KS8803B 10/15 CH PLL
INTRODUCTION
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 divid-
er for transmit and receive section and phase detector.
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
