SLAU957 June 2025 TRF1108 , TRF1208
The TRF-LSC-AFE7950EVM includes a clocking and power solution, and runs on a single 5.5V supply. TRF-LSC-AFE7950EVM Board shows that the RF inputs and outputs using SMA connectors are on the top side of the EVM. Use a 10MHz reference clock through the SMA J15 (LMK_CLKIN) connector to lock the onboard voltage-controlled crystal oscillator (VCXO) with the LMK04828. Typically, lab equipment has a 10MHz oscillator output to synchronize multiple lab systems. The onboard LMK04828 accepts the 10MHz clock from the external lab equipment to maintain synchronization and coherency of the data capture and generation to the TRF-LSC-AFE7950EVM.
Figure 1-1 TRF-LSC-AFE7950EVM Top ViewTo feed an external reference clock to lock the PLLs in the AFE79xx, use SMA J13 (REF_CLK_HIGH) or SMA J14 (REF_CLK_LOW). The USB connector and the 5.5V connector are on the right side of the board.
Figure 1-2 shows the bottom view of the TRF-LSC-AFE7950EVM.
Figure 1-2 TRF-LSC-AFE7950EVM Bottom ViewThe capture card used with the TRF-LSC-AFE7950EVM is typically the TSW14J56EVM or TSW14J57EVM. The TSW14J56EVM supports a SerDes speed up to 12.5Gbps and the TSW14J57EVM supports up to 15Gbps. The choice between the TSW14J56EVM or TSW14J57EVM depends on the AFE79xx JESD204 configuration and the associated SerDes rate.
