SLOSE75B February 2022 – March 2023 TAS2780
PRODUCTION DATA
The TAS2780 has a dedicated ICC bus pin that enables gain alignment (ICGA) without consuming slots on the TDM bus. The ICC pin is connected to all TAS2780 devices in the system and slots are configured using register bits GAIN_SLOT[5:0]. This bus uses the TDM (Section 8.4.1) BCLK and FSYNC inputs and requires all devices to be configured using the same sampling clock. The ICC pin supports separate bus keeper configuration from the SDOUT pin (TDM bus). If the ICC pin is disabled or used for GPIO functionality, the ICGA (Section 8.4.2.10) will occur on the TDM bus instead of the ICC pin. Register bits ICC_MODE[2:0] are used to set the ICC pin functionality.
