The charge pump current can be programmed to be either 1 mA
or 0.5 mA and the translation loop can also be programmed to
allow for high side or low side injection of the first LO input with
respect to the transmt RF.
Even greater flexibility in the transceiver frequency planning is
possible because of the programmable dividers in the feedback
and the reference paths.
The absolute maximumratings of the RF133 are provided in
Table 3, and the electrical specifications are provided in Table 4.
Tables 5, 6, and 7 detail the setting of the programmable
operation modes. Figure 6 illustrates the timng of the three-wire
bus control signal and Figure 7 provides a graph of the input
compression versus the receiver gain.
Figure 8 shows a typical application circuit diagram Figure 9
provides the package dimensions for the 48-pin device.
