RF133 Conexant Systems, Inc., RF133 Datasheet - Page 6

• Manufacturer Part Number: RF133
• Manufacturer: Conexant Systems, Inc.

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 transmit RF.
Even greater flexibility in the transceiver frequency planning is
possible because of the programmable dividers in the feedback
and the reference paths.
