AV9170
Block Diagram
Clock Synchronizer and Multiplier
AV 9170 Rev E 9/24/99
On-chip Phase-Locked Loop for clocks synchronization
Synchronizes frequencies up to 107 MHz
(output) @ 5.0V
1ns skew (max) between input & output clocks @ 5.0V
Can recover poor duty cycle clocks
CLK1 to CLK2 skew controlled to within 1ns @ 5.0V
3.0 - 5.5V supply range
Low power CMOS technology
Small 8-pin DIP or SOIC package
On chip loop filter
AV9170-01, -04 for output clocks 20-107 MHz @ 5.0V,
20 - 66.7 MHz @ 3.3V
AV9170-02, -05 for output clocks 5-26.75 MHz @ 5.0V,
5 - 16.7 MHz @ 3.3V
The AV9170 generates an output clock which is synchronized
to a given continuous input clock with zero delay (1ns at 5V
V
DD
). Using ICSs proprietary phase-locked loop (PLL) ana-
log CMOS technology, the AV9170 is useful for regenerating
clocks in high speed systems where skew is a major concern.
By the use of the two select pins, multiples or divisions of the
input clock can be generated with zero delay (see Tables 2 and
3). The standard versions produce two outputs, where CLK2
is always a divide by two version of CLK1.
The AV9170 is also useful to recover poor duty cycle clocks.
A 50 MHz signal with a 20/80% duty cycle, for example, can
be regenerated to the 48/52% typical of the part.
The AV9170 allows the user to control the PLL feedback,
making it possible, with an additional 74F240 octal buffer (or
other such device that offers controlled skew outputs), to
synchronize up to 8 output clocks with zero delay compared to
the input (see Figure 1). Application notes for the AV9170 are
available. Please consult ICS.
ICS reserves the right to make changes in the device data identified in this publication
without further notice. ICS advises its customers to obtain the latest version of all
device data to verify that any information being relied upon by the customer is current
and accurate.

AV9170
The AV9170 has the following characteristics:
1. Rising edges at IN and FBIN are lined up. Falling
edges are not synchronized.
2. The relationship between the frequencies at FBIN and IN
with CLK1 feedback is shown in Table 1 below.
3. The frequency of CLK2 is half the CLK1 frequency.
4. The CLK1 frequency ranges are:
The AV9170 will only operate correctly within these
frequency ranges.
Using the AV9170
Eliminate High Speed
Clock Routing Problems
The AV9170 makes it possible to route lower speed clocks
over long distances on the PC board and to place an AV9170
next to the device requiring a higher speed clock. The
multiplied output can then be used to produce a phase locked,
higher speed output clock.
Compensate for Propagation Delays
Including an AV9170 in a timing loop allows the use of PALs,
gate arrays, etc., with loose timing specifications. The
AV9170 compensates for the delay through the PAL and
synchronizes the output to the input reference clock.
Operating Frequency Range
The AV9170 is offered in versions optimized for operation
in two frequency ranges. The -01 and -04 cover high
frequencies, 20 to 100 MHz.* The -02 and -05 operate from
5 to 25 MHz.* The AV9170 can be supplied with custom
multiplication factors and operating ranges. Consult ICS for
details.
3.3V VDD Operation
The AV9170 does operate at both 5.0V and 3.3V system
conditions. Please note the Electrical Characteristic specifica-
tions at 3.3V include a limited output frequency (66.6 MHz
max.) and a wider skew of FBIN to CLK1. For 3.3V5%
(3.15V min.), this skew is -5.0 to 0 ns. At 3.3V10% (3.0V
min.), the skew is widened to -8 ns to 0 ns and should be
accounted for in system design.
*At 3.3V, the maximum CLK1 frequency is 66.7 MHz for -01,
-04 and 16.7 MHz for -02, -05.

AV9170
*Parameter guaranteed by design and characterization. Not 100% tested in production.
Notes:
1. It may be possible to operate the AV9170 outside of these ranges. Consult ICS for your specific application.
2. All AC Specifications are measured with a 50W transmission line, load terminated with 50W to 1.4V.
3. Duty cycle measured at 1.4V.
4. Skew measured at 1.4V on rising edges. Positive sign indicates the first signal precedes the second signal.

AV9170
General Layout Precautions:
1) Use a ground plane on the top layer
of the PCB in all areas not used by
traces.
2) Make all power traces and vias as
wide as possible to lower
inductance.
Notes:
1) All clock outputs should have series
terminating resistor. Not shown in all
places to improve readibility of
diagram.
Connections to VDD:
