TRF3750 General Description
The TRF3750 frequency synthesizer is ideal for designing the local os cillator portion of wireless transceivers byN 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.
