LMX2572RHAR

The LMX2572 is a low-power, high-performance
wideband synthesizer that can generate any
frequency from 12.5 MHz to 6.4 GHz without using an
internal doubler. The PLL delivers excellent
performance while consuming just 75 mA from a
single 3.3-V supply.
For applications like digital mobile radio (DMR) and
wireless microphones, the LMX2572 supports FSK
modulation. Discrete level FSK and pulse-shaping
FSK are supported. Direct digital FSK modulation is
achievable through programming or pins.
The LMX2572 allows users to synchronize the output
of multiple devices and also enables applications that
need deterministic delay between input and output.
The LMX2572 provides an option to adjust the phase
with fine granularity to account for delay mismatch on
the board or within devices. A frequency ramp
generator can synthesize up to two segments of ramp
in an automatic ramp generation option or a manual
option for maximum flexibility. The fast calibration
algorithm allows the user to change frequencies
faster than 20 µs. The LMX2572 also supports
generating or repeating SYSREF (compliant to
JESD204B standard) making it an ideal low-power,
low-noise clock source for clocking high-speed data
converters. Fine delay adjustment is provided in this
configuration to account for delay differences of board
traces.
The LMX2572 integrates LDOs from a single 3.3-V
supply, thus eliminating the need for onboard lownoise LDOs.
