Texas Instruments  CDCM6208V2GRGZR

The CDCM6208V2G is a highly versatile, low jitter, low-power frequency synthesizer that can generate eight low jitter clock outputs, selectable between LVPECL-like high-swing CML, normal-swing CML, LVDS-like low-power CML, HCSL, or LVCMOS, from one of two inputs that can feature a low frequency crystal or CML, LVPECL, LVDS, or LVCMOS signals for a variety of wireless infrastructure baseband, wireline data communication, computing, low power medical imaging and portable test and measurement applications. The CDCM6208V2G also features an innovative fractional divider architecture for four of its outputs that can generate any frequency with better than 1ppm frequency accuracy. The CDCM6208V2G can be easily configured through I2C or SPI programming interface and in the absence of serial interface, pin mode is also available that can set the device in 1 of 32 distinct pre-programmed configurations using control pins.

In synthesizer mode, the overall output jitter performance is less than 0.5 ps-rms (10 k – 20 MHz) or 20 ps-pp (unbound) on output using integer dividers and is between 50 to 220 ps-pp (10 k – 40 MHz) on outputs using fractional dividers depending on the prescaler output frequency.

In jitter cleaner mode, the overall output jitter is less than 2.1 ps-rms (10 k – 20 MHz) or 40 ps-pp on output using integer dividers and is less than 70 ps to 240 ps-pp on outputs using fractional dividers. The CDCM6208V2G is packaged in a small 48-pin 7 mm × 7 mm QFN package.
