Clock Requirement of the board is as mentioned below.
I would like to know whether the clock source which I want to use it for SYSLK ,is it possible to use for SERDES clock(SRIO) by using a synthesizer and jitter cleaner.( for eg:CDCE 706 is having 6 programmmable port.ONE port we can use it for SYSCLK , 61.42MHz and One port for SERDES Clock, 125Mhz controlled by using I2C).In EVM module, it is using seperate 125MHz crystal for doing the same.
Please kindly suggest.
Thanks and regards,
TMS 320C6474(Requirement is for 8 DSP Processors)
SYSCLK - 61.44 MHz - 2 PS RMS
DDRCLK - 66.0MHz - 30 PS RMS
SRIO/EMAC - 125 MHz - 4 PS RMS
FRAMESYNC - 30.72 MHz - 800PS RMS (SHOULD BE DERIVED FROM BUFFER WHICH GIVES SYSCLK)
S_CLK - 156.25 MHz - 3PS RMS
P_CLK - 100MHz - 300PS PP
XIN - 12MHz - NO JITTER SPEC
XIN32 - 32.684KHz - NO JITTER SPEC
XCLK ( FRAMESYNC) - 30.72 MHz - 800PS RMS (SHOULD BE DERIVED FROM BUFFER WHICH GIVES SYSCLK)
XCLK1 - 25MHz(FROM BACKPLANE REFERANCE CLK)
XIN - 25MHz
