8.3.2 Device Block-Level Description

The device contains a BAW oscillator, frequency integer divider, and CMOS driver which together generates a pre-programmed output frequency. Temperature variations of oscillation frequency are continuously monitored by internal precision temperature sensor and provided as input to the frequency control logic block. Using this Frequency Control Logic block, frequency corrections are performed internally for maintaining the output frequency within ±25ppm across temperature range and aging. The device contains an internal LDO which reduces the power supply noise, resulting in low noise clock output.
