Application Note 1513 Operation of Evaluation Board After a brief description of the board design and layout, the different features and options to operate the board are highlighted. • Providing power to the board through an external supply • The eight high speed differential I/O PROVIDING POWER FROM EXTERNAL 5V POWER SUPPLY The evaluation board can also be powered by an independent external 5.0V power supply via header P1 as highlighted on Figure 4. The maximum current consumption for the board including the voltage regulators, microcontroller circuits and the IC together is approximately 245mA with all channels active. • The impedance select function • The variable detection threshold • Controlling the equalizer boost via control pins QLx4600-S30 Evaluation Board The QLx4600-S30 evaluation board is a 4-layer, 4”(w)x5.6”(h)x0.059”(t) in dimension, and fabricated with (Allied-Signal) FR-408 dielectric material. 100Ω differential signal traces are laid out with 0.0062” width and 0.0058” spacing. 50Ω single-ended traces are 0.009” wide. Figure 3 shows the top view of the board. FIGURE 4. QLX4600-S30 EVALUATION BOARD EXTERNAL POWER SUPPLY POWER CONNECTOR Table 1 provides description of the connector P1. A power cable is provided with the evaluation board. TABLE 1. P1 CONNECTOR DESCRIPTION 8 – NC 7 – NC 6 – 5.0V 5 – 5.0V 4 – NC 3 – NC 2 – GND 1 – GND High Speed Data_I/O Interface Connectors There are sixteen SMA connectors on the board, eight for the CML differential inputs and eight for the CML differential outputs. All the connections from the SMA connectors to the QLx4600-S30 series chip are AC-coupled with a 220nF broadband capacitor. Figure 5 on page 3 shows each channel by their name, direction and their polarities. Detection Threshold (DT) The DT is another very important feature of the QLx4600-S30 series IC. On the evaluation board, the DT can be changed by adjusting the potentiometer VR1 (Figure 6 on page 3). In normal operation, the potentiometer should be set so that the voltage across the adjacent 10k resistor is 0V. For applications that need to adjust this level, it can be simply done by changing the potentiometer and reading the voltage across the 10k resistor in order to infer the current coming from the DT pin. FIGURE 3. QLX4600-S30 EVALUATION BOARD PCB OUTLINE Power Supply For example, measuring a voltage of -200mV across the 10k resistor indicates a 20µA current from the DT pin. Power can be supplied to the board by using an external power supply. On-board voltage regulators supply the appropriate 1.2V to the QLx4600-S30 IC.

QLX4600-S30 EVALUATION BOARD IMPEDANCE SELECT Impedance Select Two 3x2 headers, JP4 and JP5, provide interfaces to the “impedance select” pins of the QLx4600-S30 series ICs. With this function, the user can put any equalizer channel into a standby or reset state by placing a jumper across the header for the selected channel. When in the reset state, the single-ended input impedance of the equalizer channel goes in excess of 200kΩ (from its nominal value of 50Ω) to indicate to a transmitter that the receiver channel is down and not passing data. Additionally, power consumption for a channel is reduced when in the standby state. TABLE 2. DESCRIBES JP4 AND JP5 CONNECTIVITY JP4 JP5 2 - IS1 4 - IS2 6 - GND 2 - Mode 4 - IS4 6 - IS3 1 - GND 3 - GND 5 - GND 1 - GND 3 - GND 5 - GND Boost Setting Control Pins In order to enable boost setting control via the control pins, JP5-Pin 2 must be jumpered to ground. The boost setting configuration (compensation setting) for each individual equalizer channel is done through a 3x3 header. There are four sets of headers, one for each equalizer channel. Figure 8 illustrates the location of the headers. FIGURE 8. EQUALIZER BOOST CONTROL HEADERS Submit Document Feedback 4 AN1513.1 June 24, 2016 Application Note 1513 The notation CP[1-4]_[A – C] refers to the QLx4600-S30 quad equalizer CPs. They are associated with the 4 channels 3-digit number where ‘A’ is the MSB and ‘C’ is the LSB. Table 3 describes the relationship between the CPs and the equalizer boost setting. Bit A can only take one of two values, either Low (L) or High (H), while bit B and C can take one of three values, Low (L), Middle (M) and High (H). Hence, eighteen of the thirty-two different boost levels are accessible through the CPs for each equalizer channel. For Channels 3 and 4, we use headers JP1-3 in a similar fashion except High is achieved using the bottom two pins and middle is achieved by using the top two pins. Figure 10 illustrates how one could set the CPs for a boost value of 18 (H, L, M) on Channel 3 and a value of 14 (L, H, M) on Channel 4. On Figure 10 please also note how pin 2 on JP5 is jumpered to ground in order to enable the CP control feature. TABLE 3.

ILLUSTRATION OF SETTINGS FOR CP3 = (H, L, M) AND CP4 = (L, H, M) For Channels 1 and 2, the headers JP6-8 are used to set the CPs. High state is achieved by placing a jumper between the top two pins of the header and the middle state is achieved by placing a jumper between the bottom two pins. Low state is simply achieved by using no jumper at all. Figure 9 illustrates how one could set the CPs for a QLx4600-S30 Series IC boost value of 21 (H, M, L) on Channel 1 and a boost of 16 (H, L, L) on Channel 2. FIGURE 9.

To address this, Intersil has developed its groundbreaking Q:ACTIVE™ product line. By integrating its analog ICs inside cabling interconnects, Intersil is able to achieve unsurpassed improvements in reach, power consumption, latency and cable gauge size as well as increased airflow in tomorrow’s datacenters. This technology transforms passive cabling into intelligent “roadways” that yield lower operating expenses and capital expenditures for the expanding data center. VENKEL LABEL, TO RENAME BOARD INTERSIL LABEL-SERIAL #, LINE 1 = YRWK/REV#/SN; LINE 2 = BOM NAME INTERSIL Intersil lane extenders allow greater reach over existing cabling while reducing the need for thicker cables. This significantly reduces cable weight and clutter, increases airflow and improves power consumption.
