Quick Start The MAX9360 EV kit is a fully assembled and tested surface-mount board. The EV kit contains two independent LVTTL/CMOS-to-LVECL translators with different packages: an 8-pin SO package (upper circuit) and an 8-pin SOT23 package (lower circuit).

The EV kit includes two MAX9360s with different packages. The MAX9360 is a low-skew, single LVTTL/ CMOS-to-differential LVECL/ECL translator. The EV kit accepts an LVTTL/TTL/CMOS input signal and converts it to a differential LVECL/ECL signal at frequencies up to 1GHz. The MAX9360 EV kit is a four-layer PC board with 50Ω controlled-impedance traces. It can also be used to evaluate the MAX9361, a TTL/CMOS-to-differential LVECL/ECL translator. Evaluates: MAX9360/MAX9361 MAX9360 Evaluation Kit • Two matched SMA-to-SMA 50Ω coax cables for outputs: Q1 and Q1 (or Q2 and Q2) • One SMA-to-SMA 50Ω coax cable for input (should be less than 6in long): D1/D2 • One SMA-to-SMA 50Ω coax cable for triggering connection Evaluating the MAX9360 on Either Upper or Lower Circuit Do not turn on the power supplies until all connections are completed: 1) Connect two matched output coax cables to the oscilloscope. Then connect the other end of the cables to Q1 and Q1/(Q2 and Q2). 2) Connect the input coax cable to D1/D2. Connect the other end to one of the positive outputs from the signal generator with the following setting: a) Frequency = 1GHz b) VIH = 2.0V, VIL = 1.4V c) Duty cycle = 50% 3) Connect one coax cable to the trigger output of the signal generator. Connect the other end to trigger the input of the oscilloscope. 4) Connect a 2.000V power supply to the VGG1/VGG2 pad. Connect the supply ground to the GND pad closest to VGG1/VGG2. 5) Connect a +5.3V power supply to the VCC1/VCC2 pad. Connect the supply ground to the GND pad closest to VCC1/VCC2. 6) Connect a -1.3V power supply to the VEE1/VEE2 pad. Connect the supply ground to the GND pad closest to VEE1/VEE2. Note: VGG1/VGG2 is an additional power supply to shift up the system voltage by 2V. In the real application, VGG1/VGG2 can be eliminated. Since the EV kit is shifted up 2V, VOH and VOL ranges are also shifted accordingly. Detailed Description The MAX9360 EV kit contains two low-skew, high-speed single LVTTL/CMOS-to-differential LVECL translators with different packages. Each circuit has independent power supplies preventing noise injection from one to the other. In order to terminate outputs with 50Ω to -2V using the 50Ω oscilloscope termination, an extra power supply (VGG1/VGG2) is added to shift the system by 2V. The LVTTL/TTL/CMOS logic inputs are referred to 2V. Input Signal The MAX9360 EV kit can accept a maximum 1GHz LVTTL/TTL/CMOS signal. Since the circuit is shifted by 2.0V, the new input high level is 4V, and the input low level is 2.8V. Input termination resistors could be added for optimum performance. Note that there is no provision on the EV kit for input termination. Set the signal generator output levels to half the magnitudes given above for use without input termination. Supply Range Table 1 shows the VCC and VEE ranges for the corresponding logic type. Evaluating the MAX9361 To evaluate the MAX9361, replace the MAX9360ESA/ MAX9360UKA (top mark AAJI) with the MAX9361ESA/ MAX9361EKA (top mark AAJJ), and adjust the VCC supply (refer to the MAX9360/MAX9361 data sheet). 7) Turn on the power supply, enable the pulse generator, and verify the single-ended output: a) Frequency = 1GHz b) VOH: 0.855V to 1.115V c) VOL: 0.065V to 0.375V d) VOD ≥ 550mV Table 1.
