Inphi 1821TH
The 1821TH track-and-hold amplifier is designed for high-precision sampling of wideband signals with multi-GHz frequency content. The masterslave architecture integrates two track-and-hold circuits, a 50-ohm differential output buffer, and clock mode selection logic. The output is settled for nearly a complete clock cycle of the slave T/H.APPLICATIONS

DESCRIPTION
Sample rates up to 2 GS/s are supported. Clock modes include out-of-phase master-slave (M/S) clocking based on a single clock signal and independent M/S clocking based on two clock signals. Analog inputs are direct coupled and terminated on-chip with 50 ohms to a user-adjustable voltage.● Digital receiver systems
