LTC6955/LTC6955-1: Ultralow Jitter 11 Output Fanout Buffer
Analog Devices Inc.Demonstration Circuit 2611A features the LTC6955, Ultralow Jitter 11 Output Fanout Buffers.
By default, the DC2611A is powered from a single 3.3V supply. An option is provided to power to the DC2611A from dual supplies, allowing for the LTC6955’s output supply pins to connect to an LTC Silent Switcher® and the LTC6955 input supply pin to connect to a low noise LDO.
The differential inputs and six of the differential outputs are populated with 0.5" spaced SMA connectors. These outputs are AC-coupled with 50Ω transmission lines making them suitable to drive 50Ω impedance instruments. All registered trademarks and trademarks are the property of their respective owners.
The remaining four differential outputs are terminated with 100Ω.
A calibration path is provided to aid in accurate LTC6955 propagation delay measurements. The calibration path can be also reconfigured as a DC path, which allows for a convenient method of locking the LTC6955 outputs to an external PLL/VCO.
LTM4647 High Efficiency, PolyPhase 120A Step-Down Power μModule Regulator
Analog Devices Inc.Demonstration circuit 2616A-D features a polyphase
design using the LTM4647EY, a 30A high efficiency,
switch mode step-down power µModule regulator. The
input voltage range is from 6V to 15V. To use DC2616A-D
for input voltage range from 4.7V to 6V, connect INTVCC
to SVIN (change R22, R42, R55, R68 from OPT to 0Ω),
DRVCC to VIN (change R21, R38, R52, R65 from 0Ω to
OPT, R2, R39, R53, R66 from OPT to 0Ω). The output voltage range is 0.6V to 1.8V. The DC2616A-D can deliver a
nominal 120A output current with four LTM4647 modules
in parallel. As explained in the data sheet, output current
derating is necessary for certain VIN, VOUT, and thermal
conditions. The board operates in continuous conduction mode in heavy load conditions. For high efficiency at low
load currents, the MODE_PLLIN jumper selects pulseskipping mode for noise sensitive applications or burst
mode operation in less noise sensitive applications. The
MODE_PLLIN pin also allows the LTM4647 to synchronize to an external clock signal. The phase shift between
two adjacent phases is 90 degrees. DC2616A-D has the
option of choosing both internal and external compensation circuit for LTM4647. The LTM4647 data sheet must
be read in conjunction with this demo manual prior to
working on or modifying demo circuit DC2616A-D.

Analog Devices Inc.The LTC6820 provides bidirectional SPI communications between two isolated devices through a single twisted-pair connection. Each LTC6820 encodes logic states into signals that are transmitted across an isolation barrier to another LTC6820. The receiving LTC6820 decodes the transmission and drives the slave bus to the appropriate logic states. The isolation barrier can be bridged by a simple pulse transformer to achieve hundreds of volts of isolation.The LTC6820 drives differential signals using matched source and sink currents, eliminating the requirement for a transformer center tap and reducing EMI. Precision window comparators in the receiver detect the differential signals. The drive currents and the comparator thresholds are set by a simple external resistor divider, allowing the system to be optimized for required cable lengths and desired signal-to-noise performance.Applications Industrial Networking Battery Monitoring Systems Remote Sensors
