General Description
The CY22180 is a low jitter clock generator for use in
networking,
telecommunication,
electronics, and other general purpose applications. The
CY22180 offers a single programmable output and an optional
copy of the input frequency. The on-chip reference oscillator is
designed to run off a 10–30 MHz crystal, or a 10–133 MHz
external clock signal. The output frequency range is 20–200
MHz. The CY22180 comes in an 8-pin SOIC, and requires a
3.3V power supply.

Programming Description
Field Programmable (CY22180FSXC and CY22180FSXI)
The CY22180 is programmed at the package level, that is, in
a programmer socket. The CY22180 is flash technology
based, so the parts can be reprogrammed up to 100 times.
This enables fast and easy design changes and product
updates, and eliminates any issues with old and out-of-date
inventory.
Samples and small prototype quantities can be programmed
on the CY3672 programmer with the CY3619 socket adapter.

Online Software
CyberClocks Online Software is a web-based software appli-
cation that allows the user to custom-configure the CY22180.
All the parameters in
Table 1
given as “Enter Data” can be
programmed into the CY22180. CyberClocks Online outputs
an industry-standard JEDEC file used for programming the
CY22180.

CY3672-USB Programming Kit and CY3619 Socket
Adapter
The Cypress CY3672 FTG programmer and CY3619 socket
adapter are needed to program the CY22180. The socket
adapter comes with small prototype quantities of CY22180.
The CY3619 can be ordered separately, so existing users of
the CY3672-USB programmer need order only the socket
adapters to program the CY22180.
Factory Programmed CY22180
Factory programming is available for volume manufacturing by
Cypress. All requests must be submitted to the local Cypress
Field Application Engineer (FAE) or sales representative.
Once the request has been processed, you will receive a new
part number (dash number) and samples with the
programmed values. This part number will be used for
additional sample requests and production orders.
Additional information on the CY22180 can be obtained from
the Cypress website at

Crystal input or reference clock input.
3.3V power supply.
Power down pin, active LOW. If PD# = 0, the PLL and oscillator are powered down
and outputs are weakly pulled low.
Output enable pin, active HIGH. If OE = 1, CLKOUT and REFOUT are enabled.
User has the option of choosing either PD# or OE function.
Power supply ground.
Buffered reference output.
Low jitter clock output.
No connect. Leave this pin floating.
Crystal output. Leave this pin floating if external clock is used.
