APPLICATIONS Low jitter, low phase noise clock distribution Clocking high speed ADCs, DACs, DDSs, DDCs, DUCs, MxFEs Defense and aerospace applications GENERAL DESCRIPTION The AD9512-EP provides a multi-output clock distribution in a design that emphasizes low jitter and low phase noise to maximize data converter performance. Other applications with demanding phase noise and jitter requirements can also benefit from this part. There are five independent clock outputs. Three outputs are LVPECL (1.2 GHz), and two are selectable as either LVDS (800 MHz) or CMOS (250 MHz) levels. Each output has a programmable divider that can be bypassed or set to divide by any integer up to 32. The phase of one clock output relative to another clock output can be varied by means of a divider phase select function that serves as a coarse timing adjustment. The AD9512-EP is ideally suited for data converter clocking applications where maximum converter performance is achieved by encode signals with subpicosecond jitter. The AD9512-EP is available in a 48-lead LFCSP and can be operated from a single 3.3 V supply. The temperature range is −55°C to +85°C. Additional application and technical information can be found in the AD9512 data sheet. Note that the delay block element that exists in Channel 4 of the AD9512 standard product is not supported in this AD9512-EP version.
