MAX2870ETJ+ RF IC Fractional, Integer-N Synthesizer/ VCO General Purpose 23.5MHz ~ 6GHz 32-TQFN

General Description

The MAX2870 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 MAX2870 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 programmable to deliver

-4dBm to +5dBm output power. Both outputs can be

muted by either software or hardware control.

The MAX2870 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 -40NC to +85NC

temperature range
