MoBL® UniClock CY22M1
Single Output, Low Power Programmable Clock
Generator for Portable Applications
Features
■ Small Footprint, 8-Pin QFN 1.7 x 1.7 x 0.6 mm3 Package
■ Low Power and Low Jitter Operation
■ Multiple Operating Voltages:
❐ CY22M1S: 2.5V, 3.0V, or 3.3V
❐ CY22M1L: 1.8V
■ Programmable Single Output Clock Generator Frequency
Range:
❐ 1 to 80 MHz
■ Crystal or External Reference Clock Input Frequency Range:
❐ Fundamental Tuned Crystal: 8 to 48 MHz
❐ External Reference Clock: 1 to 80 MHz
■ Programmable Capacitor Tuning Array
■ Programmable PD# or OE Control Pin
■ Programmable Asynchronous or Synchronous OE and PD#
Modes
■ Programmable Output Buffer Drive Strength
Benefits
■ Services handsets, portable media players, personal
navigation devices, digital cameras, digital camcorders, and
other portable applications.
■ Saves PCB space due to small form factor.
■ Enables quick turnaround as well as flexibility and adaptability
to design changes through programmability.
■ Enables synthesis of highly accurate and stable output clock
frequencies with zero or low PPM error.
■ Enables fine tuning of output clock frequency by adjusting the
crystal load CLoad using programmable internal capacitors.
■ Lowers clock solution cost by pairing a high frequency PLL
programmability with a low cost, low frequency crystal.
■ Enables low power during the power down or output disable
function.
■ Provides flexibility for system applications through selectable
asynchronous or synchronous output enable and disable.
