MAX9491 - Factory-Programmable - Single PLL Clock Generator

Description

The MAX9491 multipurpose clock generator is ideal for communication applications.

It offers a factory-programmable 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.

Features

  • an integrated voltage-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 specified 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.
