Serial Input PLL Frequency Synthesizer

INTRODUCTION:
The KS8805B is a superior low power-programmable dual frequency synthesizer (PLL) which can be used in high performance CT-1 cord-less phone system with frequency range under 60 MHz in all over the world.
This device has two independent phase detectors and channel divider block for transmitter and receiver part. It includes reference divider and auxiliary reference divider to generate independent reference frequency using a common reference oscillator. If required, all divider blocks can be fully programmed through MICOM serial interface.
FEATURES:
Operating voltage range : 3.0 ~ 5.5V
Superior supply current : 2.5mA (Typ) at 3.0V
Included power saving mode function which can control the each register block according to program data of MICOM
Included clock output with frequency of X-tal OSC 3 / 4 for MICOM or other system and clock output on / off control by MICOM
Superior Max operating frequency range : 60MHz at 300 mVp-p, VDD = 3.0V
Internal reference oscillator can support the external X-tal which oscillates up to 16MHz
Built - in Lock detect signal output
Internal reference divider range : 16 ~ 4095
Internal Auxiliary reference divider range : 16 ~ 16383
Internal RX (TX) divider range : 16 ~ 65535

5fMCUClock output terminal.
This output pin provides the clock source for Micom or other system as an output of X - tal OSC 3 / 4. Which can be controlled by the bit of the control register. Clock output on / off control is possible by MICOM.
6GNDGround
7RIX-tal Oscillator Input
8ROX-tal Oscillator Output
9RIF Input terminal of RX channel counter. Usually, AC coupled output signal of VCO loop is introduced and the Minimum input signal level is 300mVp-p at 60 MHz
10PDR There are 3 - kind output signal states in PDR pin.
- If fRX > fREF (fRX is leading), the output is negative pulse state
- If fRX - If fRX = fREF (the same phase), the output is high impedance state
11PWDRX This output terminal offers the state of internal RX channel counter operation. If this pin state is high, internal RX channel counter is operating in power saving mode. So, this pin can be used in appling the power switch on / off control.
12VDDPower supply input terminal
13PWDTX If this pin state is high, internal TX channel counter is operating in power saving mode. So, this pin can be used in appling the power switch on / off control.
14TIF Usually, AC coupled output signal of VCO loop is introduced and the Minimum input signal level is 300mVp-p at 60 MHz
15PDT There are 3 - kind output signal states in PDT pin.
- If fTX > fREF (fTX is leading), the output is negative pulse state
- If fTX - If fTX = fREF (the same phase), the output is high impedance state
16LDT Output terminal of lock detection waveforms
This output pin is internally connected with TX - loop. High output state in LDT pin indicates out of internal operation.
