Converter Device | ADC or DAC converter |
Logic Device | FPGA or ASIC |
Octet | A group of 8 bits, serving as input to 8B/10B encoder and output from the decoder |
Data Rate | Effective data rate per lane for serial link Data Rate = Sampling rate per converter x M x N' x (10/8)/L
Note: Sampling rate in Msps (Mega samples per second); Data rate in Mbps (Megabits per second)
|
Link Clock | The associated parallel data bus is 40 bits wide. Link Clock = Data Rate/40. |
Frame | A set of consecutive octets in which the position of each octet can be identified by reference to a frame alignment signal. |
Frame Clock | A system clock which runs at the frame's rate. |
Samples per frame clock | Samples per clock, the total samples in frame clock for the converter device. |
LMFC | Local multiframe clock is counter generated from the link clock and depends on the F and K parameters. LMFC Period = (FxK/4) x Link Clock Period; the value of FxK must be divisible by 4. |
Subclass 0 | No support for deterministic latency. Data should be immediately released upon lane to lane deskew on receiver. |
Subclass 1 | Deterministic latency using SYSREF. |
Multipoint Link | Inter-device links with 2 or more converter devices. |
