CDCM6208: use CDCM6208 to generate 15 clocks

Part Number: CDCM6208

Hi team,

Can I generate 15 clocks below using 2 CDCM6208?

103.125M, 125M*5, 135M*2 148.5/1.001M, 148.5M, 156.25M*4, 200M

Regards,

Yangbo

  • 148.5/1.001M means the clock is 148.5 divide by 1.001

    Hi Yangbo,
    Sorry for the delay in response here. You best option would be to use 2, LMK03328's for meeting this requirement (could fall a little short on the total number of clocks required). The first LMK03328 could be used to generate 148. 5MHz, 148.5/1.001 MHz and 135 MHz (x2) using an off the shelf crystal/XO. The second LMK03328 can generate the 4 copies of 156 MHz, 2 copies of 125 MHz, 200 MHz and 103.125 MHz. So you may fall short of 3, 125 MHz clocks that could potentially be addressed via a simple 1: 4 buffer (LMK00304). LMK03328 has superior performance compared to CDCM6208 and has an integrated EEPROM.
