The MK2069-04 is a VCXO (Voltage Controlled Crystal Oscillator) based clock generator that features a PLL (Phase-Locked Loop) input reference divider and feedback divider that have a wide numeric range selectable by the user. This enables a complex PLL multiplication ratio that can be used for translation between clock frequency standards. The on-chip VCXO produces a stable, low jitter output clock using a phase detector frequency down to 8 kHz or lower. This means the MK2069-04 can translate between clock frequencies that have a low common denominator, such as the 8 kHz frame clock common with telecom standards. The MK2069-04 also provides jitter attenuation of the input clock and can accept a low input frequency as well. The device is optimized for user configurability by providing access to all major PLL divider functions. No power-up programming is needed as configuration is pin selected. External VCXO loop filter components provide an additional level of user configurability. The MK2069-04 includes a lock detector (LD) output that serves as a clock status monitor. The clear (CLR) input enables rapid synchronization to the phase of a newly selected input clock.
