Linear Technology DC1565A Demo Manual

Description
Demonstration circuit 1565A supports a family of
12‑Bit/14‑Bit 170Msps to 310Msps ADCs. Each assem‑
bly features one of the following devices: LTC2153‑14/
LTC2153‑12, LTC2152‑14/LTC2152‑12, LTC2151‑14/
LTC2151‑12, LTC2150‑14/LTC2150‑12, high speed ADCs.
The versions of the 1565A demo board are listed in Table 1.
Depending on the required resolution and sample rate,
the DC1565A is supplied with the appropriate ADC. The
