LXP600A, LXP602 and LXP604

Low Jitter Clock Adapters (CLADs)

General Description

The LXP600A, LXP602 and LXP604 Clock Adapters

(CLADs) incorporate Level One’s patented frequency

conversion circuitry. The LXP600A and LXP602 convert

a 1.544 MHz input clock to a 2.048 MHz output clock, or

vice versa. The LXP604 converts between 1.544 MHz and

4.096 MHz. Each CLAD produces two different high

frequency output (HFO) clocks for applications which

require a higher-than-baud rate backplane or system clock.

Level One’s patented locking method enables the CLAD to

perform frequency conversion with no external

components, while generating very little jitter on the output

clock. The conversion is digitally controlled so the output

clock (CLKO) is as accurate as the input clock (CLKI), and

the two clocks are frequency-locked together. When an

input frame sync pulse (FSI) is provided, the CLAD also

phase-locks CLKI and CLKO together, and locks the

output frame sync pulse (FSO) to FSI.

Revision 1.1

Features

• Generates a 1.544 MHz clock and its frame sync from

a 2.048 MHz or 4.096 MHz clock and its frame sync,

or vice versa

• Low output jitter meets AT&T Publication 62411 for

1.544 MHz, and ITU Recommendation G.823 for

2.048 MHz

• Digital control of frequency conversion process

• No external components

• Available in 8-pin plastic DIP and 16-pin SOIC

• Pin-selectable operation mode

• Advanced CMOS device requires only a single +5 V

power supply

Applications

• Internal timing system for Channel Banks, Digital

Loop Carriers, Multiplexers, Internal Timing

Generators, PBX, etc.

• Conversion between 2.048 MHz or 4.096 MHz

backplane rates and 1.544 MHz T1 clock rate

• Conversion between North American

International standards (T1/E1 Converter)

and
