Tx112-1-315MHz ASK Bill of Materials
FSK Operation
Table 2 and 3 describe the ASK operation for 433.92MHz and 315MHz.
Table 4 lists the component values that change between ASK or FSK operation. Please note that use of a high FSK data
rate may excite parasitic resonant modes with some crystal types. Recommended crystals from Table 2 and 3 are good
for both ASK and FSK.
