How does the Flexible-LVDS feature in Mercury devices work?
The EP1M350 devices will offer over 100 channels of Flexible-LVDS capability with support at up to 624 Mbps via internal dedicated buffers. Q: How is the Mercury True-LVDS feature different from the APEX 20KE/C True-LVDS feature? A: In Mercury devices, the multiplication factor, W, and the serialization/deserialization factor, J, can differ from each other, whereas in APEX 20KE and APEX 20KC devices, these two factors must be the same. This allows Mercury devices to support standards, such as RapidIO, that require the clock to be half of the data rate. Additionally, the Mercury True-LVDS feature supports a wider range for both the W and J factors. Q: What are the W and J factors for the Mercury True-LVDS feature? A: In source-synchronous mode, W can be 1 to 12, 14, 16, 18, or 20, and J can be 4, 7 to 12, 14, 16, 18, or 20. Q: How many different frequencies will be supported simultaneously in the Mercury True-LVDS feature? A: Mercury source-synchronous mode can support two separate freq
