DESCRIPTION

· The CDCE925 and CDCEL925 are modular PLL-based, low-cost, high-performance, programmable clock synthesizers, multipliers, and dividers.

· They generate up to five output clocks from a single input frequency, with each output programmable in-system for any clock frequency up to 230MHz using up to two independent configurable PLLs.

· The devices feature a separate output supply pin, VDDOUT, which is 1.8V for CDCEL925 and 2.5V to 3.3V for CDCE925.

· The input accepts an external crystal or LVCMOS clock signal, with an on-chip load capacitor adequate for most applications, programmable from 0 to 20pF.

· An on-chip VCXO is selectable, allowing synchronization of the output frequency to an external control signal, such as a PWM signal.

FEATURES

· Member of the Programmable Clock Generator Family, offering various PLL and output configurations.

· In-System Programmability and EEPROM for storing customer settings.

· Flexible Input Clocking Concept with options for external crystal or LVCMOS clock signal.

· Low-Noise PLL Core with integrated loop filter components and low period jitter (typical 60ps).

· Separate Output Supply Pins for different voltage requirements.

· Flexible Clock Driver with user-definable control inputs for various functionalities.

· Wide Temperature Range: -40°C to 85°C.

· Packaged in TSSOP with a development and programming kit available for easy PLL design and programming.

APPLICATIONS

· Suitable for D-TVs, STBs, IP-STBs, DVD Players, DVD Recorders, and Printers.

· Generates highly accurate clocks for Video, Audio, USB, IEEE1394, RFID, Bluetooth®, WLAN, Ethernet™, and GPS.

· Generates common clock frequencies used with TI-DaVinci™, OMAP™, DSPs.
