Description

1

OSCO

This output generates the reference frequency when it is connected to Pin 16 with the

external OSC, whose frequency is 10.24MHz.

2

MODE

Base/Remote Unit Selection Pin.

“High”: Base Unit

“Low” : Remote Unit

3

SB

Standby pin. This input controls Tx PLL for reducing the power dissipation

“High”: Normal operation

“Low”: Standby

D2, D3

Channel selection pins

The Combinations of these inputs select one channel among the 10 channels

9

TIF

Input to programmable divider of Tx. AC coupling with VCO

In case of a larger signal, It needs DC

−coupling. Minimum input voltage is 0.1 Vrms

10

LDT

Unlocked signal out pin (see output characteristics)

11

PDT

Phase detector output for Tx.

PDT detects the phase error from Tx PLL and its output is connected to the external

low pass filter

12

VSS

This pin is the negative supply of the IC. It is usually grounded

13

PDR

Phase detector output for Rx. PDR detects the phase error from Rx PLL and its output

is connected to the external low pass filter

14

RIF

Input of programmable divider for Rx. AC coupling with VCO

In case of a larger signal (standard CMOS logic), it needs DC coupling.

Minimum input voltage is 0.1Vrms

15

This pin is the positive supply of the IC

16

OSCI

X-TAL OSC connection pin

This input generates the reference frequency when it is connected to pin 1 with the

external OSC
