Low-Jitter, 800Mbps, 10-Port LVDS
Repeaters with 100Ω Drive
Ultra-low 90psp-p (max) added deterministic jitter and
1psRMS (max) added random jitter ensure reliable communication in high-speed links that are highly sensitive to
timing error, especially those incorporating clock-anddata recovery or serializers and deserializers. The highspeed switching performance guarantees 800Mbps data
rate and less than 60ps (max) skew between channels
while operating from a single +3.3V supply.
Supply current at 800Mbps is 118mA and reduces to
2µA in power-down mode. LVDS inputs and outputs conform to the ANSI/EIA/TIA -644 standard. A fail-safe feature on the MAX9153 sets the output high when the input
is undriven and open, terminated, or shorted. The
MAX9153/MAX9154 are available in a 28-pin TSSOP
package and are specified for the -40°C to +85°C
extended temperature range.
Refer to the MAX9150 data sheet for a pin-compatible
10-port LVDS repeater capable of driving a double-terminated (50Ω) LVDS link.

MAX9153/MAX9154
General Description
The MAX9153/MAX9154 low-jitter, low-voltage differential
signaling (LVDS) repeaters are ideal for applications that
require high-speed data or clock distribution while minimizing power, space, and noise. The devices accept a
single LVDS input (MAX9153) or single LVPECL input
(MAX9154) and repeat the signal at 10 LVDS outputs.
Each differential output drives 100Ω, allowing point-topoint distribution of signals on transmission lines with
100Ω termination at the receiver input.

LVDS (MAX9153) or LVPECL (MAX9154) Differential Inputs. RIN+ and RIN- are

Differential LVDS Outputs
Power Down. Drive PWRDN low to disable all outputs and reduce supply current

Detailed Description
LVDS is a signaling method for point-to-point data communication over a controlled-impedance medium as
defined by the ANSI/TIA/EIA-644 and IEEE 1596.3 standards. LVDS uses a lower voltage swing than other
common communication standards, achieving higher
data rates with reduced power consumption, while
reducing EMI emissions and system susceptibility to
noise.
The MAX9153/MAX9154 are 800Mbps, 10-port
repeaters for high-speed, point-to-point, low-power
6
applications. The MAX9153 accepts an LVDS input and
has a fail-safe input circuit. The MAX9154 accepts an
LVPECL input. Both devices repeat the input at 10 LVDS
outputs. The devices detect differential signals as low
as 50mV and as high as 1.2V within the 0 to 2.4V input
voltage range as specified in the LVDS standards.
The MAX9153/MAX9154 outputs use a current-steering
configuration to generate a 2.5mA to 4.5mA output current. This current-steering approach induces less
ground bounce and no shoot-through current, enhancing noise margin and system speed performance. The
outputs are short-circuit current limited and are high
_______________________________________________________________________________________
Low-Jitter, 800Mbps, 10-Port LVDS
Repeaters with 100Ω Drive
The MAX9153/MAX9154 current-steering output
requires a resistive load to terminate the signal and
complete the transmission loop. Because the devices
switch the direction of current flow and not voltage levels, the output voltage swing is determined by the value
of the termination resistor multiplied by the output current. With a typical 3.8mA output current, the
MAX9153/MAX9154 produce a 380mV output voltage
when driving a transmission line terminated with a 100Ω
resistor (3.8mA x 100Ω = 380mV). Logic states are
determined by the direction of current flow through the
termination resistor.

device is not powered. The outputs have a typical differential resistance of 238Ω. The internal differential
output resistance terminates induced noise and reflections from the primary termination located at the LVDS
receiver.

Fail-Safe
The fail-safe feature of the MAX9153 sets the outputs
high when the differential input is:
• Open
•
Undriven and shorted
•
Undriven and terminated
Without a fail-safe circuit, when the input is undriven,
noise at the input may switch the outputs and it may
appear to the system that data is being sent. Open or
undriven terminated input conditions can occur when a
cable is disconnected or cut, or when an LVDS driver
output is in high impedance. A shorted input can occur
because of a cable failure.
When the input is driven with signals meeting the LVDS
standard, the input common-mode voltage is less than
VCC - 0.3V and the fail-safe circuit is not activated. If

the input is open, undriven and shorted, or undriven
and parallel terminated, an internal resistor in the failsafe circuit pulls both inputs above VCC - 0.3V, activating the fail-safe circuit and forcing the outputs high
(Figure 1).
The MAX9154 is essentially the MAX9153 without the
fail-safe circuit. The MAX9154 accepts input voltages
from 0 to VCC (vs. 0 to 2.4V for the MAX9153), which
allows interfacing to LVPECL input signals while retaining a good common-mode tolerance.

Supply Bypassing
Bypass each VCC with high-frequency surface-mount

Traces, Cables, and Connectors
The characteristics of input and output connections
affect the performance of the MAX9153/MAX9154. Use
controlled-impedance traces, cables, and connectors
with matched characteristic impedance.
Ensure that noise couples as common mode by running the traces of a differential pair close together.
Reduce within-pair skew by matching the electrical
length of the traces of a differential pair. Excessive
skew can result in a degradation of magnetic field cancellation. Maintain the distance between traces of a differential pair to avoid discontinuities in differential
impedance. Minimize the number of vias to further prevent impedance discontinuities.
Avoid the use of unbalanced cables, such as ribbon
cable. Balanced cables, such as twisted pair, offer
superior signal quality and tend to generate less EMI
due to canceling effects. Balanced cables tend to pick
up noise as common mode, which is rejected by the
LVDS receiver.
Termination
The MAX9153/MAX9154 are specified for 100Ω differential characteristic impedance but can operate with
90Ω to 132Ω to accommodate various types of interconnect. The termination resistor should match the differential characteristic impedance of the interconnect
and be located close to the LVDS receiver input. Use a
±1% surface-mount termination resistor.
The output voltage swing is determined by the value of the
termination resistor multiplied by the output current. With a
typical 3.8mA output current, the MAX9153/MAX9154 produce a 380mV output voltage when driving a transmission
line terminated with a 100Ω resistor (3.8mA x 100Ω =
380mV).
