do u need sharp exectly this same frequency,why not u try crystal oscillator,it is nearly 11.059 MHz,check out any oscillaotr like colpit or hartly,or any which u can make easily
If you mean exactly 11.0592Mhz, a programmable crystal oscillator would be an economic and easy solution. E.g.:www.cardinalxtal.com. You need a programmer device, but distributors are ususally willing to program the parts to your required frequency.
You'll notice, that I generally try to help. I also made a very specific suggestion on your question (in another thread), although I was guessing to some extend. But as you started to complain about other contributions, I must confess, that I sometimes get upset about unclear questions.
11.0592MHz is usualy used in microcontroller systems or other systems that have UART communication. This frequency feeding the baud rate generator, permits baud generation with 0% error.
On the market there are plenty 11.0592MHz quartz crystals - this is a "standard" frequency. Just design a quartz oscillator followed by a buffer gate with HCMOS/TTL chip and you will get a square signal. If you do IC design use a simple CMOS inverter biased in the linear region resistor paralleled with crystal.
You need to have at least a decent attitude when replying to experienced and helpful users on the forum!
If you need very pure 11.5Mhz square pulse then the one of the way to use Direct Digital Frequency Synthesizer...a digital version of VCO...
for normal applications with not much precicion...you can use a crystal oscillator together with some oscillator circuit...or any high slew rate apamp in astable multivibrator configuration.
