7.4.2.5.1 Test Pattern Generator
In 1G-KX mode, this block can be used to generate test patterns allowing the 1G-KX channel to be tested
for compliance while in a system environment or for diagnostic purposes. Test patterns generated are
high/low/mixed frequency and CRPAT long or short.
7.4.2.5.2 Test Pattern Verifier
The 1G-KX test pattern verifier performs the verification and error reporting for the CRPAT Long and Short
test patterns specified in Annex 36A of the IEEE 802.3-2008 standard. Errors are reported to MDIO
registers.
7.4.3 General Purpose (10G) Serdes Mode Functional Description

7.4.3.1 General Purpose SERDES Transmit Data Path
The TLK10031 General Purpose SERDES low speed to high speed (transmit) data path with the device
configured to operate in the normal transceiver (mission) mode is shown in the upper half of Figure 7-10.
In this mode, 8B/10B encoded serial data (INA*P/N) in 2 or 4 lanes is received by the low speed side
SERDES and deserialized into 10-bit parallel data for each lane. The data in each individual lane is then
byte aligned (channel synchronized) and then 8B/10B decoded into 8-bit parallel data for each lane. The
lane data is then lane aligned by the Lane Alignment Slave. 32 bits of lane aligned parallel data is input to
a transmit FIFO which delivers it to an 8B/10B encoder, 16 data bits at a time. The resulting 20-bit 8B/10B
encoded parallel data is sent to the high speed side SERDES for serialization and output through the
HSTXAP*P/N pins.
