Overview

High Performance Solution Designed to Overcome Lossy Channels
- 3dB of Independent (per Channel) Selectable Input EQ and Output Preemphasis
- Compensates up to 30in of Channel Losses with Deterministic Jitter: 23ps_P-P (max); Random Jitter: 1.8ps_RMS (max)
- 8dB (typ) of Return Loss Up to 3.0GHz
Designed to Reliably Operate in Harsh Environments
- Industrial Temperature Rated: -40°C to +85°C
- ±2.5kV Human Body Model (HBM) ESD Protection on All Pins
- Housed in a Flow-Through (42-Pin, 3.5mm x 9.0mm) TQFN Package or Resistance to Vibration/Shocks
Ease of Design and Layout
- Single 3.3V Operation
- Internal Input/Output 50Ω Termination Resistors

The MAX14980 quad-channel redriver is designed to redrive two full lanes of SAS or SATA signals up to 6.0GT/s (gigatransfers per second) and operates from a single +3.3V supply.

The MAX14980 features independent input equalization and output preemphasis. It enhances signal integrity at the receiver by equalizing the signal at the input and establishing preemphasis at the output of the device. SAS and SATA OOB (out-of-band) signaling is supported using high-speed amplitude detection on the inputs and squelch on the corresponding outputs. Inputs and outputs are all internally 50Ω terminated and must be AC-coupled to the SAS/SATA controller IC and SAS/SATA device.

The MAX14980 is available in a small 42-pin, 3.5mm x 9mm, TQFN package with flow-through traces for ease of layout. This device is specified over the -40°C to +85°C extended operating temperature range.
