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

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,
