CDCE937PWR

The CDCE937PWR from Texas Instruments is a versatile clock generator and PLL synthesizer designed for applications requiring highly accurate clock signals. This device features three Phase-Locked Loops (PLLs) and a Voltage-Controlled Crystal Oscillator (VCXO) for flexible frequency generation.

Key electrical specifications include up to 7 LVCMOS outputs, a maximum output frequency of 230MHz, and a core supply voltage of 1.8V with output supply voltages of 2.5V or 3.3V. It supports both LVCMOS and XTAL input types. The device offers features such as integrated EEPROM for nonvolatile storage of settings, multiplier/divider functions, and spread-spectrum clocking (SSC) for EMI reduction.

Packaged in a 20-TSSOP, the CDCE937PWR is suitable for surface mount applications. Its wide operating temperature range of -40°C to 85°C makes it robust for various environmental conditions. The integrated PLL core is designed for low noise and low period jitter, typically 60ps. Flexible control inputs allow for SSC selection, frequency switching, output enable, or power down functions, making it adaptable for video, audio, USB, and wireless communication systems.

This clock synthesizer is part of Texas Instruments' Programmable Clock Generator family, offering in-system programmability and nonvolatile EEPROM storage for customer settings. It generates common clock frequencies used with TI DaVinci, OMAP, and DSP processors.
