Clock Generator 48-Pin VQFN EP T/R

The CDCM6208 is a highly versatile, low jitter low power frequency synthesizer which 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 CDCM6208 also features an innovative fractional divider architecture for four of its outputs that can generate any frequency with better than 1ppm frequency accuracy. The CDCM6208 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. 

Superior Performance with Low Power:

• Low Noise Synthesizer (265 fs-rms Typical Jitter)
  or Low Noise Jitter Cleaner (1.6 ps-rms Typical Jitter)
• 0.5 W Typical Power Consumption
• High Channel-to-Channel Isolation and Excellent PSRR
• Device Performance Customizable Through Flexible 1.8 V,
  2.5 V and 3.3 VPower Supplies, Allowing Mixed Output Voltages

Flexible Frequency Planning:

• 4x Integer Down-divided Differential Clock Outputs
  Supporting LVPECL-like, CML, or LVDS-like Signaling
• 4x Fractional or Integer Divided Differential Clock Outputs
  Supporting HCSL, LVDS-like Signaling, or Eight CMOS Outputs
