Note 7) Current supplied to the charge pump f or local oscillators 1 and 2 can be set independently in systems.

Howev er,when power supply is turned of f , the charge pump output is placed in "HiZ" status regardless

of set v alue.

Note 8) The div ision ratio of the programmable div ider f or comparison f requency is giv en in 13-bit binary code.

For transmission local oscillator N(Fref ) = 4 * P Howev er, P = 20 to 8191

For reception local oscillator N(Fref ) = 2 * P Howev er, P = 20 to 8191

Note 9) The div ision ratio of programmable div ider f or local oscillators 1 and 2 are giv en in 17-bit binary code.

For transmission local oscillator N(Fv c oTX) = 256 to 131071

For reception local oscillator N(Fv c oRX) = 1024 to 131071
