TDA2SX: VOUT spread spectrum feature

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?
