Dual-Channel, 250-MSPS Feedback Receiver IC
Checkfor Samples: ADS62PF49
1FEATURES DESCRIPTIONThe ADS62PF49isa dual-channel feedback reciever•
Maximum Output Sample Rate: 250 MSPS IC with sampling rates upto 250 MSPS.It allowsa•
Pin-Compatible with ADS62P49 high-resolution, 14-bit output for a limited time•
Variable Output Resolution followedbya low-resolution mode witha minimumof–
High Resolution Burst Mode with 14-Bit 8x longer time.Itis pin-compatibleto the ADS62P49
Output:73 dB SNRat Low IF, and ADS62C17 dual ADCs.
70.5 dB SNRat 170 MHz The ADS62PF49 has gain options that can be used–
Low Resolution with 9-Bit 250 MSPSor to improve SFDR performance at lower full-scale
11-Bit 125 MSPS input ranges.It includesa dc offset correction loop•
Double Data Rate (DDR) LVDS Output that can be used to cancel the analog-to-digital
conversion (ADC) offset.•
Programmable Gain upto6 dB for SNR/SFDR
Trade-off It includes internal references while the traditional•
90-dB Cross-Talk reference pins and associated decoupling capacitors
Power Consumptionof 1.25W have been eliminated. The deviceis specified over
the industrial temperature range (–40°Cto 85°C).•
