The MAX9315 EV kit accepts one or two LVECL/LVPECL or HSTL differential inputs and reproduces the selected input at five differential outputs. The EV kit operates up to 1.5GHz. Inputs can be single ended by connecting the on-chip VBB reference to one side of a differential input. The MAX9315 EV kit can be modified to evaluate the MAX9316. The MAX9316 has one differential clock input and one single-ended input.

Quick Start The MAX9315 EV kit is fully assembled and tested. Do not turn on the power supplies until all connections are completed. Recommended Equipment • One 1.5GHz (min) differential signal generator (e.g., Agilent 8133A) • One 8GHz (min) bandwidth oscilloscope with internal 50Ω input termination (e.g., Tektronix 11801C digital sampling oscilloscope with SD-24 sampling head) • Two power supplies a) One 2V ± 0.05V with 500mA current capability b)One adjustable -1.8V to -0.375V with 500mA current capability • Matched male-SMA-to-male-SMA 50Ω coax cables a) Matched SMA 50Ω coax cables for input CLK0 and CLK0 b)Matched SMA 50Ω coax cables for output Q0 and Q0 Evaluating the MAX9315 with One Differential Input 1) Verify that shunts are across pins 2 and 3 of jumper JU1 (EN), and pins 2 and 3 of jumper JU2 (CLKSEL). 2) Connect two matched coax cables to the oscilloscope. Connect the other end of the cables to Q0 and Q0 on the EV kit board. 3) Connect a 2.0V power supply to the VCC pad. Connect the supply ground to the GND pad closest to VCC. 4) Connect a -1.3V adjustable power supply to the pad labeled VEE. Connect the supply ground to the GND pad closest to VEE. 5) Adjust the differential signal generator to the following settings: a) VIH = 1.0V b) VIL = 0.3V c) Duty cycle = 50% d) Frequency = 1.5GHz 6) Connect one pair of matched coax cables to the differential signal generator. Connect the other end of the cables to CLK0 and CLK0 on the EV kit. 7) Turn on the power supplies, enable the generator, and verify that the output signals meet the following specifications: a) VOH: 0.855V < VOH < 1.135V b)VOL: 0.055V < VOL < 0.305V c) VOH - VOL: 550mV < (VOH - VOL) < 910mV Notes: 1) To verify output signals other than Q0 and Q0, remove the corresponding 50Ω output termination resistor, and make sure the untested output signals are terminated with 50Ω resistors. 2) For other input levels, refer to the MAX9315 and MAX9316 data sheets, setting VCC = 2.0V. 3) To evaluate the MAX9316, see the Evaluating the MAX9316 section. 2 _______________________________________________________________________________________ MAX9315 Evaluation Kit Power Supply In order to terminate outputs with 50Ω to (VCC - 2V) using the 50Ω oscilloscope input, VCC is set to 2.0V. In an actual application, VCC and VEE can have different supplies; refer to the MAX9315 and MAX9316 data sheets. VBB is an on-chip reference output voltage. Connect VBB to the inverting or noninverting clock input to provide a reference for single-ended operation. For VCC = 2.0V, the MAX9315 EV kit provides a VBB from 0.475V to 0.675V. Enable The MAX9315 EV kit features a DC logic-level EN function using jumper JU1. Table 1 shows the EN settings and its corresponding functions. Clock Select Input CLKSEL pin selects channel 0 (CLK0 and CLK0) or channel 1 (CLK1 and CLK1). The MAX9315 EV kit can either provide an internal DC select signal by using jumper JU2, or accept an AC external signal from an SMA connector CLKSEL. (Before connecting the external signal to the CLKSEL connector, verify there is no shunt across jumper JU2). Table 2 shows the functions of jumper JU2. Evaluating the MAX9316 The MAX9315 EV kit can also be used to evaluate the MAX9316, which has one differential LVECL/LVPECL, HSTL input, or single-ended input for scan clock. To evaluate the MAX9316, the following modifications have to be made: 1) Replace the MAX9315EUP with the MAX9316EUP. 2) Remove R19, R20, and C8. 3) Add 100Ω resistors on R11 and R12 and a 0.01µF capacitor on C10.
