The KAD2710L is the industry’s lowest power, 10-bit,
275MSPS, high performance Analog-to-Digital converter. It
is designed with Intersil’s proprietary FemtoCharge™
technology on a standard CMOS process. The KAD2710L
offers high dynamic performance (55.6dBFS SNR @
f
include an over-range indicator and a selectable divide-by-2
input clock divider. The KAD2710L is one member of a
pin-compatible family offering 8 and 10-bit ADCs with
sample rates from 105MSPS to 350MSPS and
LVDS-compatible or LVCMOS outputs (Table 1). This family
of products is available in 68-pin RoHS-compliant QFN
packages with exposed paddle. Performance is specified
over the full industrial temperature range (-40°c to +85°C).

... KAD2710L Ω VCM 25O Use of the clock divider is optional. The KAD2710L's ADC 0.1µF requires a clock with 50% duty cycle for optimum performance. If such a clock is not available, one option is to generate twice the desired sampling rate and use the KAD2710L's divide-by-2 setting. This frequency divider uses the rising edge of the clock, so 50% clock duty cycle is assured ...
