Micrel, Inc. SY100EL92 TRIPLE LVPECL-TO-PECL OR PECL-TO-LVPECL TRANSLATOR SY100EL92 DESCRIPTION FEATURES ■ 5V and 3.3V power supplies required The SY100EL92 is a triple LVPECL-to-PECL or PECLto-LVPECL translator. The device receives standard PECL signals and translates them to differential LVPECL output signals (or vice versa). SY100EL92 can also be used as a differential line receiver for PECL-to-PECL or LVPECL-toLVPECL signals. However, please note that for the latter we will need two different power supplies. Please refer to Function Table for more details. VBB outputs are provided for interfacing single ended input signals. If a single ended input is to be used, the VBB output should be connected to the D input and the active signal will drive the D input. When used, the VBB should be bypassed to VCC via a 0.01µF capacitor. The VBB is designed to act as a switching reference for the SY100EL92 under single ended input conditions. As a result, the pin can only source/sink 0.5mA of current. To accomplish the PECL-to-LVPECL level translation, the SY100EL92 requires three power rails. The VCC and VCC_VBB supply is to be connected to the standard PECL supply, the 3.3V supply is to be connected to the VCCO supply, and GND is connected to the system ground plane. Both the VCC and VCCO should be bypassed to ground with a 0.01µF capacitor. To accomplish the LVPECL-to-PECL level translation, the SY100EL92 requires three power rails as well. The 5.0V supply is connected to the VCC and VCCO pins, 3.3V supply is connected to the VCC_VBB pin and GND is connected to the system ground plane. VCC_VBB is used to provide a proper VBB output level if a single ended input is used. For differential LVPECL input VCC_VBB can be either 3.3V or 5V. Under open input conditions, the D input will be biased at a VCC/2 voltage level and the D input will be pulled to GND. This condition will force the "Q" output low, ensuring stability. ■ Also, supports LVPECL-to-PECL translation ■ 500ps propagation delays ■ Fully differential design ■ Differential line receiver capability ■ Application note ■ Available in 20-pin SOIC package PIN NAMES FUNCTION TABLE Function Vcc Vcco Vcc_VBB PECL-to-LVPECL 5.0V 3.3V 5.0V Dn PECL / LVPECL Inputs LVPECL-to-PECL 5.0V 5.0V 3.3V Qn PECL / LVPECL Outputs PECL-to-PECL 5.0V 5.0V 5.0V VBB PECL / LVPECL Reference Voltage Output LVPECL-to-LVPECL 5.0V 3.3V 3.3V VCCO VCC for Output M9999-031306 hbwhelp@micrel.com or (408) 955-1690 Pin Function VCC_VBB VCC for VBB Output GND Common Ground Rail VCC VCC for Internal Circuitry Rev.: G 1 1 Amendment: /0 Issue Date: March 2006 Micrel, Inc.
