The AD9530 is a fully integrated PLL and distribution supporting, clock cleanup, and frequency translation device for 40 Gbps/ 100 Gbps OTN applications. The internal PLL can lock to one of two reference frequencies to generate four discrete output frequencies up to 2.7 GHz. The AD9530 features an internal 5.11 GHz to 5.4 GHz, ultralow noise voltage controlled oscillator (VCO). All four outputs are individually divided down from the internal VCO using two high speed VCO dividers (the Mx dividers) and four individual 8-bit channel dividers (the Dx dividers). The high speed VCO dividers offer fixed divisions of 2, 2.5, 3, and 3.5 for wide coverage of possible output frequencies. The AD9530 is configurable for loop bandwidths <15 kHz to attenuate reference noise. The AD9530 is available in a 48-lead LFCSP and operates from a single 2.5 V typical supply voltage. The AD9530 operates over the extended industrial temperature range of −40°C to +85°C.
