Quick Start The MAX2160 EV kit is fully assembled and factory tested. Follow the instructions in the Connections and Setup section for proper device evaluation. Test Equipment Required • One power supply capable of supplying at least 500mA, +2.85V • One dual-output power supply capable of supplying at least 500mA at +3V and -3V • One RF signal generator capable of delivering at least 0dBm of output power at frequencies up to 1GHz • One RF spectrum analyzer capable of covering the operating frequency range of the device • A PC (486DX33 or better) with Windows® 95/98, 2000, NT 4.0 or later operating system, 64MB of memory, and an available parallel port • A 25-pin parallel cable • (Optional) One multichannel digital oscilloscope • (Optional) A network analyzer to measure return loss • (Optional) An ammeter to measure supply current Connections and Setup This section provides a step-by-step guide to testing the basic functionality of the EV kit. Do not turn on DC power or RF signal generators until all connections are completed: 1) Verify that all the desired jumpers are in place (see Table 1). 2) With its output disabled, set the DC power supply to +2.85V. Connect the power supply to the VCC (through an ammeter if desired) and GND terminals on the EV kit. If available, set the current limit to 75mA. 3) With its output disabled, set the dual-output DC power-supply voltages to +3V and -3V. Connect the +3V, -3V, and GND terminals of the power supply to jumpers J15, J17, and J16, respectively. If available, set the current limits to 50mA. 4) With its output disabled, set the RF signal generator to a 767.143MHz frequency and a -60dBm power level. Connect the output of the RF signal generator to J5 on the evaluation board. 5) Connect a 25-pin parallel cable between the PC’s parallel port and the MAX2160 evaluation board. 6) Turn on the ±3V power supply, followed by the +2.85V power supply. The supply current from the +2.85V supply should read approximately 44mA. Be sure to adjust the power supply to account for any voltage drop across the ammeter. 7) Adjust potentiometers R16 and R17 until the voltages at GC1 and GC2 are approximately 1.5V. 8) Install and run the MAX2160 control software. Software is available for download on the Maxim website at www.maxim-ic.com. 9) Load the default register settings from the control software by clicking the Defaults tab at the top of the screen. 10) Connect either the I or Q output to the spectrum analyzer, or connect both I and Q outputs to the oscilloscope. 11) Enable the RF signal generator’s output. 12) If using a spectrum analyzer, set the center frequency of the analyzer to 571kHz and a span of 100kHz. Set the reference level to 0dBm. Increase the input power of the signal generator until the output level reaches -2dBm. This is the nominal output level for the I and Q channels. The gain of the receiver can be calculated by taking the difference in dB between the input and output power.

Record this as the reference output level. 4) Adjust R16 until V GC1 = 2.7V, and record the change in the I/Q output levels in dB relative to -2dBm. This change in output power is the gaincontrol range of the RF stage. In addition, the ground returns for the VCO, VTUNE, and charge pump require special layout consideration. The VCOBYP capacitor (C37) and the VCCVCO bypass capacitor (C19) ground returns must be routed back to the GNDVCO pin and then connected to the overall ground plane at that point (GNDVCO). All loop filter component grounds (C27–C30) and the VCCCP bypass capacitor (C17) ground must all be routed together back to the GNDCP pin. GNDTUNE must also be routed back to the GNDCP pin along with all other grounds from the PLL loop filter. The GNDCP pin must then be connected to the overall ground plane. See Figures 2–6 for recommended board layout. Table 1. MAX2160 EV Kit Jumper Settings JUMPER 4) Adjust R17 until VGC2 = 2.7V, and record the change in the I/Q output levels in dB relative to -2dBm. This change in output power is the gain-control range of the baseband stage. 5) The baseband gain-control range will be at least 57dB. Layout Considerations JUMPER POSITION J6 OPEN: ENTCXO pin is controlled Sets control of by the PC software. the ENTCXO SHORT: ENTCXO pin is pulled low pin (remove R31 in this mode). J7 OPEN: GC2 is controlled with an external voltage source applied to Sets control of TP4 (remove R18 in this mode). the GC2 pin SHORT: GC2 is controlled by the voltage set by potentiometer R17.

Sets control of 2-3: GC1 is controlled by the RF the GC1 pin power-detector output (power detector must be enabled). 5) The RF gain-control range will be at least 38dB. Baseband Gain-Control Range (GC2) To measure the gain-control range in the baseband stage, follow the steps below: 1) Adjust R16 so VGC1 = 1.5V. 2) Adjust R17 so VGC2 = 0.3V. 3) Adjust the RF input power to achieve -2dBm at the I/Q outputs. Record this as the reference output level. FUNCTION The MAX2160 evaluation board can serve as a reference board layout. Keep traces carrying RF signals as short as possible to minimize radiation and insertion loss. Place supply-decoupling capacitors as close to the device as possible. Solder the package’s exposed paddle evenly to the board ground plane for a low-inductance ground connection and for improved thermal dissipation. _______________________________________________________________________________________ 3 Evaluates: MAX2160 If using an oscilloscope, observe the 571kHz sine wave. Increase the input power of the signal generator until the I and Q outputs reach 0.5VP-P. This is the nominal output level for the I and Q channels. The I and Q waveforms will be out-of-phase by approximately 90°. Voltage gain can be calculated by: Gain = 20 x LOG(VOUT_P-P / (2 x sqrt(2) x VIN_RMS) ) where VIN_RMS = √( 50 x 10[ (Pin (dBm) – 30) / 10] ) Evaluates: MAX2160 MAX2160 Evaluation Kit TP3 J10 J4 R21 5.6k Ω VCC9 1 2 J4-2 3 J4-3 4 J4-4 5 J4-5 C28 0.047uF 7 J4-7 8 J4-8 9 J4-9 C29 470pF C30 220pF C27 0.1uF C20 0.01uF J1 6 R20 1.2k Ω R24 10k Ω R19 OPEN R22 5.6k Ω 10 J4-10 C17 100pF C19 100pF 11 J4-11 VCC7 VCC6 J11 J12 12 13 R29 49.9 Ω C37 470nF 14 40 39 38 37 36 35 34 33 32 31 VCCP CPOUT TEST GNDTUNE VTUNE GNDVCO VCCVCO VCOBYP N.C 17 GNDCP 16 18 19 1 20 21 C1 0.01uF J2 22 2 C2 27pF 23 24 N.C TCXO Y1 16MHz 747238-4 J3 J9 3 XTAL 4 GNDXTAL 30 VCC5 C16 100pF 29 GNDBB 28 QOUT 27 R2 0Ω J4-2 C5 100pF U2-C 5 6 OUTA R23 10k Ω C22 0.01uF C3 VCC8 100pF U1 5 VCCXTAL 6 XTALOUT 7 VCCDIG 8 SDA C24 0.01uF U3 N.C VCCBB C4 100pF R3 OPEN -3V GNDBB 26 IOUT 25 N.C 24 GC2 23 V CC INA- OUTB INA+ INB- V INB+ EE R30 49.9 Ω C23 MAX4217EUA 0.01uF C21 0.01uF MAX2160 VCC9 +3V TP4 R1 0Ω R26 10k Ω J7 R10 4.7k Ω R7 0Ω RFIN SHDN N.C VCCLNA GC1 VCCMX PWRDET VCCFLT 14 15 16 17 18 19 20 VCC1 2 R33 0Ω VCC2 VCC3 VCC J13 J6 OPEN VCC2 J18 VCC3 J19 VCC4 J20 VCC5 J21 VCC6 J22 VCC7 J23 VCC8 J24 VCC9 J25 + C31 10uF C35 0.01uF J14 C10 100pF +3V TP2 3 2 1 R32 4.7k Ω U2-D J15 J27 +3V + C32 10uF C34 0.01uF J16 8 74LV07A R17 20k Ω C15 0.01uF VCC4 C9 100pF C8 100pF TP1 C38 0.01uF 74LV07A 9 C7 100pF R9 4.7k Ω U2-A +3V 21 VCC1 13 1 R18 0Ω 22 N.C R31 0Ω 74LV07A J4-5 ENTCXO U2-F 12 J4-4 LTC 0Ω 74LV07A J4-10 SCL 13 R12 4.7k Ω 4 9 10 C18 1000pF R8 U2-B 3 +3V VCCBIAS 74LV07A R6 J4-3 11 N.C R5 OPEN 0Ω R13 4.7k Ω U2-E 10 12 74LV07A R4 0Ω 11 R11 4.7k Ω J4-11 J5 C11 SHORT C12 100pF C6 1000pF R16 20k Ω C14 0.01uF + -3V C13 OPEN Figure 1.
