Low-Power, Compact 2.5Gbps/2.7Gbps

Clock-Recovery and Data-Retiming IC

MX873A

General Description

Features

♦ Fully Integrated Clock Recovery and Data

The MAX3873A is a compact, low-power 2.488Gbps/

2.67Gbps clock-recovery and data-retiming IC for

SDH/SONET applications. The phase-locked loop (PLL)

recovers a synchronous clock signal from the serial NRZ

data input. The input data is then retimed by this recov-

ered clock, providing a clean data output. The MAX3873A

meets all SDH/SONET jitter specifications, does not

require an external reference clock to aid in frequency

acquisition, and provides excellent tolerance to both

deterministic and sinusoidal jitter. The MAX3873A pro-

vides a PLL loss-of-lock (LOL) output to indicate whether

the CDR is in lock. The recovered data and clock outputs

are CML with on-chip 50Ω back terminations on each line.

The clock output can be powered down if not used.

Retiming

♦ Power Dissipation: 260mW with +3.3V Supply

♦ Clock Jitter Generation: 5mUI

RMS

♦ Exceeds ANSI, ITU, and Bellcore SDH/SONET

Jitter Specifications

♦ Differential Input Range: 50mV

♦ Single +3.3V Power Supply

to 1.6V

P-P

♦ PLL Fast Track (FASTRACK) Mode Available

♦ Clock Output Can Be Disabled

♦ Input Data Rate: 2.488Gbps or 2.67Gbps

♦ Selectable Output Amplitude

The MAX3873A is implemented in Maxim’s second-gener-

ation SiGe process and consumes only 260mW at 3.3V

supply (output clock disabled, low output swing). The

device is available in a 4mm x 4mm 20-pin QFN

exposed-pad package and operates from -40°C to +85°C.

♦ Tolerates 2000 Consecutive Identical Digits

♦ Loss-of-Lock Indicator

♦ Differential CML Data and Clock Outputs

♦ Operating Temperature Range: -40°C to +85°C
