Performance Summary - Linear Technology DC2183A Demo Manual

Description
Demonstration circuit 2183A supports the
high speed and high dynamic range ADC. It was specially
designed for applications that require a single-ended AC-
coupled input. DC2183 supports the LTC2107 using the
DDR LVDS output mode.
The LTC2107 characteristics are listed in Table 1. De-
pending on the version, the circuitry on the analog inputs
is optimized for analog input frequencies from 5MHz to
70MHz or 70MHz to 180MHz.
