Ticket Name: TDA2SX: VOUT spread spectrum feature Query Text: Part Number: TDA2SX Other Parts Discussed in Thread: TDA2 Hello Team, My customer asked that Spread spectrum feature is supported on VOUT1 port due to EMI issue at VOUT1 PCLK frequency. In TDA2 TRM (TDA2x_SR2.0_SR1.x_NDA_TRM_vAD.pdf), there is a register (PLL_SSC_CONFIGURATION1) which can enable SSC feature on DPLL_VIDEO1 as below. On the other hand, it is noted that "SSC feature is not supported." Customer would like to know that they can use SSC feature on DPLL_VIDEO1 by enabling "PLL_SSC_CONFIGURATION1[EN_SSC]" register. How it would work when EN_SSC is enabled? Responses: Hi Lloyd, SSC was not tested for one reason or another. Your customer may try it and use it if everything is fine, but TI will not be able to support them. Regards, Stan |
