Functional Description
The ICD2061A Dual Programmable Graphics Clock Genera-
tor features a fully programmable set of clock oscillators which
can handle all frequency requirements of most graphics sys-
tems. The ICD2061A offers the selection ease of ROM-based
clock chips, while also offering the versatility of serially pro-
grammable frequency synthesizers. It features advanced
power-down capabilities, making it ideally suited for the porta-
ble computer market. The ICD2061A has extended frequency
range and improved voltage/temperature stability when com-
pared to first-generation frequency synthesizers.
The ICD2061A Dual Programmable Graphics Clock Genera-
tor 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 oscilla-
tor devices. Some examples of the uses for this device in-
clude: laptop computers, in which slowing the speed of oper-
ation can mean less power consumption or speeding it up can
mean faster operation; graphics board dot clocks to allow dy-
namic synchronization with different brands of monitors or dis-
play formats; and on-board test strategies where the ability to
skew a system’s desired frequency (for example: ±10%) al-
lows 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.
