QUINT LVPECL-TO-PECL

OR PECL-TO-LVPECL

TRANSLATOR

Micrel, Inc.

SY100E417

DESCRIPTION

FEATURES

■ 3.3V and 5V power supplies required

■ Also, supports LVPECL-to-PECL translation

■ 500ps propagation delays

The SY100E417 is a quint LVPECL-to-PECL translator.

It can also be used as a quint PECL-to-LVPECL translator.

The device receives standard PECL signals and translates

them to differential LVPECL output signals (or vice versa).

The SY100E417 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.

■ Fully differential design

■ Differential line receiver capability

■ Available in 28-pin PLCC package

A VBB output is provided for interfacing single ended

input signals. If a single ended input is to be used, the VBB

output should be connected to the Dn input and the active

signal will drive the Dn 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 SY100E417

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 SY100E417 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 SY100E417 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.

VCC_VBB = 3.3V is only required for single-ended LVPECL

input. For differential LVPECL input, VCC_VBB can be either

3.3V or 5.0V.

BLOCK DIAGRAM

Under open input conditions, the Dn input will be biased

at a VCC/2 voltage level and the Dn input will be pulled to

GND. This condition will force the "Qn" output low, ensuring

stability.
