Texas Instruments CDCE72010

the cdce72010 is a high-performance low phase noise and low skew clock synchronizer that synchronizes a vcxo (voltage controlled crystal oscillator) or vco (voltage controlled oscillator) frequency to one of two reference clocks. the clock path is fully programmable providing the user with a high degree of flexibility. the following relationship applies to the dividers: frequency (vcxo_in or aux_in) / frequency (pri_ref or sec_ref) = (p*n)/(r*m) the vc(x)o_in clock operates up to 1.5ghz through the selection of external vc(x)o and loop filter components. the pll loop bandwidth and damping factor can be adjusted to meet different system requirements. the cdce72010 can lock to one of two reference clock inputs (pri_ref and sec_ref) and supports frequency hold-over mode for fail-safe and system redundancy. view all in datasheet
