TLK110 SLLS901C – DECEMBER 2011 – REVISED JUNE 2013 5.1.5 www.ti.com Digital to Analog Converter The multipurpose programmable transmit Digital to Analog Converter (DAC) receives digital coded symbols and generates filtered analog symbols to be transmitted on the line. In 100B-TX the DAC applies a low-pass shaping filter to minimize EMI. The DAC is designed to improve the return loss requirements and enable the use of low-cost transformers.
TLK110 www.ti.com 5.2.5 SLLS901C – DECEMBER 2011 – REVISED JUNE 2013 Descrambler The descrambler is used to descramble the received NRZ data. The data is further deserialized and the parallelized data is aligned to 5-bit code-groups and mapped into 4-bit nibbles. At initialization, the 100BTX descrambler uses the IDLE-symbols sequence to lock on the far-end scrambler state. During that time, neither data transmission nor reception is enabled.
TLK110 SLLS901C – DECEMBER 2011 – REVISED JUNE 2013 www.ti.com 5.2.10 Signal Detect The signal detect function of the TLK110 is incorporated to meet the specifications mandated by the ANSIFDDI TP-PMD Standard as well as the IEEE 802.3 100Base-TX Standard for both voltage thresholds and timing parameters. The energy-detector module provides signal-strength indication in various scenarios. Because it is based on an IIR filter, this robust energy detector has excellent reaction time and reliability.
TLK110 www.ti.com 5.3.4 SLLS901C – DECEMBER 2011 – REVISED JUNE 2013 Jabber Function Jabber is a condition in which a station transmits for a period of time longer than the maximum permissible packet length, usually due to a fault condition. The jabber function monitors the TLK110 output and disables the transmitter if it attempts to transmit a packet of longer than legal size. A jabber timer monitors the transmitter and disables the transmission if the transmitter is active for approximately 100ms.
TLK110 SLLS901C – DECEMBER 2011 – REVISED JUNE 2013 www.ti.com When auto negotiation has started, the TLK110 transmits FLP on one twisted pair and listens on the other, thus trying to find out whether the other link partner supports the auto negotiation function as well. The decision on what pair to transmit/listen depends on the MDI/MDI-X state. If the other link partner activates auto negotiation, then the two parties begin to exchange their information.
TLK110 www.ti.com 5.4.4 SLLS901C – DECEMBER 2011 – REVISED JUNE 2013 Next Page Support The TLK110 supports the optional feature of the transmission and reception of auto-negotiation additional (vendor specific) next pages. If next pages are needed, the user must set register ANAR(0x0004h) bit 15 to '1'. The next pages are then sent and received through registers ANNPTR(0x0007h) and ANLNPTR(0x0008h), respectively.
TLK110 SLLS901C – DECEMBER 2011 – REVISED JUNE 2013 www.ti.com The Fast Link Down functionality allows the use of each of these options separately or in any combination. Note that since this mode enables extremely quick reaction time, it is more exposed to temporary bad linkquality scenarios.
TLK110 www.ti.com SLLS901C – DECEMBER 2011 – REVISED JUNE 2013 6 Reset and Power Down Operation The TLK110 includes an internal power-on-reset (POR) function, and therefore does not need an explicit reset for normal operation after power up. At power-up, if required by the system, the RESET pin (active low) should be de-asserted 200µs after the power is ramped up to allow the internal circuits to settle and for the internal regulators to stabilize.
TLK110 SLLS901C – DECEMBER 2011 – REVISED JUNE 2013 6.4 www.ti.com Power Save Modes The TLK110 supports three types of power-save modes. The lowest power consumption is achieved in IEEE power down mode. To enter IEEE power down mode, pull the INT/PWDN pin to LOW or program bit 11 in the Basic Mode Control Register (BMCR), address 0x0000. In this mode all internal circuitry except SMI functionality is shut down (Register access is still available).
