Quartz crystal for TRS-80

------Question for 830003051B Please Put your question below------

Hello kramer_ae,

Welcome to the DigiKey TechForum.

We do have the 830003051B quartz crystal in stock. Here is the data sheet for more info on it: WE Part Data Sheet V1.0025

Regards,

Thank you for your quick reply.

I just gave you the existing part no as a starting point.

In the details of the request I said that the actual component needs to be 10.6445 Mhz like the one pictured here:

If you need a crystal at frequency 10.6445Mhz unfortunately we do not have anything to offer.

Your E-bay example they indicate they had to get that frequency custom manufactured for them.

About the only thing we could offer you which might possibly work would be to use a programmable oscillator, such as this:

ECS-P85-B Frequency-programmable 5V oscillator

At the time one places an order for this part, you specify the desired frequency in the order notes and we’ll program it to that frequency before shipping.

To make this work, you would need to make a separate circuit near the TRS-80 oscillator circuit. Assuming the TRS-80 oscillator circuit uses a 5V rail, you would provide this device with a 5V supply along with a ground connection, and then feed the output of this oscillator into the correct input pin of the TRS-80 oscillator circuit (there would likely be an input and output on the TRS-80 oscillator circuit that you would have to figure out).

Thank you for the alternative, David! I’ll keep that in mind if I decide not to spend the extra money from a supplier in the UK!
