detailed description
data transmission
These devices support both the defined 10-bit interface (TBI) and a reduced 5-bit interface utilizing DDR
clocking. When MODESEL is low, the TBI mode is selected. When MODESEL is high, the DDR mode is
selected.
In the TBI mode, the transmitter portion registers incoming 10-bit wide data words (8b/10b encoded data,
TD0
–
TD9) on the rising edge of REFCLK. The REFCLK is also used by the serializer, which multiplies the clock
by a factor of 10, providing a signal that is fed to the shift register. The 8b/10b encoded data is transmitted
sequentially bit 0 through 9 over the differential high-speed I/O channel.
In the DDR mode, the transmitter accepts 5-bit wide 8b/10b encoded data on pins TD0
–
TD4. In this mode data
is aligned to both the rising and falling edges of REFCLK. The data is then formed into a 10-bit wide word and
sent to the serializer. The rising edge REFCLK clocks in bit 0
–
4, and the falling edge of REFCLK clocks in bits
5
–
9. ( Bit 0 is the first bit transmitted).
