Description

The ICD2051 Programmable Clock Generator offers two fully user-programmable phase-locked loops in a single package.

The outputs of the ICD2051 may be changed "on the fly" to any desired frequency value between 320 kHz and 100 MHz. The ICD2051 is ideally suited for any design where one or more multiple or varying frequencies are required, thus replacing more expensive metal can oscillators.

The capability to dynamically change the output frequency adds a whole new degree of freedom for the electrical engineer.

Some examples of the uses for this ICD2051 include: laptop computers, in which slowing the speed of operation can mean less power consumption or speeding it up can mean faster operation; graphics board dot clocks to allow dynamic synchronization with different brands of monitors or display formats; and on-board test strategies where the ability to skew a system's desired frequency (for example ±10%) allows worst case evaluations.
