2.5GHz ANY DIFF. IN-TO-LVPECL

PROGRAMMABLE CLOCK DIVIDER/

Micrel, Inc.

SY89874U

FANOUT BUFFER WITH INTERNAL TERMINATION

FEATURES

■ Integrated programmable clock divider and 1:2

fanout buffer

Precision Edge

■ Guaranteed AC performance over temperature and

voltage:

• > 2.5GHz f

DESCRIPTION

MAX

• < 250ps t /t

• < 15ps within device skew

This low-skew, low-jitter device is capable of accepting a

high-speed (e.g., 622MHz or higher) CML, LVPECL, LVDS or

HSTL clock input signal and dividing down the frequency

using a programmable divider ratio to create a frequency-

locked, lower speed version of the input clock. Available divider

ratios are 2, 4, 8 and 16, or straight pass-through. In a typical

622MHz clock system this would provide availability of

311MHz, 155MHz, 77MHz or 38MHz auxiliary clock

components.

r f

■ Low jitter design:

• < 10ps total jitter

• < 1ps

cycle-to-cycle jitter

RMS

■ Unique input termination and V pin for DC-coupled

and AC-coupled Inputs; CML, PECL, LVDS and

HSTL

■ TTL/CMOS inputs for select and reset

■ 100k EP compatible LVPECL outputs

■ Parallel programming capability

■ Programmable divider ratios of 1, 2, 4, 8 and 16

■ Low voltage operation 2.5V or 3.3V

■ Output disable function

The differential input buffer has a unique internal termination

design that allows access to the termination network through

a V pin. This feature allows the device to easily interface to

different logic standards. A V

AC-coupled applications.

reference is included for

REF-AC

The /RESET input asynchronously resets the divider. In

the pass-through function (divide by 1) the /RESET

synchronously enables or disables the outputs on the next

falling edge of IN (rising edge of /N).

■ –40°C to 85°C temperature range

■ Available in 16-pin (3mm × 3mm) MLF package

TYPICAL PERFORMANCE

APPLICATIONS

■ SONET/SDH line cards

■ Transponders

OC-12 to OC-3

Translator/Divider

■ High-end, multiprocessor sensors
