DATASHEET
General Description
The IDT8N4D085 is an LVDS Dual Frequency-Programmable Crys-
tal Oscillator with very flexible frequency programming capabilities.
The device uses IDT’s fourth generation FemtoClock
®
NG technolo-
gy for an optimum of high clock frequency and low phase noise per-
formance. The device accepts 2.5V or 3.3V supply and is packaged
in a small, lead-free (RoHS 6) 6-lead ceramic 5mm x 7mm x 1.55mm
package.
The device can be programmed to any in the range from 15.476MHz
to 866.67MHz and from 975MHz to 1,300MHz and supports a very
high degree of frequency precision of 218Hz or better. One of two
pre-set output frequencies is selected by the FSEL pin.The extended
temperature range supports wireless infrastructure, telecommunica-
tion and networking end equipment requirements.

Why can't the kernel be started if there are bad blocks in the kernel burning area?
[table=98%,rgb(239, 245, 249)] [tr][td]Hi everyone, the address I burned the kernel to is 0x200000, but there is a bad block at 0x280000. When I boot, it prompts bad CRC and cannot find the kernel. I ...
