MAX14980 Ruggedized Quad SAS/SATA Redriver/Equalizer with Extended Operating Temperature General Description Benefits and Features The MAX14980 quad-channel redriver is designed to High Performance Solution Designed to Overcome redrive two full lanes of SAS or SATA signals up to Lossy Channels 6.0GT/s (gigatransfers per second) and operates from a 3dB of Independent (per Channel) Selectable single +3.3V supply. Input EQ and Output Preemphasis The MAX14980 features independent input equalization Compensates up to 30in of Channel Losses with and output preemphasis. It enhances signal integrity at the Deterministic Jitter: 23ps (max) Random Jitter: P-P receiver by equalizing the signal at the input and establish- 1.8ps (max) RMS ing preemphasis at the output of the device. SAS and SATA 8dB (typ) of Return Loss Up to 3.0GHz OOB (out-of-band) signaling is supported using high-speed Designed to Reliably Operate in Harsh Environments amplitude detection on the inputs and squelch on the cor- responding outputs. Inputs and outputs are all internally Industrial Temperature Rated: -40C to +85C 50 terminated and must be AC-coupled to the SAS/SATA 2.5kV Human Body Model (HBM) ESD controller IC and SAS/SATA device. Protection on All Pins The MAX14980 is available in a small 42-pin, 3.5mm x Housed in a Flow-Through (42-Pin, 3.5mm x 9mm, TQFN package with flow-through traces for ease of 9.0mm) TQFN Package or Resistance to Vibration/ layout. This device is specified over the -40C to +85C Shocks extended operating temperature range.
