ESCRIPTION
The ICS8432-51 is a general purpose, dual output
Crystal-to-3.3V Differential LVPECL High Fre-
HiPerClockS™
quency Synthesizer and a member of the
HiPerClockS™ family of High Performance Clock
Solutions from IDT. The ICS8432-51 has a select-
able REF_CLK or crystal input. The VCO operates at a fre-
quency range of 250MHz to 700MHz. The VCO frequency is
programmed in steps equal to the value of the input reference
or crystal frequency. The VCO and output frequency can be
programmed using the serial or parallel interface to the con-
figuration logic. The low phase noise characteristics of the
ICS8432-51 make it an ideal clock source for Gigabit Ethernet,
Fibre Channel 1 and 2, and Infiniband applications.

When I do thermal transfer printing on a PCB myself, if I don't have a thermal transfer machine, can I use a large iron block to press down the thermal transfer paper and blow it with a hot air gun?
As the title says, since I don't have a thermal transfer printer, I only have a heat gun. After watching the thermal transfer process, I think it should be possible....
