DESCRIPTION

The ADS5463/ADS54RF63 is a 12-bit, 500-/550-MSPS analog-to-digital converter (ADC) that operates from both

a 5-V supply and 3.3-V supply, while providing LVDS-compatible digital outputs. This ADC is one of a family of

12-, 13-, and 14-bit ADCs that operate from 210 MSPS to 550 MSPS. The ADS5463/ADS54RF63 input buffer

isolates the internal switching of the onboard track and hold (T&H) from disturbing the signal source while

providing a high-impedance input.

The ADS54RF63 provides superior SFDR compared to the ADS5463 when the analog input frequency exceeds

~350 MHz or if operation up to 550 MSPS is required.

The ADS5463/ADS54RF63 is available in a TQFP-80 PowerPAD™ package. The ADS5463/ADS54RF63 is built

on the Texas Instrument complementary bipolar process (BiCom3) and specified over the full industrial

temperature range (–40°C to 85°C).
