Ruggedized Quad SAS/SATA Redriver/Equalizer
with Extended Operating Temperature
MAX14980
General Description
Benefits and Features
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.
● High Performance Solution Designed to Overcome
Lossy Channels
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.
• 3dB of Independent (per Channel) Selectable
Input EQ and Output Preemphasis
• Compensates up to 30in of Channel Losses with
Deterministic Jitter: 23psP-P (max); Random Jitter:
1.8psRMS (max)
• 8dB (typ) of Return Loss Up to 3.0GHz
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.
• 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
● Designed to Reliably Operate in Harsh Environments
● Ease of Design and Layout

Note 2: All devices are 100% production tested at TA = +85°C. All temperature limits are guaranteed by design.
Note 3: Guaranteed by design.
Note 4: EQ (input equalization) as employed in this device refers to the equivalent of adding preemphasis before the input. For
example, input EQ of 3dB would show the same waveform as output PE of 3dB (see Figure 1).

MAX14980
Ruggedized Quad SAS/SATA Redriver/Equalizer
with Extended Operating Temperature
Detailed Description
The MAX14980 consists of four identical redrivers with
input equalization and output preemphasis useful for SAS
or SATA signals up to 6.0GT/s.
Input/Output Terminations
Inputs and outputs are internally 50Ω terminated to VCC
(see the Functional Diagram) and must be AC-coupled
using 12nF (max) capacitors to the SAS/SATA controller
IC and SAS/SATA device for proper operation.
Enable Inputs (ENA, ENB)
The MAX14980 features two active-high enable inputs
(ENA, ENB). ENA and ENB have internal pulldown resistors of 70kΩ (typ). When ENA or ENB is driven low or
left unconnected, the A or B channels enter low-power
standby mode and the redrivers are disabled.
Drive ENA or ENB high to place channel A or B in normal
operation (see Table 1).
Out-of-Band Threshold Selector
(MODEA, MODEB)
The MAX14980 provides full OOB signal support through
high-speed amplitude detection circuitry. OOB differential input signals less than the internal OOB threshold
(VSQ-DIFF) are detected as off and not passed to the
output. This prevents the system from responding to
unwanted noise. OOB differential input signals higher
than VSQ-DIFF are detected as on and passed to the
output, allowing OOB signals to transmit through the
MAX14980. The logic level of the MODE inputs sets
VSQ-DIFF for either SAS or SATA OOB signals (see Table
2). MODEA and MODEB have internal pulldown resistors
of 70kΩ (typ).

MAX14980
Ruggedized Quad SAS/SATA Redriver/Equalizer
with Extended Operating Temperature
Input Equalization (EQ0A, EQ1A, EQ0B, EQ1B)
The MAX14980 features control logic inputs (EQ0A,
EQ1A, EQ0B, EQ1B) to enable input equalization on
each channel, providing 3dB of boost (see Note 4 in
the Electrical Characteristics table). Drive EQ_ high to
enable input equalization. Drive EQ_ low to disable input
equalization (see Table 3). EQ0A, EQ1A, EQ0B, and
EQ1B have internal pulldown resistors of 70kΩ (typ).
Output Preemphasis (PE0A, PE1A, PE0B, PE1B)
The MAX14980 features control logic inputs (PE0A,
PE1A, PE0B, PE1B) to enable output preemphasis on
either channel, providing 3dB of boost. The MAX14980
true preemphasis, the transition signal, is increased after
a changing bit, thus increasing the total energy content
of the signal when employed. Drive PE_ high to enable
output preemphasis. Drive PE_ low to disable output preemphasis (see Table 4). PE0A, PE1A, PE0B, and PE1B
have internal pulldown resistors of 70kΩ (typ).

Applications Information
Exposed Pad Package
The exposed pad, 42-pin TQFN package incorporates
features that provide a very low thermal resistance path
for heat removal from the IC. The exposed pad on the
MAX14980 must be soldered to GND for proper thermal
and electrical performance. For more information on
exposed paddle packages, refer to Maxim Application
Note HFAN-08.1: Thermal Considerations of QFN and
Other Exposed-Paddle Packages.
Layout
Use controlled-impedance transmission lines to interface
with high-speed inputs and outputs of the MAX14980.
Place 2.2µF and 0.01µF power-supply bypass capacitors
as close as possible to VCC, recommended on each VCC
pin.
Power-Supply Sequencing
Caution: Do not exceed the absolute maximum ratings because stresses beyond the listed ratings can
cause permanent damage to the device.
Proper power-supply sequencing is recommended for all
devices. Always apply VCC before applying signals, especially if the signal is not current limited.
