1Gbps to 4.25Gbps Multirate VCSEL

Driver with Diagnostic Monitors

General Description

Features

The MAX3795 is a high-speed VCSEL driver for small-

form-factor (SFF) and small-form-factor pluggable (SFP)

fiber optic transmitters. It contains a bias generator, a

laser modulator, and comprehensive safety features.

The automatic power control (APC) adjusts the laser

bias current to maintain average optical power over

changes in temperature and laser properties. The dri-

ver accommodates common-cathode and differential

configurations.

♦ Supports All SFF-8472 Digital Diagnostics

♦ 3.3V ±±10 Singlꢀ Supplꢁ

♦ 2mA to ±5mA Modulation Currꢀnt

♦ ±mA to ±5mA Bias Currꢀnt

♦ 52ps Transition Timꢀ

♦ 8.4ps Dꢀtꢀrministic Jittꢀr

♦ Optional Pꢀaking Currꢀnt to Improvꢀ VCSEL Edgꢀ

The MAX3795 operates up to 4.25Gbps. It can switch

up to 15mA of laser modulation current and source up

to 15mA of bias current. Adjustable temperature com-

pensation is provided to keep the optical extinction

ratio within specifications over the operating tempera-

ture range. The MAX3795 interfaces with the Dallas

DS1856/DS1859 to meet SFF-8472 timing and diagnos-

tic requirements. The MAX3795 accommodates various

VCSEL packages, including low-cost TO-46 headers.

Spꢀꢀd

♦ Supports Common-Cathodꢀ and Diffꢀrꢀntial

Configuration

♦ Safꢀtꢁ Circuits Compliant with SFF and SFP

MSAs

♦ Pin Compatiblꢀ to MAX3741A

The MAX3795 safety circuit detects faults that could

cause hazardous light levels and disables the VCSEL

output. The safety circuits are compliant with SFF and

SFP multisource agreements (MSAs).

TEMP RANGE PIN-PACKAGE

The MAX3795 is available in a compact 4mm ✕ 4mm,

24-pin thin QFN package and operates over the -40°C

to +85°C temperature range. The MAX3795 is pin-for-

pin compatible with the MAX3740A and is available in

lead-free packages.
