VCXO-Based Frame Clock Frequency TranslatorThe MK2059-01 is a VCXO (Voltage Controlled Crystal Oscillator) based Clock Generator that produces common telecommunications reference frequencies. The output Clock is phase locked to an 8kHz (frame rate) input reference Clock The MK2059-01 also provides jitter attenuation. Included in the selection of output frequencies are these common system clocks:
1.544 MHz (T1)
2.048 (E1)
19.44 MHz (OC-3)
16.384 MHz (8x E1)
This monolithic IC, combined with an external inexpensive quartz crystal, CAN be used to replace a more costly hybrid VCXO retiming module. Through selection of external loop Filter components, the PLL loop bandwidth and damping factor CAN be tailored to meet input Clock jitter attenuation requirements. A loop bandwidth down to the Hz range is possible.
Generates T1, E1, OC-3 and other common telecom Clock frequencies from an 8 kHz frame Clock
