Hi, how do you generate clock signal with crystal?
could you point me to some online resources for generating clock signal with crystal? any part numbers?

Just use an inverter, a crystal and two capacitors. Most of the microcontrollers and DSPs on the market generate their clock signal that way. Attached is an application note from Microchip's Web site (AN588). It shows you the basic circuit, which uses an inverter internal to the microcontroller (figure 9), but you can implement this circuit using a discrete inverter. It works very well.
If you want you can also use a transistor based circuit but that is more complicated.

IF u need accurate 1 HZ clk then u can find a module inside any battery opearted table clk. U may collect them from junk. I am using it and does not need any calibration....
