AFE7950-TRF1208-EVM Evaluation Module
The evaluation module AFE7950-TRF1208-EVM is used to evaluate the performance of TI's AFE79xx family of
integrated RF sampling transceivers with TI's TRF1208 differential amplifier. The AFE79xx devices support up
to 4 transmit, 4 receive, and 2 feedback channels (4T4R2F) and integrates phase-locked loop (PLL) and voltage-
controlled oscillator (VCO) for generating data-converter clocks. The AFE79xx device integrates 8 JESD204B-
and JESD204C-compatible serializer or deserializer (SerDes) transceivers capable of running up to 29.5 Gbps to
transmit and receive digital data through the onboard FPGA mezzanine card (FMC) connector.
TRF1208 device is a D2D (diff-to-diff) amplifier that either drives the ADC of receive paths (in S2D configuration)
or are driven by the DAC of the transmit path (in D2S configuration). The EVM includes the LMK04828 clock
generator to provide reference clocks and SYSREF to the analog front end (AFE) and capture card (field-
programmable gate array, FPGA). The evaluation module (EVM) works off a single 5.5-V input and includes
complete power management circuitry. External clocking options include support for feeding the reference clock
(for the on-chip PLL). The design interfaces with the TI pattern and capture card solution (TSW14J56 and
TSW14J57), as well as many FPGA development kits.

- Page 1 AFE7950-TRF1208-EVM Evaluation Module ABSTRACT The evaluation module AFE7950-TRF1208-EVM is used to evaluate the performance of TI's AFE79xx family of integrated RF sampling transceivers with TI's TRF1208 differential amplifier. The AFE79xx devices support up to 4 transmit, 4 receive, and 2 feedback channels (4T4R2F) and integrates phase-locked loop (PLL) and voltage- controlled oscillator (VCO) for generating data-converter clocks.
- Page 2 All trademarks are the property of their respective owners. 1 EVM Overview The AFE7950-TRF1208-EVM includes a clocking and power solution, and runs off a single 5.5-V supply. As Figure 1-1 shows, the RF inputs and outputs using SMA connectors are on the top side of the EVM. A reference clock (for example, 10 MHz) to lock the onboard voltage-controlled crystal oscillator (VCXO) with the LMK04828, PLL-1 can be provided to the connector named LMK CLKIN (SMA J15).
- Page 3 (such as signal source, signal analyzer, and so forth) are left to the users' discretion. Note Typically, the bench power supply with a rating of 5.5 V is used to power the AFE7950-TRF1208-EVM. The nominal EVM power supply voltage is 5 V. The additional 0.5-V overhead is added to compensate for the power cable loss as the AFE7950-TRF1208-EVM and TSW14J56/TSW14J57 are configured to full operating mode to accommodate the voltage drop associated with power cable loss.
