28G – Linear PAM4 VCSEL Driver

Short-Form Datasheet

Description

Features

The HXT14400 is a quad-channel, low power,

Linear PAM4 VCSEL driver for SR optical

applications that supports signaling rates up to

28Gbaud or 56Gbps PAM4. In conjunction with

an individual DFB laser diode, the device handles

the complete digital-to-optical conversion,

including CML input with equalization, laser

driver, drive control and supervision.

• 230mW per channel power dissipation typical

• Supports up to: I_MOD= 12mA_PPand I_BIAS= 12mA

with V_CC= 3.3V

• Integrated 12-bit ADC with 6 channel analog

multiplexor front-end

• Programmable 8-bit Laser Modulation and

Bias current control

• Integrated Bias Monitor, Transmit and

Receive Power Monitor capability

• Automatic Power Control (APC)

• Programmable input LOS and squelch

function with disable, transmit disable, and

transmit fault indication

• Programmable input CTLE equalization

• Integrated temperature sensor and input for

external module temperature sensor

• Interrupts with user selectable mask control

• Input polarity inversion

The HXT14400 also integrates a number of

functions required for Automatic Power Control

(APC), as well as internal and module

temperature measurements and reporting.

Using the included RSSI input, the module

receive optical power can also be measured and

reported.

Designed for direct DC-coupled die in TOSA

applications with a small number of additional

components for cost-effective and compact

assemblies. Available in die form.

• Laser disable for I_MODand I_BIAS

• Integrated OTP for calibration

Typical Applications

• 2-wire interface control

• 200G QSFP56 Ethernet modules for

datacenter application

• 400G CFP8 Ethernet SR16

• Fiber channel modules

• Infiniband EDR optical modules
