DESCRIPTION
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,
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 (VCP) 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.
