DC1954A-C

DC1954A-C demonstration circuit features LTC6954IUFF-3 a low phase noise, triple output clock distribution divider/driver. The DC1954A LVPECL outputs are AC-coupled 50 ohm transmission lines making them suitable for driving 50 ohm impedance instruments. The LVDS/CMOS outputs of the DC1954A are terminated with a 100 ohm differential resistor and are DC-coupled. All differential input and outputs have 0.5" spaced SMA connectors. The LTC6954’s EZSync™ function is made available via a turret and an SMA connector. A DC590 USB serial controller board is used for SPI communication with the LTC6954, controlled by the supplied LTC6954-GUI software.

• LVPECL OUT0+/-, LVDS/CMOS OUT1+/- and LVDS/CMOS OUT2+/-
• DC1954A-C: low noise clock distribution suitable for high speed/high resolution ADC clocking
