Si4133G Derivative Devices

The Si4133G performs both IF and dual-band RF frequency synthesis. The Si4112G, Si4113G, Si4122G, and the

Si4123G are derivatives of this device. Table 13 outlines which synthesizers each derivative device features as

well as which pins and registers coincide with each synthesizer.
