General Description
The MAX9491 multipurpose clock generator is ideal for
communication applications. It offers a factory-program-
mable PLL output that can be set to almost any frequency,
ranging from 4MHz to 200MHz. The MAX9491 uses a
one-time-programmable (OTP) ROM to program the PLL
output. The MAX9491 also features an integrated volt-
age-controlled crystal oscillator (VCXO) that is tuned by a
DC voltage. The VCXO output is used as the PLL input.
The VCXO has a wide ±200ppm (typ) tuning range. The
OTP on the MAX9491 is factory preset, based upon the
customer request. Contact the factory for samples with
preferred frequencies.
The device operates from a 3.3V supply and is speci-
fied over the -40
°
C to +85
°
C extended temperature
range. The MAX9491 is available in 14-pin TSSOP and
20-pin TQFN (5mm x 5mm) packages.
