MAX4952
Quad Equalized 1.5/3.0/6.0GT/s
SAS/SATA Redriver

______________________________________________________________________________________
Detailed Description
The MAX4952 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 50
Ω 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 MAX4952 features two active-high enable inputs
(ENA, ENB). ENA and ENB have internal pulldown
resistors of 70k
Ω (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 nor-
mal operation (see Table 1).
Out-of-Band Threshold Selector
(MODEA, MODEB)
The MAX4952 provides full OOB signal support through
high-speed amplitude detection circuitry. OOB differen-
tial 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
MAX4952. 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 70k
Ω (typ).
