PIN DESCRIPTION
Name
Description
Crystal connection pins.
A 3.6864 MHz or 7.3728 MHz crystal shall be connected.
When an external clock is applied for MSM6882's oscillation source, it has to be input to X2.
In this case, X2 has to be AC-coupled by the capacitor of 200 pF. X1 shall be left open.
Master clock selection.
X1
MCS
Modulator enable.
When a "high" is input on this pin, MSK modulator output is connected to the input of transmit
LPF.
When a "low" is input on this pin, TI is connected to the input of transmit LPF.
Send data input.
The data on this pin is synchronized with the rising edge of ST and input to MSK modulator
as an actual transmit data.
ME
MSK Modulated Data
SD
ST
SD
This timing signal is used to latch serial input data on the SD pin.
The frequency of ST coincides with the transmission bit rate.
Modulation method selection.
Data put on this pin selects either SINE FAST FSK or COSINE FAST FSK.

Preamble or data transmission selection.
When a "low" is input on this pin, the data put on the SD pin is output on the AO pin.
When a "high" is input on this pin, the data put on the SD pin is neglected and preamble data
is output.
Data put on PRE is latched on the rising edge of ST.
Preamble means to modulate as 010101...pattern.
