IDT, Integrated Device Technology Inc 82V3012PVG

Description
The IDT82V3012 is a Stratum 3, Stratum 4 Enhanced, and Stratum 4 timing WAN PLL for DS1, E1, and OC3 interfaces. It supports AT&T TR62411 and Telcordia GR-1244-CORE timing standards. The device accepts two independent reference inputs with the same or different nominal frequencies. It provides C1.50, C30, C20, C40, C60, C80, C160, C190, and C320 output clock signals, as well as seven types of 8 kHz framing pulses. The IDT82V3012 also features a C2/C1.5 output clock signal with frequency controlled by the selected reference input, holdover frequency accuracy of 0.025 ppm, phase slope of 5 ns per 125 μs, wander attenuation from 2.1 Hz, fast lock mode, Time Interval Error (TIE) correction, MTIE of 600 ns, JTAG boundary scan, holdover status indication, freerun status indication, normal status indication, lock status indication, and input reference quality indication.
