CY5057
High-Frequency Flash Programmable
PLL Die with Spread Spectrum
Features
Flash programmable die for in-package programming of crystal
oscillators
High resolution phase-locked loop (PLL) with 10-bit multiplier
and 7-bit divider
Flash programmable capacitor tuning array
Simple 2-pin programming interface (excluding VDD and VSS
pins)
On-chip oscillator used with external 25.1 MHz fundamental
tuned crystal
Flash programmable spread spectrum with spread
percentages between +0.25% and +2.00%
Spread spectrum on/off function
Operating frequency
5 to 170 MHz at 3.3V ± 10%
Seven-bit linear post divider with divide options from
divide-by-2 to divide-by-127
Programmable PD# or OE pin
Programmable asynchronous or synchronous OE and PD#
modes
Low jitter output
< 200 ps (pk-pk) at 3.3V ± 10%
Controlled rise and fall times and output slew rate
Software configuration support
Benefits
Enables quick turnaround of custom oscillators and lowers
inventory costs through stocking blank parts. In addition, the
part may be Flash programmed up to 100 times. This reduces
programming errors and provides an easy upgrade path for
existing designs.
Enables synthesis of highly accurate and stable output clock
frequencies with zero or low PPM.
Enables fine tuning of output clock frequency by adjusting the
CLoad of the crystal.
Allows the device to go into standard 4 or 6-pin packages.
Lowers cost of oscillator, because PLL may be programmed to
a high frequency using a low frequency, low cost crystal.
Provides various spread percentage.
Provides the ability to enable or disable spread spectrum with
an external pin.
Provides flexibility in output configurations and testing.
Enables low operation or output enable function.
Provides flexibility for system applications through selectable
instantaneous or synchronous change in outputs.
Suitable for most PC, consumer, and networking applications.
Has lower EMI than oscillators.
Easy to use software support for design entry.

Flash programmable to function as power down or output enable
in normal operating mode. Weak pull up is enabled by default
Super voltage when going into programming mode
Data pin when going into and when in programming mode
10 Active low spread spectrum control. Asserting LOW turns the
internal modulation waveform on. Strong pull down is enabled by
default. Pull down is disabled in power down mode
Clock pin in programming mode. Must be double bonded to the
OUT pad for pinouts not using the SSON# function. There is an
internal pull down resistor on this pad
9 Clock output. There is an internal pull down resistor on this pad.
Weak pull down is enabled by default. Default output is from the
reference
