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.
