heet4U 1.8V, 1B2r-oBaidt,b1a7n0dMAspppsliAcaDtCiofnosrGeneral Description
SThe MAX1213 is a monolithic, 12-bit, 170Msps analog-
tato-digital converter (ADC) optimized for outstanding
adynamic performance at high-IF frequencies up to
.D300MHz. The product operates with conversion rates
up to 170Msps while consuming only 788mW.
wAt 170Msps and an input frequency up to 250MHz, the
wMAX1213 achieves a spurious-free dynamic range
w(SFDR) of 72.9dBc. Its excellent signal-to-noise ratio
(SNR) of 65.8dB at 10MHz remains flat (within 2dB) for
minput tones up to 250MHz. This ADC yields an excellent
olow-noise floor of -68dBFS, which makes it ideal for
wideband applications such as cable head-end
.creceivers and power-amplifier predistortion in cellular
base-station transceivers.
The MAX1213 requires a single 1.8V supply. The analog
Uinput is designed for either differential or single-ended
operation and can be AC- or DC-coupled. The ADC also
t4features 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
einput clock source. A low-voltage differential signal
e(LVDS) sampling clock is recommended for best perfor-
mance. The converter’s digital outputs are LVDS com-
hpatible and the data format can be selected to be either
two’s complement or offset binary.
SThe MAX1213 is available in a 68-pin QFN package
with exposed paddle (EP) and is specified over the
taindustrial (-40°C to +85°C) temperature range.
See the Pin-Compatible Versions table for a complete
aselection of 8-bit, 10-bit, and 12-bit high-speed ADCs in
this family.
