abstract = {We will start a full energy injection from the SACLA to the SPring-8 from next year as a part of the SPring-8 upgrade. For this, we developed several I/O cards with the MTCA.4 form factor. One of the key issues is a timing synchronization between SACLA and SPring-8. We implemented required functions on the FPGA logic of a commercially available I/O card. We develop a module to distribute a trigger and clocks. We also developed cards used for the beam position monitor (BPM) and low-level RF system (LLRF). Those are included two types of cards. One is a 16-bit digitizer used for LLRF for the SPring-8 since 2018 march. We will use the card for the BPM with modified FPGA logic. Second is an implementation of functions with the pulsed RF signals processed on the FPGA logic of a commercially available card. These functions are used for the BPM of the beam transport line from the SACLA to SPring-8. The existing system is used 1 Hz beam repetition but we need more than 10 Hz to achieve an injection time less than 20 minutes to maximize user time. We will report the performance of the MTCA.4 cards, the upgrade plan of the SPring-8, and the construction of the 3 GeV Light Source.},
