The second is through the Advanced User Interface window shown in Figure 6. The Advanced User Interface window is available by selecting the Option | Interface (Advanced User) menu item and allows execution of serial commands manually. The Advanced User Interface window can also be used as a debug tool because it is capable of manually reading and writing to every register of the MAX9979. Detailed Description of Hardware The MAX9979 evaluation kit (EV kit) is a fully assembled and tested PCB that evaluates the MAX9979 dual PEIC with PMU. The EV kit includes SMA connections for the high-speed digital I/Os and the MAX9979 pin driver outputs. The MAX9979 EV kit is connected to the computer through the universal serial bus (USB) port. Power Supplies Connect the power supplies using the high-current banana jacks, J22 (-4.75V) and J23 (17.5V). Common for all the power supplies should be the GND banana jack on the MAX9979 EV kit. All power supplies should be within the range specified in the MAX9979 IC data sheet. The MAX9979 needs only two supplies to be attached to the board; all other supplies are generated through regulators on the EV kit board. _______________________________________________________________________________________ 9 Evaluates: MAX9979 MAX9979 Evaluation Kit High-Speed Digital I/Os The top edge and the bottom edge of the PCB are populated with end-launch SMA connectors, and are the high-speed digital I/Os of the MAX9979. The inputs are terminated internally to the MAX9979 IC. The outputs require termination (nominally 50) at the end of the attached cable. The board power supply (VTRM) is the voltage used to terminate the comparator outputs on the MAX9979 IC. Setting VTRM to +1.2V makes the high-speed digital I/Os compatible with LVDS levels. The high-speed digital inputs (DATA0/NDATA0, RCV0/NRCV0, DATA1/NDATA1, and RCV1/NRCV1) are intended for use with a high-speed differential signal source such as LVDS, LVPECL, ECL, etc. If only a singleended stimulus source is available, a converter consisting of a 1:1 ratio transformer (balun) can be used to produce a differential pair of inputs for DATA0/NDATA0 or DATA1/NDATA1. A three-resistor network can be used to produce a differential logic level for RCV0/NRCV0 or RCV1/NRCV1 inputs. The high-speed digital outputs (CL0/NCL0, CH0/NCH0, CL1/NCL1, and CH1/NCH1) are intended for use with a high-speed differential logic analyzer. These outputs are internally pulled up to the VTRM voltage through internal 50 resistors. These outputs can be double terminated at the measurement source by external 50 resistors. Pin Driver Outputs The dual-pin driver outputs or DCLP IO pins (DUT0 and DUT1) are through end-launch SMA connectors on the right edge of the PCB. The outputs have a typical output impedance of 50, which can be adjusted by software. Test Points There are 23 test points on the EV kit to facilitate performance analysis and circuit modification. The test points are listed in Table 1. Table 1.

During operation, TP10 should be continuously monitored to ensure that the junction temperature does not exceed +150C, which corresponds with +4.2V. During normal operation, a voltage of 3V to 3.6V is typical. Jumper Settings Tables 2 and 3 provide a list for jumper settings. Table 2.
