The specific part is obsolete and no longer available. The fact also worth mentioning is that clock levels logic 0 and logic 1 for are simple TTL ones, unlike, for example, i and Z The wave output from the CLK pin looks like this: However, it looks like the capacitors are discharging too soon.

This is the acceptable operating range of datashwet device. The datasheet link says “Your require pages is cannot open by blow”: Also, please note the warehouse location for the product ordered.

As an aside, I’d really like to hear comments from anyone who’s done this, as I have plans at some point in my future for a custom build, and this calculation should apply there, also All old XT computers will have it. We have started to cover the Intel chip in my microprocessor class but unfortunately the class only covers textbook and Assembly stuff, not the actual hands on hardware.

First let see what tasks does, according to its datasheet http: It makes clock for of special shape like Please Select a Language.

Because the just has a single clock input pin, would I be able to hook up a different method of clock generation? Please Select a Region. The model has not been released to general production, but samples may be available. For 5MHz usage, you’d use it with an external 30MHz crystal, and set up two of its PWM outputs to produce a 2-cycle high, 4-cycle low output for the CPU clock and a 3-cycle high, 3-cycle low output for the peripheral clock.

BTW, your reset wiring is incorrect. Due to environmental concerns, ADI offers many of our products in lead-free versions. Email Required, but never shown. Email Required, but never shown. I thought the systems clock would be a good place to start. I did an exhaustive search and could not find a new parts supplier, or even an international supplier like AliExpress or Futurlec that carries it.

We do take orders for items that are not in stock, so delivery may be scheduled at a future date. As pointed out by ChrisStratton in comments to lvd’s answer, you can easily use a modern microcontroller to produce the required signals.

The model is currently being produced, and generally available for purchase and sampling. You’d also have plenty of spare PWMs this chip has 10 of them which could be used for other useful clocks: I’ve still got to build my ultimate Z80 machine, which I haven’t even finished doing the research for yet.

The package for this IC i. The long answer is the functions could be duplicated by extensive external circuitry, but why would you want to?

Just that you have to run it slower in order to do so. If you really want maximum performance, getting one would probably be the easiest way of achieving that. There are 3 more available; you can use 2 of them for a reset switch input and RESET signal output and have then entirely duplicated the functionality of the These days you can probably with cleverness accomplish that with an MCU’s hardware timers, or a tiny CPLD, or assorted selections from several decades worth of clock and timing chips.

Status Status indicates the current lifecycle of the product.

The key things are that the edges are monotonic no glitches or “hooks” near the logic thresholds and that the spacing of the crossings about halfway between the peaks, third line down on the ‘scope graticule has the right timing frequency and duty cyclewhich it does.

None of the vendors I use regularly stock them, so you’re dtasheet at the very least a long wait while they order them in, and you may be looking at a fairly large minimum order. The output is extremely close to 5Mhz. Comparable Parts Click to see all in Parametric Search.
