Frequency Range On LVPECL Output of CY22394.
Does the CY22394 support frequencies less than 100 MHz on the LVPECL output? Both the PLL selection window and the divider window are grayed out for a default of PLL1 and divide by '1'. Also Cyclock RT does not allow a selection of low frequency in the 25 MHz range.
The CY22394 PECL output frequency range is from 100-400MHz, and the divider value is fixed to 1. Other Cypress devices (such as the
CY2DP814, which works from DC to 400MHz) can take in a single-ended input and output a differential pair. Also, look at High Performance Buffers with LVPECL outputs.
