MAX3799ETJ+T Laser Driver IC 14Gbps 1 Channel 2.85V ~ 3.63V 32-TQFN (5x5)
The MAX3799ETJ+T is an integrated multirate limiting amplifier and VCSEL driver developed by Analog Devices (Maxim Integrated), housed in a 32-pin TQFN surface mount package, supporting data rates from 1Gbps up to 14Gbps. Powered by a single 3.3V supply ranging from 2.85V to 3.63V, this IC integrates a receiver limiting amplifier with loss-of-signal detection and a VCSEL transmitter driver with programmable modulation and bias current. It meets 1000BASE-SR and 10GBASE-SR optical communication standards, uses a three-wire digital interface for register configuration, works from -40°C to 85°C, and is optimized for compact SFP and SFP+ multi-source agreement optical transceiver modules in data center and storage networking systems.
Key Features
● Multirate operation covering 1Gbps to 14Gbps, fully compliant with 1000BASE-SR and 10GBASE-SR Ethernet specifications.
● Integrated limiting amplifier with LOS detection and VCSEL driver, combining transmitter and receiver functions within one chip.
● 3-wire serial digital interface for flexible configuration of modulation current, bias current, LOS threshold and signal deemphasis.
● Differential CML I/O with 50Ω on-chip termination to simplify high-speed PCB transmission line design.
● Built-in DACs for APC average optical power control and laser safety protection to avoid VCSEL damage.
● Low power consumption with typical 97mA supply current under normal operation for small form-factor optical modules.
FAQ
Q: What is the function of the 3-wire interface?
A: It configures transmitter and receiver parameters dynamically. Controlled impedance PCB routing is mandatory; maintain solid ground plane and minimize high-speed trace length to reduce signal attenuation and crosstalk.
Alternative transceiver ic models
1. MAX3798ETJ+T: Lower-rate integrated limiting amplifier and VCSEL driver with similar TQFN packaging for 10G SFP+ optical module designs with simplified register functions.
2. MAX3864ETG+: High-speed VCSEL driver paired with separate limiting amplifier, suitable for customized optical transceiver layouts requiring discrete signal chain design.
3. DS10CP154SQ: High-speed limiting amplifier without VCSEL driver, ideal for optical receiver-only designs that use independent laser driving circuits.
