This post is going to be about Repair of old HP Infiniium 5815A 500Mhz oscilloscope. Scope has normal PC motherboard with Windows 98. Scope has issue booting into windows because DS12887A RTC which scope's motherboard uses has internal battery. And because of RTC battery being empty scope has CMOS checksum bad and can not boot as it has forgotten all boot settings. I will try to fix DS12887A and restore setting to CMOS memory.

Making Opensource USB C industrial camera with Interchangeable C mount lens, Interchangeable MIPI Sensor with Lattice Crosslink NX FPGA and Cypress FX3 USB 3.0 controller
Thursday, May 19, 2022
From quite some time i have been working with different MIPI CSI Camera Solutions , Interfacing Camera with FPGA and Connecting to USB 3.0 Connection.
Board will be having USB C connector for USB 3.0 5Gbps Connection with Cypress FX3 CYUSB3014 and Lattice Crosslink FPGA
|Board With Direct Raspberry PI IMX219|
|Board with FCP Connector for Any MIPI Camera With 1mm Flex cable|

Agilent Keysight 53220A Universal Frequency Counter Option 010 Ultra High Stability OCXO Timebase Upgrade
I have previously upgraded Timebase for Agilent/HP 53132A Universal frequency counter and also PM66xx Counter. This time i will be upgrading Keysight 53220A.
This upgrade is going to be little different as keysight 53220A does not have a oscillator module. OCXO is directly soldered to the main board. So this upgrade is just going to be desoldring existing TCXO and mounting correct OCXO to have Option 010 Ultra High Stability OCXO Timebase activated.
Quite a while ago I had written about how I upgraded oscillator of my Agilent/HP 53132A. I have recently bought a broken Fluke/Philips PM6680B Frequency counter. Though i was able to quickly fixed issues with the unit by replacing power supply capacitors, the unit still has really crappy original reference oscillator. So I decided to make my own PM9692 Ultra High Stability Oven Time Base with CTS 196 OCXO.

So i made this Open source Board, With three separate switching regulator for each bank VCCIO on 4 Layer Gold finish board with most of microZed pins broken out in LVDS pair. PCB is 4 Layer impedance control for 100R LVDS pair. Board has 3 solder jumpers per regulator to change bank voltage of each bank separately.

Currently i am trying to interface Raspberry pi camera V2.1 sony IMX219 Camera to Lattice FPGA then ultimately to USB 3.0 with Cypress FX3 USB 3.0 controller.
As per schematic of Raspberry pi and Raspberry PI Camera module. It is two lane MIPI CSI Camera Board with 1 Clock and 2 MIPI CSI data lane.

DIY USB 3.0 1080p Full HD Camera with Auto Focus and 10x Optical zoom, 1Gbps Streaming Over Cypress FX3 USB3.0
In this post i will be using powerful cypress FX3 CYUSB3014 USB controller board to interface PE1005 Camera module to USB 3.0. This post will overcome the limits imposed by OV7670 in the last post. OV7670 was just a VGA camera. but PE1005 is full HD 1080p 30PFS camera module with really nice features like Auto focus, 10x optical Zoom, F1.8-2.2 Mechanical Shutter. Electronic image stabilizer.
This camera module is from company called Acutelogic HK limited i received this camera from a eevblog forum member a while back.
