TRF3750 - TRF3750：高性能整数 N PLL 频率合成器 - 无 - RFPPL与合成器 - TI公司（Texas Instruments，德州仪器）
The TRF3750 frequency synthesizer is ideal for designing the local oscillator 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 × 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.
