11 / 58 page DocID028727 Rev 1 11/58 ST-PLC-AFE General description 58 2.2 Tx block The Tx block is divided into an internal DAC, an internal fourth-order filter, a programmable amplifier, and a power liner driver. There are two ways to drive this transmission line: 1. The internal DAC driving mode, achieved through the SPI interface and the internal 10-bit DAC. 2. Using an external driving mode where the signal received by the ST-PLC-AFE is purely analog, coming from an external MCU DAC. This signal is applied on the TX_INP input pin. Tx PGA can be configured through the SPI to operate as an attenuator or to work in follower. The gain steps of the Tx PGA are 6 dB, 0 dB, -18 dB, and -36 dB. The gain can be programmed through the TX_PGA1<1:0> bits in the Gain register. The Tx_filter is a unity-gain, fourth-order, low-pass filter. Its cutoff frequency is selectable between CENELEC A or CENELEC B, C, or D modes. The selection of the band is achieved through the BAND_SEL bit in the Enable register. 2.2.1 Internal DAC driving mode The ST-PLC-AFE accepts serial data from the microprocessor and writes the data to the internal DAC registers. Operating in DAC mode results in the lowest distortion signal injected onto the AC mains. DAC mode is selected by setting the DAC_EN bit in the Enable register to 1. Figure 5 and Figure 6 show the connection to the power line while using the internal DAC in differential mode and in single-ended mode respectively. Figure 5.
