Note! The ICS1572 was made in 2 versions with suffixes 101 or 301 here we have the 301 type, see notes below.
Description
The ICS1572 is a high performance monolithic phase-locked
loop (PLL) frequency synthesizer. Utilizing ICS’s advanced
CMOS mixed-mode technology, the ICS1572 provides a low
cost solution for high-end video clock generation in worksta-
tions and high-end PC applications.
The ICS1572 has differential video clock outputs (CLK+ and
CLK-) that are compatible with industry standard video DACs.
Another clock output, LOAD, is provided whose frequency is
derived from the main clock by a programmable divider. An
additional clock output is available, LD/N2, which is derived
from the LOAD frequency and whose modulus may also be
programmed.
Operating frequencies are fully programmable with direct con-
trol provided for reference divider, pre-scaler, feedback divider
and post-scaler.
Reset of the pipeline delay on Brooktree RAMDACs may
be performed under register control. Outputs may also be set
to desired states to facilitate circuit board testing.
Features
• Supports high-resolution graphics – CLK output to 180 MHz
• Eliminates need for multiple ECL output crystal oscillators
• Fully programmable synthesizer capability – not just a clock multiplier
• Available in 20-pin 300-mil wide body SOIC package
• *Available in both parallel (101) and serial (301) programming versions * see notes below
• Circuit included for reset of Brooktree RAMDAC pipeline delay
*The ICS1572-101 supports phase detector
disable via a special control mode. When the
PDRSTEN (phase detector reset enable) bit is
set, a high level on AD3 will disable PLL locking.
*The ICS1572-301 supports phase detector
disable via the BLANK pin. When the
PDRSTEN bit is set, a high level on the
BLANK input will disable PLL locking.
Applications
• Workstations
• AutoCad Accelerators
• High-end PC graphics systems

PLEASE NOTE!
These parts came to us as part of a lot of surplus stock from a large distribution Co. and have been kept in storage for a time, we have therefore classified them as new other, they are however unused and in good serviceable condition, stored with us still in original tubes – the photographs are of one of our actual stock, and, as with all our products they come with a full guarantee.
If you have similar items to this, or indeed any electronic components that are surplus to requirements please contact us with details.
