Figure 3. Transmission Latency
8-Bit/10-Bit Encoder
All true serial interfaces require a method of encoding to insure minimum transition density so that the receiving
PLL has a minimal number of transitions to stay locked on. The encoding scheme maintains the signal dc
balance by keeping the number of ones and zeros the same. This provides good transition density for clock
recovery and improves error checking. The TLK2711A uses the 8-bit/10-bit encoding algorithm that is used by
fibre channel and gigabit ethernet. This is transparent to the user, as the TLK2711A internally encodes and
decodes the data such that the user reads and writes actual 16-bit data.
The 8-bit/10-bit encoder converts 8-bit wide data to a 10-bit wide encoded data character to improve its
transmission characteristics. Since the TLK2711A is a 16-bit wide interface, the data is split into two 8-bit wide
bytes for encoding. Each byte is fed into a separate encoder. The encoding is dependent upon two additional
input signals, the TKMSB and TKLSB.

PRBS Generator
The TLK2711A has a built-in 27-1 PRBS (pseudorandom bit stream) function. When the PRBSEN terminal is
forced high, the PRBS test is enabled. A PRBS is generated and fed into the 10-bit parallel-to-serial converter
input register. Data from the normal input source is ignored during the PRBS mode. The PRBS pattern is then
fed through the transmit circuitry as if it were normal data and sent out to the transmitter. The output can be sent
to a BERT (bit error rate tester), the receiver of another TLK2711A, or looped back to the receive input. Since the
PRBS is not really random but a predetermined sequence of ones and zeroes, the data can be captured and
checked for errors by a BERT.
Parallel-to-Serial
The parallel-to-serial shift register takes in the 20-bit wide data word multiplexed from the two parallel 8-bit/10-bit
encoders and converts it to a serial stream. The shift register is clocked on both the rising and falling edge of the
internally generated bit clock, which is 10 times the TXCLK input frequency. The LSB (TXD0) is transmitted first.
