Pll Based Frequency Synthesizer IC Chip MAX2871ETJ+ With Integrated Vcos

MAX2871ETJ+ Low Normalized Inband Phase Noise of -230dBc/Hz SYNTHESIZER IC

General Description

The MAX2871 is an ultra-wideband phase-locked loop (PLL) with integrated voltage control oscillators (VCOs) capable of operating in both integer-N and fractional-N modes. When combined with an external reference oscillator and loop filter, the MAX2871 is a high-performance frequency synthesizer capable of synthesizing frequencies from 23.5MHz to 6.0GHz while maintaining superior phase noise and spurious performance. The ultra-wide frequency range is achieved with the help of multiple integrated VCOs covering 3000MHz to 6000MHz, and output dividers ranging from 1 to 128. The device also provides dual differential output drivers, which can be independently programmed to deliver -1dBm to +8dBm differential output power. Both outputs can be muted by either software or hardware control. The MAX2871 is controlled by a 3-wire serial interface and is compatible with 1.8V control logic. The device is available in a lead-free, RoHS-compliant, 5mm x 5mm, 32-pin TQFN package, and operates over an extended -40°C to +85°C temperature range. The MAX2871 has an improved feature set and better overall phase noise and is fully pin- and software- compatible with the MAX2870.
