power saving
