Integer-N/Fractional-N PLL with Integrated VCO

Check for Samples: TRF3765

FEATURES

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.

•

Output Frequencies: 300 MHz to 4.8 GHz

•

Low-Noise VCO: –133 dBc/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

The TRF3765 also accepts external VCO input

signals and allows on/off control through

•

Programmable Output Divide-by-1/-2/-4/-8

Four Differential LO Outputs

programmable control output. For maximum flexibility

and wide reference frequency range, wide-range

divide ratio settings are programmable and an

off-chip loop filter can be used.

External VCO Input with Programmable VCO

On/Off Control

The TRF3765 is available in an RHB-32 QFN

package.
