TMS320F280049: One SD clock for all four channels?

Part Number: TMS320F280049

Dear Champs,

I am asking this for our customer.

In this post, 

TMS320F28388D: Sigma Delta Filter Module(SDMF) Different Clock Modes? - C2000 microcontrollers forum - C2000Tm︎ microcontrollers - TI E2E support forums

"You don't need to be a clock master to use clock control feature. From a hardware perspective, you need to route AMC1303M Clock signal to SD-C1 (Filter channel 1 clock). This clock can then be used internally to all the other 3 filter channels (2 / 3 / 4)."

Because the user has limited usable pins, they want to use as few clock pin as possible for SDFM.

Would you please confirm?

On 100-pin F280049, is the internal clock sharing also valid? That is, the user can use single pin for clocking SD1-CK1 and all other SD1-CK2/3/4 share the same clocking SD1-CK1?

Is our understanding correct?
