The Samsung KS8803B is an integrated circuit designed to select 10 channels of cordless phone operation within the 46/49MHz frequency band. The device includes a reference frequency generator, programmable dividers for both transmit and receive sections, and a phase detector.
Key features include support for a 10.24MHz external crystal oscillator, an S5KHz output for guard tones, an unlock detector, and a stand-by function to reduce power dissipation. The chip is available in two packages: the 16-DIP-300A and the 16-SOP-225.
| Supply Voltage (Vop) | 3.0 ~ 5.5 V |
|---|---|
| Operating Temperature | -30°C ~ +75°C |
| Power Dissipation (Pp) | 350 mW |
| Reference Frequency | 10.24 MHz |
| Guard Tone Output | 5 KHz |
The MODE pin selects between Base Unit and Remote Unit operations.
Setting the SB pin to Low puts the device in stand-by mode for power saving.
The minimum input voltage is 0.1Vrms.
