MAX9491ETP045+T Description

Short technical summary and product information.

The MAX9491ETP045+T is a multipurpose clock generator designed for communication applications. It features a factory-programmable PLL output capable of generating frequencies ranging from 4MHz to 200MHz. The device utilizes a one-time-programmable (OTP) ROM for programming the PLL output.

 

Key features include an integrated voltage-controlled crystal oscillator (VCXO) with a wide ±200ppm tuning range, low RMS jitter (< 13ps at 197 MHz), and a 3.3V supply voltage. The operating temperature range is specified from -40°C to +85°C.

 

This clock generator is available in a 20-pin TQFN (5mm x 5mm) package, suitable for surface mount applications. Its design makes it ideal for telecommunications, data networking systems, home entertainment centers, and SOHO environments.

 

The MAX9491ETP045+T supports LVCMOS and Crystal inputs and provides an LVCMOS output. It is a single-circuit device with a 1:1 frequency ratio and no differential clock or divider functions.
