SLWS146A − MARCH 2004 − REVISED NOVEMBER 2004

HIGH-PERFORMANCE INTEGER-N PLL FREQUENCY SYNTHESIZER

and a 13-bit B counter. The R divider allows the user to

FEATURES

select the frequency of choice for the phase-frequency

detector (PFD) circuit, and with the use of the counters

implement an N divider of value N = A + P x B. With an

extended charge-pump supply (V_CP) of up to 8 V, a wide

variety of external VCOs can be used to complete the

phase-locked loop. Ultra-low phase noise and reference

spur performance make the TRF3750 ideal for generating

the local oscillator in the most demanding wireless

applications.

Single Device Covers Frequencies Up to

2.4 GHz

Dual Supply Range: 3 V − 3.6 V and

4.5 V − 5.5 V

Separate Charge Pump Supply (V ) Up

to 8 V

Simple 3-Wire Serial Interface Allows for Fully

Programmable:

− A, B, and R Counters

− Dual Modulus Prescaler [8/9, 16/17, 32/33,

and 64/65]

− Charge Pump Current

CLOCK

The TRF3750 frequency synthesizer is ideal for designing

the local os cillator portion of wireless transceivers by

providing complete programmability and ultra-low phase

noise. The device features a user-selectable dual-

modulus prescaler, a 14-bit reference (R) divider, a 6-bit A,
