Functional Description
The CY2071A is a general-purpose clock synthesizer de-
signed for use in applications such as modems, disk drives,
CD-ROM drives, video CD players, games, set-top boxes, and
data/telecommunications. The device offers up to three con-
figurable clock outputs in an 8-pin, 150-mil SOIC package and
can operate off either a 3.3V or 5V power supply. The on-chip
reference oscillator is designed for 10-MHz to 25-MHz crys-
tals. Alternatively, an external reference clock of frequency be-
tween 1 MHz and 30 MHz can be used.
The CY2071A has one PLL and outputs three factory-EPROM
configurable clocks: CLKA, CLKB, and CLKC. The output
clocks can originate either from the PLL or the reference, or
selected dividers thereof. Additionally, pin 8 can be configured
to be an Output Enable or a Select input.
The CY2071A can replace multiple Metal Can Oscillators
(MCO) in a synchronous system, providing cost and board
space savings to the manufacturer. Hence, these devices are
ideally suited for applications that require multiple, accurate,
and stable clocks synthesized from low-cost generators in
small packages. A hard-disk drive is an example of such an
application. In this case, CLKA drives the PLL in the Read
Controller, while CLKB and CLKC drive the MCU and associ-
ated sequencers.
CyClocks Software
CyClocks is an easy-to-use software application that allows
you to configure any one of the EPROM-Programmable
Clocks offered by Cypress. You may specify the input frequen-
cy, PLL and output frequencies, and different functional op-
tions. Please note the output frequency ranges in this data
sheet when specifying them in CyClocks to ensure that you
stay within the limits. You can download a copy of CyClocks
free on the Cypress Semiconductor website at www.cy-
press.com.
Consider using the CY2081 for applications that require unre-
lated output frequencies. Consider using the CY2291,
CY2292, or CY2907 for applications that require more than
three output clocks.
Cypress FTG Programmer
The Cypress Frequency Timing Generator (FTG) Programmer
is a portable programmer designed to custom program our
family of EPROM
Field
Programmable Clock Devices. The
FTG programmers connect to a PC serial port and allow users
of CyClocks software to quickly and easily program any of the
CY2291F, CY2292F, CY2071AF, and CY2907F devices. The
ordering code for the Cypress FTG Programmer is CY3670.
