ICS1522
Power-On Initialization
The
ICS1522
has an internal power-on reset circuit that
sets the frequency of the CLK+and CLK- outputs to be half
the crystal or reference frequency assuming that they are
between 10 MHz and 25 MHz (refer to default settings in
Register Definition). Because the power-on reset circuit is
on the VDD supply, and because that supply is filtered,
care must be taken to allow the reset to de-assert before
programming. A safe guideline is to allow 20 microseconds
after the VDD supply reaches four volts.
Board Test Support
It is often desirable to statically control the levels of the
output pins for circuit board test. The
ICS1522
supports
this through a register programmable mode, AUXEN. When
this mode is set, AUXCLK will directly control the logic
levels of the CLK+ and CLK- pins while OMUX1, OMUX2,
OMUX3, and OMUX4 will control OUT1, OUT2, OUT3
and OUT4, respectively.
Pin Discriptions
Power Supplies and Decoupling
The
ICS1522
has three
VSS
pins to reduce the effects of
package inductance. Both pins are connected to the same
potential on the die (the ground bus). These pins should
connect to the ground plane of the video board as close to
the package as is possible.
The
ICS1522
has a
VDDO
pin which is the supply of +5
volt power to all output drivers. This pin should be connected
to the power plane (or bus) using standard high-frequency
decoupling practice. That is, capacitors should have low
series inductance and be mounted close to the
ICS1522
.
The
VDD
pin is the power supply pin for the PLL synthesizer
circuitry and other lower current digital functions. We
recommend that RC decoupling or zener regulation be
provided for this pin (as shown in the recommended
application circuitry). This will allow the PLL to “track”
through power supply fluctuations without visible effects.
