SY100EL92

TRIPLE LVPECL-TO-PECL

OR PECL-TO-LVPECL TRANSLATOR

DESCRIPTION

FEATURES

■ 5V and 3.3V power supplies required

■ Also, supports LVPECL-to-PECL translation

■ 500ps propagation delays

The SY100EL92 is a triple LVPECL-to-PECL or PECL-

to-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-to-

LVPECL 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.

■ Fully differential design

■ Differential line receiver capability

■ Application note

■ Available in 20-pin SOIC package

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.

Notes:

1. Power supply requirements applies as indicated in the DC electrical characteristics tables.

2. Skew is measured between outputs under identical transitions.

3. Duty cycle skew is the difference between a TPLH and TPHL propagation delay through a device Common Mode Range.

4. Minimum input swing for which AC parameters are guaranteed. The device has a DC gain of ~40.
