DESCRIPTION

■ 1.9ns typical propagation delay

■ 275MHz f

(Clock)

MAX

The SY100EPT21L is a single, differential LVPECL-

to-LVTTL translator using a single +3.3V power supply.

Because low voltage positive ECL (LVPECL) levels are

used, only +3.3V and ground are required. The small

outline 8-pin SOIC package and low-skew, single-gate

design make the EPT21L ideal for applications that

require the translation of a clock or data signal where

minimal space, low power, and low cost are critical.

■ Differential LVPECL inputs

■ 24mA LVTTL output

■ Flow-through pinout

■ Q output will default LOW with inputs open

■ V output

■ Available in 8-pin MSOP and SOIC packages

allows a differential, single-ended, or AC-coupled

interface to the device. If used, the V output should be

bypassed to V

with 0.01µF capacitor.

Under open input conditions, the /D will be biased at a

/2 voltage level and the D input will be pulled to

ground. This condition will force the Q output low to

provide added stability.

APPLICATIONS

The 100EPT is compatible with positive ECL 100K

logic levels. For applications that require the smallest

footprint, consider the SY89321L in an ultra-small

(2mm × 2mm) 8-pin MLF™ package.

All support documentation can be found on Micrel’s web

site at: www.micrel.com.

■ ASIC/FPGA interface

■ Legacy interface

■ Precision differential-to-general purpose, single-

ended translation
