ICD2061A

The ICD2061A Dual Programmable Graphics Clock Generator features a fully programmable set of clock oscillators which can handle all frequency requirements of most graphics systems.

The ICD2061A offers the selection ease of ROM-based clock chips, while also offering the versatility of serially programmable frequency synthesizers. It features advanced power-down capabilities, making it ideally suited for the portable computer market. The ICD2061A has extended frequency range and improved voltage/temperature stability when compared to first-generation frequency synthesizers.

The ICD2061A Dual Programmable Graphics Clock Generator offers two fully user-programmable phase-locked loops in a single package. The outputs may be changed "on the fly" to any desired frequency value between 390 KHz and 100 MHz.

The ICD2061A is ideally suited for any design where multiple or varying frequencies are required, replacing more expensive metal can oscillators.

Being able to change the output frequency dynamically adds a whole new degree of freedom for the electrical engineer which was previously unavailable with existing crystal oscillator devices. Some examples of the uses for this device 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.

While primarily designed for the graphics subsystem market, the programming versatility of the ICD2061A makes it ideal wherever two variable, yet highly accurate clock sources are required.
