描述
The 8T49N028 is a low RMS phase jitter clock synthesizer with selectable internal crystal oscillator or external clock references and eight outputs, configurable as either LVDS, LVPECL, or high impedance.
After power up, two frequency select pins determine one of up to four different sets of factory preprogrammed crystal or input frequency and output frequency configurations. From a single input reference, as many as three different output frequencies may be selected for the output banks: two of these frequencies can be generated by the internal crystal oscillator, and/or external clock pre-divider, and/or A output divider, and/or B output divider. The third output frequency is from the B output divider. Device pre-programming can be overwritten through the provided I2C interface.
The specific internal register settings for each of the four frequency sets are specified by a Renesas order code. Custom codes can be provided by contacting Renesas.
