sy nce clock generation; and general purpose fr equency translation. the device supports physi cal layer timing with digital plls (dplls) and it supports packet based timing with digitally controlled o scillators (dcos). input-to- input, input-t o-output and output-to- output phase skew can all be precisely managed. the device outputs low-jitter clocks that can directly synchronize ethernet int erfaces; as well as sonet/sdh and pdh interfaces and i eee 1588 time stamp units (tsus). the 82p33810 accepts six differential reference inputs and six si ngle ended reference inputs that can operate at common gnss, e thernet, sonet/sdh and pdh frequencies that range in frequency from 1 pulse per second (pps) to 650 mhz. the device also provides two al ternate mark inversion (ami) inputs for composite clock (cc) signals bearing 64 khz, 8 khz and 0.4 khz synchr onization information. the refe rences are continu- ally monitored for loss of signal and for frequency offset per user programmed threshol ds. all of the references are available to all three dplls. the active reference for each dpll is determined by forced selecti on or by automatic selection bas ed on user programmed priorities and locking allow- ances and based on the reference monitors and los inputs. the 82p33810 can accept a clock reference and an associated phase locked sync signal as a pair. dpll1 or dpll2 can lock to the clock refer- ence and align the frame sync and multi-frame sync outputs with t he paired sync input. the device allows any of the differentia l or single ended refer- ence inputs to be configured as sync inputs that can be associat ed with any of the other diffe rential or single ended reference inputs. the input sync signals can have a frequency of 1 pps, 2 khz, 4 khz or 8 khz. th is feature enables dpll1 or dpll2 to phase align its frame sync and multi-frame sync outputs with a sync input without the need use a low bandwidth setting to lock directly to the sync input. dpll1 and dpll2 support four primary operating m odes: free-run, locked, holdover and dco. in free-run mode the dplls synthesize clocks based on the system clock alone. in locked mode the dplls filter reference clock jitter with t he selected bandwidth. in locked mode, the long-term output frequency accuracy is the same as the long term frequency accu racy of the selected input reference. in holdover mode, th e dpll uses fre- quency data acquired while in locked mode to generate accurate freque ncies when input references ar e not available. in dco mode the dpll con- trol loop is opened and the dco can be controlled by a ptp clock re covery servo running on an exter nal processor to synthesize ptp clocks. the 82p33810 requires a system clock for its re ference monitors and other digital circuitry. the fr equency accuracy of the syst em clock deter- mines the frequency accuracy of the dplls in free-run mode. the frequency stability of the system clock determines the frequenc y stability of the dplls in free-run mode and in holdover mode; and it affect s the wander generation of the dplls in locked and dco modes. when used with a suitable system clock, dpll1 and dpll2 meet the frequency accuracy, pull-in, hold-in, pull-out, noise generati on, noise toler- ance, transient response, and holdover per formance requirements of the following applications: itu-t g.8262/g.813 eec/sec optio ns 1 and 2, itu- t g.8263, itu-t g.8273.2, telcordia gr-1244 stratum 3 (s3), telcor dia gr-253-core stratum 3 (s3) and sonet minimum clock (smc). dpll1 and dpll2 can be configured with a range of selectable filt ering bandwidths from 0.09 mhz to 567 hz. the 17 mhz bandwidth can be used to lock the dpll directly to a 1 pps reference. the 69 mhz and the 92 mhz bandwidths can be used for g.8273.2. the 92 mhz bandwidth can be used for g.8262/g.813 option 2 or telcordia gr-253-core s3 or smc applications. the bandwidths in the range 1.1 hz to 8.9 hz can be used for g.8262/g.813 option 1 applications. bandwidths above 10 hz can be used in jitter attenuation and rate conversion applicatio ns. dpll1 and dpll2 are each connected to time of da y (tod) counters or time accumulators; t hese tod counters/time accumulators can be used to track differences between the two time domains and to time-stamp external event s by using reference inputs as triggers. dpll3 supports three primary oper ation modes: free-run, locked and holdover. dpll3 is a wideband (bw > 25hz) frequency translat or that can be used, for example, to convert a recovered line clock to a 1.544 mhz or 2.048 mhz synchr onization interface clock. in telecom boundary clock (t-bc) and telecom time slave clock (t-tsc) applications per itu-t g.8275.2, dpll1 and dpll2 are both used; one dpll is configured as a dco to synthesize ptp clocks and the other dpll is configured as an eec/sec to generate physical la yer clocks. combo mode provides physical layer frequency s upport from the eec/sec to the ptp clock.

9 ?2016 integrated device technology, inc. 82p33810 short form datasheet revision 6, march 29, 2016 2.1 recommendations for unused input and output pins 2.1.1 inputs control pins all control pins have internal pul l-ups or pull-downs ; additional resis- tance is not required but can be added for additional protection. a 1k resistor can be used. single-ended clock inputs for protection, unused single- ended clock inputs should be tied to ground. differential clock inputs for applications not requiring the use of a differential input, both *_pos and *_neg can be left floating. though not required, but for additional protection, a 1k resistor can be tied from _pos to ground. 2.1.2 outputs status pins for applications not requiring the use of a status pin, we recommend bringing out to a test point for debugging purposes. single-ended clock outputs all unused single-ended clock outputs can be left floating, or can be brought out to a test point for debugging purposes. differential clock outputs all unused differential outputs can be left floating. we recommend that there is no trace attached. both sides of the differential output pair should either be left floating or terminated.
