| 19-2738; Rev 0; 1/03 3.3V Single LVDS Driver/Receiver General Description The MAX9164 high-speed LVDS driver/receiver is designed specifically for low-power point-to-point applications. The MAX9164 operates from a single 3.3V power supply, and is pin compatible with DS90LV019. The device features an independent differential driver and receiver. The MAX9164 driver output uses a current-steering configuration to generate a 3.1mA drive current. The driver accepts a single-ended input and translates it to LVDS signals at speeds up to 200Mbps over controlled-impedance media of approximately 100. The transmission media may be printed circuit board traces or cables. The enable logic input, DE, is used to enable or disable the driver. The MAX9164 receiver detects a differential input as low as 100mV and translates it to single-ended output at speeds up to 200Mbps. The enable logic input, RE, is used to enable or disable the receiver. Inputs and outputs conform to the ANSI TIA/EIA-644 LVDS standard. The MAX9164 is offered in 14-lead SO and TSSOP packages, and is specified for operation from -40C to +85C. o 3.3V Operation o 35% Lower Power than DS90LV019 o 200Mbps Data Signaling Rate o 1V Common-Mode Range o 100mV Receiver Sensitivity o Flow-Through Pinout o Receiver Output High for Open Input Features MAX9164 Ordering Information PART MAX9164ESD MAX9164EUD TEMP RANGE -40C to +85C -40C to +85C PIN-PACKAGE 14 SO 14 TSSOP Pin Configuration TOP VIEW DE 1 DIN N.C. 2 3 14 VCC 13 N.C. 12 DO+ Applications Cell-Phone Base Stations Add/Drop Muxes Digital Cross-Connects DSLAMs Network Switches/Routers Backplane Interconnect Clock Distribution ROUT 4 N.C. 5 N.C. 6 GND 7 MAX9164 11 DO10 RI+ 9 8 RIRE SO/TSSOP Typical Application Circuit MAX9164 DIN DE ROUT RE TABLE 1.

The MAX9164 operates from a single 3.3V power supply, and is pin compatible with the DS90LV019. The device features an independent differential driver and receiver. The MAX9164 driver outputs use a current-steering configuration to generate a 3.1mA (typ) output current. This current-steering approach induces less ground bounce and no shoot-through current, enhancing noise margin and system speed performance. The outputs are short-circuit current limited. The MAX9164 output requires a resistive load to terminate the signal and complete the transmission loop. With a typical 3.1mA output current, the MAX9164 produces a 310mV output voltage when driving a bus terminated with a 100 resistor (3.1mA x 100 = 310mV). The MAX9164 receiver detects a differential input as low as 100mV and translates it to single-ended output. The device features input biasing that drives the output high if the inputs are left open. The differential output requires a termination resistor at the far end of the transmission line. This termination resistor should match the differential impedance of the output transmission line. These termination resistors are typically 100. Minimize the distance between the input termination resistor and the MAX9164 receiver input. Traces, Cables, and Connectors The characteristics of differential input and output connections affect the performance of the device. Use controlled-impedance traces, cables, and connectors with matched characteristic impedance. Ensure that noise couples as common mode by running the traces of a differential pair close together. Reduce within-pair skew by matching the electrical length of the conductors within a differential pair. Excessive skew can result in a degradation of magnetic field cancellation. Maintain the distance between conductors within a differential pair to avoid discontinuities in differential impedance. Minimize the number of vias to further prevent impedance discontinuities. Power-On Reset The power-on reset voltage of the MAX9164 is typically 2.2V. When the supply falls below this voltage, the device is disabled and the outputs (DO+, DO-, and ROUT) are high impedance. Board Layout For LVDS applications, a four-layer PC board with separate power, ground, LVDS, and logic signal layers is recommended. Separate the LVTTL/LVCMOS and LVDS signals to prevent coupling. Applications Information Power-Supply Bypassing Bypass V CC with high-frequency, surface-mount ceramic 0.1F and 0.001F capacitors in parallel as close to the device as possible, with the smaller valued capacitor closest to VCC. TRANSISTOR COUNT: 901 PROCESS: CMOS Chip Information Termination The MAX9164 requires an external termination resistor at the differential input. This termination resistor should match the differential impedance of the input transmission line. 8 _______________________________________________________________________________________ 3.3V Single LVDS Driver/Receiver Package Information (The package drawing(s) in this data sheet may not reflect the most current specifications.
