ORCA ORT42G5 and ORT82G5 Data Sheet
16
Transmit Path (FPGA to Backplane) Logic
The transmitter section accepts four groups of either 8-bit unencoded data or 10-bit encoded data at the parallel
interface to the FPGA logic. It also uses the reference clock, REFCLK[P:N]_[A:B] to synthesize an internal high-
speed serial bit clock. The serialized transmitted data are available at the differential CML output pins to drive either
an optical transmitters, coaxial media or a circuit board backplane.
As shown in Figure 3, the basic blocks in the transmit path include:
Embedded Core/FPGA interface and 4:1 multiplexer
Low speed parallel core/FPGA interface
4:1 multiplexer
Transmit SERDES
8b/10b Encoder
10:1 Multiplexer
CML Output Buffer
Detailed descriptions of the logic blocks are given in following sections. Detailed descriptions of transmit clock dis-
tribution, including the transmit PLL are given in later sections of this data sheet.
