VCC − 0.3 to

VCC (V)

MS1 : L TCXO : 19.2 MHz

MS2 : H

MS1 : H TCXO : 14.4 MHz

MS2 : L

MS1 : H TCXO : 26 MHz

MS2 : H

Output pin of charge pump. Connect external

R and C to this pin to set a dumping factor and

natural angular frequency (Isink = Isource = 0.45

mA).

13 Refin

Reference frequency input pin. Connect an

external reference transmitter (such as

TCXO) to this pin.

14 PLLVCC

Power supply voltage pin of PLL.

Connect a bypass capacitor to this pin to

reduce the high-frequency impedance.

15 PLLGND

Ground pin of PLL.

16 CLKout

Clock (fTCXO) output pin (IC test pin).
