4 CML Output, Low Jitter Clock Generator with an Integrated 5.4 GHz VCO Data Sheet AD9530 FEATURES GENERAL DESCRIPTION Fully integrated, ultralow noise phase-locked loop (PLL) The AD9530 is a fully integrated PLL and distribution supporting, 4 differential, 2.7 GHz common-mode logic (CML) outputs clock cleanup, and frequency translation device for 40 Gbps/ 2 differential reference inputs with programmable internal 100 Gbps OTN applications. The internal PLL can lock to one termination options of two reference frequencies to generate four discrete output <232 fs rms absolute jitter (12 kHz to 20 MHz) with a non- frequencies up to 2.7 GHz. ideal reference and 8 kHz loop bandwidth The AD9530 features an internal 5.11 GHz to 5.4 GHz, ultralow <100 fs rms absolute jitter (12 kHz to 20 MHz) with an 80 kHz noise voltage controlled oscillator (VCO). All four outputs are loop bandwidth and low jitter input reference clock individually divided down from the internal VCO using two high Supports low loop bandwidths for jitter attenuation speed VCO dividers (the Mx dividers) and four individual 8-bit Manual switchover channel dividers (the Dx dividers). The high speed VCO dividers Single 2.5 V typical supply voltage offer fixed divisions of 2, 2.5, 3, and 3.5 for wide coverage of 48-lead, 7 mm 7 mm LFCSP possible output frequencies. The AD9530 is configurable for APPLICATIONS loop bandwidths <15 kHz to attenuate reference noise. 40 Gbps/100 Gbps optical transport network (OTN) line side The AD9530 is available in a 48-lead LFCSP and operates from a clocking single 2.5 V typical supply voltage. Clocking of high speed analog-to-digital converters (ADCs) The AD9530 operates over the extended industrial temperature and digital-to-analog converters (DACs) range of 40C to +85C.
