Data Sheet 0.1 MHz to 500 MHz Clock Generator with Integer N PLL HMC1031 FEATURES Low current consumption: 1.95 mA typical High phase frequency detector rate: 140 MHz Hardware pin-programmable clock multiplication ratios: 1×/5×/10× Lock detect indicator Power-down mode (0.8 μA typical) 8-lead MSOP package: 4.9 mm × 3.0 mm APPLICATIONS Low jitter clock generation Low bandwidth (BW) jitter attenuation Low frequency phase-locked loops (PLLs) Frequency translation Oven controlled crystal oscillator (OCXO) frequency multipliers Phase lock clean high frequency references to 10 MHz equipment GENERAL DESCRIPTION Together with an external loop filter and a voltage controlled crystal oscillator (VCXO), the HMC1031 forms a complete clock generator solution targeted at low frequency jitter attenuation and reference clock generation applications. The HMC1031 features a low power integer N divider, support- ing divide ratios of 1, 5, and 10, which is controlled via external hardware pins and requires no serial port. FUNCTIONAL BLOCK DIAGRAM VCC 1 REFIN 2 HMC1031 PFD/CP 8 GND 7 CP LKDOP 3 D0 4 LKD 1/N Figure 1. 6 VCOIN 5 D1 The integrated phase detector and charge pump are capable of operating at up to 140 MHz, and a maximum VCXO input of 500 MHz ensures frequency compliance with a wide variety of system clocks and VCXOs. Additional features include an integrated lock detect indicator available on a dedicated hardware pin, and a built in power- down mode. The HMC1031 is housed in an 8-lead MSOP package. Rev.

Rev. C \| Page 5 of 13 5 Page Data Sheet For example, to guarantee correct lock detector operation with a 10 MHz reference (tPD = 100 ns) and no leakage into the VCO VTUNE pin, the total capacitor leakage must be less than 1.5 µA. A typical MLCC 33 nF, 25 V loop filter capacitor has approxi- mately 0.5 nA of leakage (Murata GRM155R71E333KA88). HMC1031 PRINTED CIRCUIT BOARD (PCB) Use a sufficient number of via holes to connect the top and bottom ground planes (see Figure 23).
