The LTC6954 is a family of very low phase noise clock distribution parts. Each part has three outputs and each output has an individually programmable frequency divider and delay. There are four members of the family, differing in their output logic signal type:LTC6954-1: Three LVPECL outputsLTC6954-2: Two LVPECL and one LVDS/CMOS outputsLTC6954-3: One LVPECL and two LVDS/CMOS outputsLTC6954-4: Three LVDS/CMOS outputsEach output is individually programmable to divide the input frequency by any integer from 1 to 63, and to delay each output by 0 to 63 input clock cycles. The output duty cycle is always 50%, regardless of the divide number. The LVDS/CMOS outputs are jumper selectable via the OUTxSEL pins to provide either an LVDS logic output or a CMOS logic output.The LTC6954 also features Linear Technology?s EZSync system for perfect clock synchronization and alignment every time.All device settings are controlled through an SPI-compatible serial port.Applications Clocking High Speed, High Resolution ADCs, DACs?and Data Acquisition Systems Low Jitter Clock Distribution

Demonstration circuit 2041A is a regulated output voltage switched-capacitor step-down power supply featuring the 50mA output LTC3255. When VIN exceeds VOUT by more the 2:1, a 2:1 step-down architecture is used to efficiently regulate the output voltage, reducing the input current needed. As VIN reduces below twice VOUT, the LTC3255 will automatically switch to 1:1 mode. The demo board has a 4V to 48V input votlage range and a jumper-selectable output voltage than can be set to 2.5V, 3.3V, 5V, 12V or a user-defined value. The LTC3255 also has an integrated shunt regulator allowing it to provide a regulated output from a 4mA to 20mA current loop. The LTC3255 is a robust device that can survive -52V/60V reverse polarity input supplies, and features short-circuit protection and overtemperature protection.
