Description
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 output power. Both outputs can be muted by either software or hardware control.
The MAX2871 is controlled by a 4-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.
