1.8V, 12-Bit, 170Msps ADC for
Broadband Applications
General Description
Features
The MAX1213 is a monolithic, 12-bit, 170Msps analog-
to-digital converter (ADC) optimized for outstanding
dynamic performance at high-IF frequencies up to
300MHz. The product operates with conversion rates
up to 170Msps while consuming only 788mW.
ꢀ 170Msps Conversion Rate
ꢀ Low Noise Floor of -68dBFS
ꢀ Excellent Low-Noise Characteristics
SNR = 65.8dB at f = 65MHz
IN
SNR = 64.5dB at f = 250MHz
IN
At 170Msps and an input frequency up to 250MHz, the
MAX1213 achieves a spurious-free dynamic range
(SFDR) of 72.9dBc. Its excellent signal-to-noise ratio
(SNR) of 65.8dB at 10MHz remains flat (within 2dB) for
input tones up to 250MHz. This ADC yields an excellent
low-noise floor of -68dBFS, which makes it ideal for
wideband applications such as cable head-end
receivers and power-amplifier predistortion in cellular
base-station transceivers.

SAMPLE
The MAX1213 requires a single 1.8V supply. The analog
input is designed for either differential or single-ended
operation and can be AC- or DC-coupled. The ADC also
features a selectable on-chip divide-by-2 clock circuit,
which allows the user to apply clock frequencies as high
as 340MHz. This helps to reduce the phase noise of the
input clock source. A low-voltage differential signal
(LVDS) sampling clock is recommended for best perfor-
mance. The converter’s digital outputs are LVDS com-
patible and the data format can be selected to be either
two’s complement or offset binary.
