Features - 1 Output Frequencies: 300 MHz to 4.8 GHz - Low-Noise VCO: - 133 d Bc/Hz (1-MHz Offset, f OUT = 2.65 GHz) - 13-/16-Bit Reference/Feedback Divider - 25-Bit Fractional-N and Integer-N PLL - Low RMS Jitter: 0.35 ps - Input Reference Frequency Range: 0.5 MHz to 350 MHz - Programmable Output Divide-by-1/-2/-4/-8 - Four Differential LO Outputs - External VCO Input with Programmable VCO On/Off Control 2 Applications - Wireless Infrastructure - Wireless Local Loop - Point-to-Point Wireless Access - Wireless MAN Wideband Transceivers 3 Description The TRF3765 is a wideband Integer-N/Fractional-N frequency synthesizer with an integrated, wideband voltage-controlled oscillator (VCO). Programmable output dividers enable continuous frequency coverage from 300 MHz to 4.8 GHz. Four separate differential, open-collector RF outputs allow multiple devices to be driven in parallel without the need of external splitters. The TRF3765 also accepts external VCO input signals and allows on/off control through a programmable control output. For maximum flexibility and wide reference frequency range, wide-range divide ratio settings are programmable and an offchip loop filter can be used. The TRF3765 is available in an RHB-32 VQFN package.
