8V49N211

Clock Generator for Broadcom Processor 8V49N211 DATA SHEET General Description The 8V49N211 is a high-performance PLL-based clock generator designed to interface with Broadcom XLP2xxx processors. The 8V49N211 has one 25MHz crystal input to generate output frequencies to support XLP Core/DDR3, USB, SGMII/XAUI and PCIe reference clocks in a single chip. The 8V49N211 low jitter VCO easily meets PCI Express Gen 1, 2 and 3 requirements. IDT’s Fourth Generation FemtoClock® NG technology has best in class phase noise performance. Features Fourth Generation FemtoClock® NG PLL technology Two LVCMOS clock outputs for core/DDR3 at 133.33MHz or 66.66MHz One LVDS clock output for USB at 100MHz Three LVDS clock outputs for SGMII/XAUI at 125MHz Five HCSL clock outputs for PCIe at 100MHz Crystal oscillator interface designed for 25MHz (CL = 12pF) frequency, IDT Part #603-25-173 PCI Express Gen 1 (2.5Gb/s), Gen 2 (5Gb/s) and Gen 3 (8Gb/s) jitter compliant Full 3.3V operating supply voltage Lead-free (RoHS 6) packaging -40°C to 85°C ambient operating temperature Pin Assignment V DDO_B QB0 nQB 0 VS S O_B QB1 nQB 1 V DDO_B QB2 nQB 2 VS S O_B VS S O_C5 QC5 nQC 5 V DDO_C 5 G ND VS S O_A QA1 QA0 V DDO_A FSEL BYPAS S V DD G ND OE _1 OE _2 OE _3 OE _4 G ND 42 41 40 39 38 37 36 35 34 33 32 31 30 29 43 28 44 27 45 26 46 25 47 24 48 49 8V49N211 50 23 22 21 51 20 52 19 53 18 54 17 55 16 56 15 1 2 3 4 5 6 7 8 9 10 11 12 13 14 V DDO_C nQC 4 QC4 nQC 3 QC3 VS S O_C nQC 2 ...
