CY22800
General Description
VCXO
The CY22800 is a multi-function clock generator that supports
various applications in consumer and communications markets.
The device uses the Cypress proprietary PLL along with Spread
Spectrum and VCXO technology to make it one of the most
versatile clock synthesizers in the marketplace. The CY22800 is
a field-programmable synthesizer that can be programmed using
an easy-to-use programmer dongle, CY36800, with one of many
predefined configuration files for fast sample generation of
prototype builds. The CY22800 is a reprogrammable device that
can be programmed up to 100 times. The latest configurations
available for this device are summarized in Table 2.
One of the key components of the CY22800 device is the VCXO.
The VCXO is used to “pull” the reference crystal higher or lower
in order to lock the system frequency to an external source. This
is ideal for applications where the output frequency needs to
track along with an external reference frequency that is
constantly shifting.
The CY22800 can generate Spread Spectrum Clocks (SSCG) to
reduce EMI found in today’s high-speed digital electronic
systems.
The device uses proprietary Spread Spectrum Clock (SSC)
technology to synthesize and modulate the frequency of the
input clock. By modulating the frequency of the clock, the
measured EMI at the fundamental and harmonic frequencies is
greatly reduced. This reduction in radiated energy can significantly reduce the cost of complying with regulatory agency
(EMC) requirements and improve time to market without
degrading system performance.
The CY22800 uses a preprogrammed configuration of memory
arrays to synthesize output frequency and offers eight different
spread percentages (refer to Table 2 – Code numbers -015 to
-022), and an additional option to turn the spread on and off.
VCXO Profile
Figure 2 shows an example of what a VCXO profile looks like.
The analog voltage input is on the X-axis and the PPM range is
on the Y-axis. An increase in the VCXO input voltage results in a
corresponding increase in the output frequency. This has the
effect of moving the PPM from a negative to positive offset.
