MAX9374/MAX9374A 19-2326 Rev 0 1/02 Differential LVPECL-to-LVDS Translators General Description Features The MAX9374 and MAX9374A are 2.0GHz differential Guaranteed 2.0GHz Operating Frequency LVPECL-to-LVDS translators and are designed for tele- 250ps (typ) Propagation Delay com applications. They feature 250ps propagation delay. The differential output conforms to the ANSI 1.0ps RMS Jitter (typ) TIA/EIA-644 LVDS standard. The inputs are biased with 2.375V to 2.625V Low-Voltage Supply Range internal resistors such that the output is differential low when inputs are open. An on-chip V reference output (MAX9374) BB is available for single-ended operation. On-Chip V Reference for Single-Ended Input BB The MAX9374 is designed for low-voltage operation Output Low for Open Inputs from a 2.375V to 2.625V power supply for use in 2.5V systems. The MAX9374A is designed for 3.0V to 3.6V Output Conforms to ANSI TIA/EIA-644 LVDS operation in systems with a nominal 3.3V supply. Both Standard devices are offered in industry-standard 8-pin SOT23 ESD Protection >2.0kV (Human Body Model) and SO packages.
