The module comprises a plurality of housings for mounting a variety of crystal oscillators.
Real Time Clock controlled through I2C with battery backup. The accuracy of the order of 20 ppm.
Multiple division ratios can be selected by jumpers. Possible division ratios are: (÷1, ÷2, ÷4, ÷8) or (÷2, ÷4, ÷8, ÷16) every output is synchronous each other. The common enable (EN) is synchronous so that the internal dividers will only be enabled/disabled when the internal clock is already in the LOW state.
PLL clock generator with Texas Instruments chip CDCE913. Contains VCXO with external xtal andone internal PLL. It has three LVCMOS outputs with individual frequency dividers capable togenerate ut to 230MHz clocks. The chip is programmable via I2C and configuration may be savedto internal EEPROM.
