It has a selectable System CCB clock and a 66.66MHz DDRCLK. The IDT6V49205A also provides LP-HCSL PCIe outputs for low power and reduced board space. Output Features • 1 - Sys_CCB 3.3V LVCMOS output @ 100M/83.33M/ 80M/66.66M • 1 - DDRCLK 3.3V LVCMOS output @ 66.66M • 1 - 125M 3.3V LVCMOS output • 6 - LP-HCSL PCIe pairs selectable @ 100M or 125M • 6 - 25MHz 3.3V LVCMOS outputs • 2 - 2.048M 3.3V LVCMOS outputs • 2 - USB 3.3V LVCMOS outputs @12M or 24M Key Specifications • PCIe Gen1-2-3 compliant • <3p rms phase noise on REF outputs Recommended Application System Clock for Freescale P10xx and P20xx-based designs Features • Replaces 11 crystals, 2 oscillators and 3 clock generators; lowers cost, power and area • LP-HCSL PCIe outputs reduce termination resistors by 50% while saving 67% power; reduces board area and power • Industrial temperature range operation; supports demanding environmental conditions • Advanced 3.3V CMOS process; high-performance, low-power • Supports independent spread spectrum on Sys_CCB/DDRCLK and PCIe outputs • Packaged as 48-pin TSSOP or 48-pin 7x7mm VFQFPN with 0.5mm pad pitch;– Pb-free, RoHS compliant Block Diagram SCLK SDATA ^FS0 ^FS1 ^SELPCIE125#_100 X1 25MHz Crystal X2 Control Logic Crystal Oscillator PLL1 (SS) PLL4 (SS) PLL3 (non- SS) PLL2 (non- SS) 100MHz GND Sys_CCB 66M_SS PCIe_LR(5:0) USB_CLK(2:1) 2.048M(1:0) 125M REF(5:0) IDT® FREESCALE P10XX AND P20XX SYSTEM CLOCK W/66.66M DDR CLOCK 1 IDT6V49205A REV M 021214 1 page IDT6V49205A FREESCALE P10XX AND P20XX SYSTEM CLOCK W/66.66M DDR CLOCK Absolute Maximum Ratings Stresses above the ratings listed below can cause permanent damage to the IDT6V49205A. These ratings, which are standard values for IDT commercially rated parts, are stress ratings only. Functional operation of the device at these or any other conditions above those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods can affect product reliability. Electrical parameters are guaranteed only over the recommended operating temperature range.
