MAX2870
23.5MHz to 6000MHz Fractional/
Integer-N Synthesizer/VCO
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 -40 N C to +85 N C
temperature range.
