Texas Instruments CDCM6208V2G Low Jitter Clock Generator
Texas Instruments CDCM6208V2G Low Jitter Clock Generator is a highly versatile, low jitter, low power frequency synthesizer that can generate eight low-jitter clock outputs. This device is selectable between LVPECL-like high-swing CML, normal-swing CML, LVDS-like low-power CML, HCSL, or LVCMOS, from one of two inputs. The CMCD6208V2G can feature a low-frequency crystal or CML, LVPECL, LVDS, or LVCMOS signals for various wireless applications. This device also features an innovative fractional divider architecture for four outputs that can generate any frequency with better than 1ppm frequency accuracy. The Texas Instruments CDCM6208V2G can be easily configured through 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
