Texas Instruments CDCM6208 2:8 Clock Generator & Jitter Cleaner

Texas Instruments CDCM6208 2:8 Clock Generator and Jitter Cleaner is a highly versatile, low jitter, low power frequency synthesizer. The device generates eight low jitter clock outputs, selectable between LVPECL-like high-swing CML, normal-swing CML, LVDS-like low-power CML, HCSL, or LVCMOS. It includes one of two inputs that can feature a low-frequency crystal or CML, LVPECL, LVDS, or LVCMOS signals. These can be used for various wireless infrastructure baseband, wireline data communication, computing, low power medical imaging, and portable test/measurement applications. The CDCM6208 also features an innovative fractional divider architecture for four outputs that generate any frequency with better than 1ppm accuracy. The CDCM6208 can be easily configured through an I2C or SPI programming interface. Pin mode is also available in the absence of a serial interface that can set the device in 1 of 32 distinct pre-programmed configurations using control pins.

Features

  • Superior performance with low power
    • Low noise synthesizer (265fs-rms typical Jitter) or low noise Jitter cleaner (1.6ps-rms typical Jitter)
    • 0.5W typical power consumption
    • High channel-to-channel isolation and excellent PSRR
    • Customizable device performance through flexible 1.8V, 2.5V, and 3.3V power supplies allowing mixed output voltages
