VCXO-Based Universal Clock Translator

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 Input Clock frequency <1 kHz to 170 MHz Output Clock frequency of 500 kHz to 160 MHz Clock translation examples: T1 (1.544 MHz) to/from E1 (2.048 MHz) T3 (44.736 MHz) to/from E3 (34.368 MHz) OC-3 (155.52 MHz) to/from T1 (1.544 MHz) CCIR-601 (27 MHz) to/from SMPTE 274M (74.125 MHz) Jitter attenuation of input Clock provided by VCXO circuit. Jitter transfer characteristics user configured through external loop Filter component selection. Low jitter and phase noise generation PLL lock status output PLL Clear function allows seamless synchronizing to an altered input Clock phase 2nd PLL provides frequency translation of VCXO PLL output (VCLK) to a higher or alternate output frequency (TCLK) Device will free-run in the absence of an input Clock based on VCXO frequency 56-pin TSSOP package Available in Pb (lead) free package Single 3.3 V power supply 5 V tolerant Clock input By Integrated Device Technology
