Output CML VDDA_HS |
High Speed Transmit Output. HSTXAP and HSTXAN comprise the high speed side transmit direction differential serial output signal. During device reset (RESET_N asserted low) these pins are driven differential zero. These CML outputs must be AC coupled. |

B12 A12 |
Input CML VDDA_HS |
High Speed Receive Input. HSRXAP and HSRXAN comprise the high speed side receive direction differential serial input signal. These CML input signals must be AC coupled. |
INA[3:0]P/N | D1/E1 B2/C2 A1/B1 A4/A3 |
Input CML VDDA_LS |
Low Speed Inputs. INAP and INAN comprise the low speed side transmit direction differential input signals. These signals must be AC coupled. |

LOSA | E9 | Output LVCMOS 1.5V/1.8V VDDO0 40Ω Driver |
Receive Loss Of Signal (LOS) Indicator.
LOS = 0: Signal detected. LOS = 1: Loss of signal. Loss of signal detection is based on the input signal level. When HSRXAP/N has a differential input signal swing of ≤75 mVpp, LOSA is asserted (if enabled). If the input signal is greater than 150 mVpp, LOSA is deasserted. Outside of these ranges, the LOS indication is undefined. |
Other functions can be observed on LOSA real-time, configured via MDIO | |||
During device reset (RESET_N asserted low) this pin is driven low. During pin based power down (PDTRXA_N asserted low), this pin is floating. During register based power down, this pin is floating. | |||
It is highly recommended that LOSA be brought to an easily accessible point on the application board (header) in the event that debug is required. | |||
LS_OK_IN_A | B10 | Input LVCMOS 1.5V/1.8V VDDO0 |
Receive Lane Alignment Status Indicator.
Lane alignment status signal received from a Lane Alignment Slave on the link partner device. Valid in 10G General Purpose Serdes Mode. LS_OK_IN_A = 0: Link partner receive lanes not aligned. LS_OK_IN_A = 1: Link partner receive lanes aligned |
LS_OK_OUT_A | D9 | Output LVCMOS 1.5V/1.8V VDDO 40Ω Driver |
Transmit Lane Alignment Status Indicator.
Lane alignment status signal sent to a Lane Alignment Master on the link partner device. Valid in 10G General Purpose Serdes Mode. LS_OK_OUT_A = 0: Link partner transmit lanes not aligned. LS_OK_OUT_A = 1: Link partner transmit lanes aligned. |
PDTRXA_N | A8 | Input LVCMOS 1.5V/1.8V VDDO0 |

REFCLK0P/N | M10 M11 |
Input LVDS/ LVPECL DVDD |
Reference Clock Input Zero. This differential input is a clock signal used as a reference to channel A. The reference clock selection is done through MDIO. This input signal must be AC coupled. If unused, REFCLK0P/N should be pulled down to GND through a shared 100 Ω resistor. |
REFCLK1P/N | K9 K10 |
Input LVDS/ LVPECL DVDD |
Reference Clock Input One. This differential input is a clock signal used as a reference to channel A. The reference clock selection is done through MDIO. This input signal must be AC coupled. If unused, REFCLK1P/N should be pulled down to GND through a shared 100 Ω resistor. |
CLKOUTAP/N | C9 C10 |
Output CML DVDD |
Channel Output Clock. By default, this outputs is enabled, and outputs the high speed side recovered byte clock (high speed line rate divided by 16 or 20). Optionally, they can be configured to output the VCO clock divided by 2. (Note: for full rates, VCO/2 pre-divided clocks will be equivalent to the line rate divided by 8; for sub-rates, VCO/2 pre-divided clocks will be equivalent to the line rate divided by 4). |
These CML outputs must be AC coupled. | |||
During device reset (RESET_N asserted low), pin-based power down (PDTRXA_N asserted low), or register-based power down, these pins are floating. | |||
PRBSEN | B9 | Input LVCMOS 1.5V/1.8V VDDO0 |
Enable PRBS: When this pin is asserted high, the internal PRBS generator and verifier circuits are enabled on both transmit and receive data paths on high speed and low speed sides. |
The PRBS 27-1 pattern is selected by default, and can be changed through MDIO. | |||
PRBS_PASS | J9 | Output LVCMOS 1.5V/1.8V VDDO1 40Ω Driver |
Receive PRBS Error Free (Pass) Indicator.
When PRBS test is enabled (PRBSEN=1): PRBS_PASS = 1 indicates that PRBS pattern reception is error free. PRBS_PASS = 0 indicates that a PRBS error is detected. The high speed or low speed side, and lane (for low speed side) that this signal refers to is chosen through MDIO. |
During device reset (RESET_N asserted low) this pin is driven high. During pin based power down (PDTRXA_N asserted low), this pin is floating. During register based power down, this pin is floating. |
|||
It is highly recommended that PRBS_PASS be brought to easily accessible point on the application board (header), in the event that debug is required. | |||
ST | M9 | Input LVCMOS 1.5V/1.8V VDDO[1:0] |
MDIO Select. Used to select Clause 22 (=1) or Clause 45 (=0) operation. Note that selecting clause 22 will impact mode availability. See MODE_SEL. |

PRTAD[4:0] | M8 J6 L9 G9 E10 |
Input LVCMOS 1.5V/1.8V VDDO[1:0] |
MDIO Port Address. Used to select the MDIO port address. |
PRTAD[4:1] selects the MDIO port address. The TLK10031 has one MDIO port addresses. Selecting a unique PRTAD[4:1] per TLK10031 device allows 16 TLK10031 devices per MDIO bus. | |||
The TLK10031 responds if the 4 MSB’s of the port address field on MDIO protocol (PA[4:1]) matches PRTAD[4:1], and PA[0] = 0. | |||
PRTAD0 is not needed for port addressing, but can be used as a general purpose input pin to control the switching function or the stopwatch latency measurement. If these functions are not needed, PRTAD0 should be grounded on the application board. | |||
RESET_N | H5 | Input LVCMOS 1.5V/1.8V VDDO01 |

MDIO | J7 | Input/ Output LVCMOS 1.5V/1.8V VDDO1 25Ω Driver |
MDIO Data I/O. MDIO interface data input/output signal for the MDIO interface. This signal must be externally pulled up to VDDO using a 2-kΩ resistor. |
During device reset (RESET_N asserted low) this pin is floating. During software initiated power down the management interface remains active for control register writes and reads. Certain status bits will not be deterministic as their generating clock source may be disabled as a result of asserting either power down input signal. During pin based power down (PDTRXA_N asserted low), this pin is floating. During register based power down, this pin is driven normally. | |||
TDI | C8 | Input LVCMOS 1.5V/1.8V VDDO0 (Internal Pullup) |
JTAG Input Data. TDI is used to serially shift test data and test instructions into the device during the operation of the test port. In system applications where JTAG is not implemented, this input signal may be left floating. During pin based power down (PDTRXA_N asserted low), this pin is not pulled up. During register based power down, this pin is pulled up normally. |
TDO | D6 | Output LVCMOS 1.5V/1.8V VDDO0 50Ω Driver |
JTAG Output Data. TDO is used to serially shift test data and test instructions out of the device during operation of the test port. When the JTAG port is not in use, TDO is in a high impedance state. During device reset (RESET_N asserted low) this pin is floating. During pin based power down (PDTRXA_N asserted low), this pin is not pulled up. During register based power down, this pin is pulled up normally. |
TMS | B8 | Input LVCMOS 1.5V/1.8V VDDO0 (Internal Pullup) |

JTAG Test Reset. TRST_N is used to reset the JTAG logic into system operational mode. This input can be left unconnected in the application and is pulled down internally, disabling the JTAG circuitry. If JTAG is implemented on the application board, this signal should be deasserted (high) during JTAG system testing, and otherwise asserted (low) during normal operation mode. During pin based power down (PDTRXA_N asserted low), this pin is not pulled up. During register based power down, this pin is pulled up normally. |
TESTEN | L10 | Input LVCMOS 1.5V/1.8V VDDO1 |
