clo c k generators - s m t 10 HMC1031MS8E v00.0312 clock generator with integer-n pll 0.1 - 500 mhz HMC1031MS8E application information figure 15. HMC1031MS8E application diagram jitter attenuation in some cases, reference clocks to the system may come from external noisy sources with high jitter. t he hmc1031m s 8 e may be used to attenuate this incoming jitter and distribute a clean clock in the system. in such a scheme, a narrow loop flter is selected for the hmc1031m s 8 e . t he device frequency locks to the external vcx o but the reference jitter is attenuated as defned by the set loop flter bandwidth. t he fnal output frequency and phase noise characteristics outside the loop bandwidth is defned by the phase noise characteristics of the vcx o used. a low jitter clock reference yields better clocking performance, better lo performance of r f p ll vc o s, and improves the snr performance of data converters ( a dc/d a c). frequency translation quite often, the reference clock in a t est & measurement or a communications system is a high accuracy o cx o ( o ven controlled crystal o scillator) with excellent long-term stability. t he hmc1031m s 8 e may fnd applications when the o cx o frequency needs to be multiplied up to a higher rate to drive the primary clock inputs in a system. t he device offers a very low power, small package and high performance method to multiply its incoming frequency in x1, x5 and x10 rates. s uch multiplication is needed because the higher reference clocks improve phase n oise, a dc/d a c snr, clock generator jitter and phy bers. in this scheme, the HMC1031MS8E may be connected to an external low cost vcx o (e.g. at 50mhz or 100mhz), and lock this external vcx o to the excellent long-term stability of the o cx o . loop bandwidths with HMC1031MS8E in typical jitter attenuation applications, an incoming reference clock is frequency locked with a narrow p ll l oop bandwidth such that its incoming noise is fltered out by the pll and vcxo combination. the out of band phase noise of the p ll follows the vcx o that its locked to. a narrow p ll loop bandwidth ensures that the output jitter is determined by the vcx o (or any other type of high quality factor vc o ) and not affected by the spectral noise of the incoming clock beyond the set loop bandwidth. considering that the hmc1031m s 8 e will be used in narrow loop flter bandwidth confgurations, the device is designed to have a low charge pump current of 50u a . t his architecture offers advantages in low power consumption and loop flter design. t ypically, narrow loop flter bandwidths require large flter capacitors. t hanks to the low charge pump current design of the hmc1031m s 8 e , smaller loop flter capacitor sizes may be used to implement narrow loop flters. it should be kept in mind that the hmc1031m s 8 e is designed to operate in only a few khz loop bandwidths in its widest-loop bandwidth confguration. using vco/vcxos with negative tuning slope in its normal confguration, hmc1031m s 8 e will work with any vc o /vcx o that has a positive tuning slope. for any vc o /vcx o with negative tuning slope i.e where frequency decreases with increasing tuning voltage, the loop flter a c ground should be connected to vcc instead of g n d. for price, delivery and to place orders: hittite microwave corporation, 2 elizabeth drive, chelmsford, ma 01824 phone: 978-250-3343 fax: 978-250-3373 order on-line at www.hittite.com application support: phone: 978-250-3343 or apps@hittite.com
