[time-nuts] 1PPS to 32.768 khz

Welcome to the list! I happen to have just installed a Leo Bodnar GPSDO and it is running currently here. It is a *very* nice unit, well thought out, and nicely put together. The price is a bit steep for an entry level device, however I feel it is work it.
Another wonderful unit can be found here: https://www.tindie.com/products/nsayer/gps-disciplined-xcxo/
I also have this unit and it is the 10MHz standard on my workbench. Another quality product, it is well designed and put together.
You can't go wrong with either of these units. The LeoNTP is more for serving ntp to clients, the Nick Sayer one more for a frequency standard.

First let me say this is first time I have posted to the group so go easy on me. :) Secondly I want everyone to know that you guys make me feel so NORMAL for wanting to use and understand accurate timing devices.
I thought there was something seriously wrong with me now I know there are others affected with the same disease. hehe
Now my questions.
1. Does anyone know of a device that will take a 1PPS GPS timing signal and generate a 32.768 kHz sine wave output ?
I have big digital clock that uses an 8 bit micro processor and an external 32.768 crystal. Obviously the external crystal is awful for accuracy.
I have searched every where using as many search terms as I can think of and can’t believe there is not a device that performs this function.
I have found a couple of Epson RTC chips that might come close that 1pps but I don’t think that corrects the 32khz just the clock time.
2. 10 Mhz Freq Standard
I am not in the same league as the majority of the list members and just starting to dabble in GPSDO stuff.
I have tried to find a thunderbolt as a starting device but it appears those are either dried up or people want too much money.
I wanted to get the opinion of anyone who has tried the Leo Bodnar GPSDO ?
For the money it appears to offer a beginner a lot of features.
Thanks and reading the daily digest of what you guys are working on.
I have a feeling if I am not careful you guys could cost me a lot of money. hehe
