December 10, 2012 14-Bit, 500MSPS ADC
The ISLA214P50 is a 14-bit, 500MSPS analog-to-digital converter
designed with Intersil’s proprietary FemtoCharge™ technology on
a standard CMOS process. The ISLA214P50 is part of a
pin-compatible portfolio of 12 to 16-bit A/Ds with maximum
sample rates ranging from 130MSPS to 500MSPS.
The device utilizes two time-interleaved 250MSPS unit ADCs to
achieve the ultimate sample rate of 500MSPS. A single 500MHz
conversion clock is presented to the converter, and all interleave
clocking is managed internally. The proprietary Intersil Interleave
Engine (I2E) performs automatic correction of offset, gain, and
sample time mismatches between the unit ADCs to optimize
performance.
A serial peripheral interface (SPI) port allows for extensive
configurability of the A/D. The SPI also controls the interleave
correction circuitry, allowing the system to issue offline and
continuous calibration commands as well as configure many
dynamic parameters.
Digital output data is presented in selectable LVDS or CMOS
formats. The ISLA214P50 is available in a 72 Ld QFN package …

August 1, 2011 12-Bit, 500MSPS A/D Converter
The ISLA112P50 is a low-power, high-performance, 500MSPS
analog-to-digital converter designed with Intersil’s proprietary
FemtoChargeв„ў technology on a standard CMOS process. The
ISLA112P50 is part of a pin-compatible portfolio of 8, 10 and
12-bit A/Ds. This device an upgrade of the KAD551XP-50
product family and is pin similar.
The device utilizes two time-interleaved 250MSPS unit A/Ds to
achieve the ultimate sample rate of 500MSPS. A single
500MHz conversion clock is presented to the converter, and all
interleave clocking is managed internally. The proprietary
Intersil Interleave Engine (I2E) performs automatic fine
correction of offset, gain, and sample time skew mismatches
between the unit A/Ds to optimize performance. No external
interleaving algorithm is required.
A serial peripheral interface (SPI) port allows for extensive
configurability of the A/D. The SPI also controls the interleave
correction circuitry, allowing the system to issue continuous
calibration commands as well as configure many dynamic
parameters. CLKP Multiple Chip Time Alignment Support via the Synchronous …

Wideband, Low Noise, Low Distortion, Fixed Gain,
Differential Amplifier
ISL55211 Features The ISL55211 is a wideband, differential input to differential
output amplifier offering 3 possible internal gain settings.
Using fixed 500Ω internal feedback resistors, the amplifier
may be configured for a differential gain of 2, 4 or 5V/V
depending on which combination of input pins are connected
to the signal source. Internal feedback capacitors controls the
signal bandwidth to be a constant 1.4GHz in all gain settings. 3 Fixed Gain Options . 2, 4, or 5V/V Constant Bandwidth Over Gain 1.4GHz Differential Slew Rate . 5,600V/µs 2VP-P, 2-tone IM3 (200Ω) 100MHz -103dBc Low Differential Output Noise (Gain 5V/V) <12nV/√Hz Supply Voltage Range 3.0V to 4.2V Ideally suited for AC-coupled data acquisition applications, the
output DC common mode voltage is controlled through an
external VCM pin or left to default to 1.2V above the negative
supply pin. Where the differential signal source is AC-coupled,
the input common mode voltage will equal the output
common mode voltage. Quiescent Power (3.3V Supply) . .115mW Applications Low Power, High Dynamic Range ADC Interface Differential Mixer Output Amplifier Intended for very high dynamic range ADC interface
applications, the ISL55211 offers 5600V/Вµs differential slew
rate, <12nV/в€љHz output noise, and >100dBc SFDR to
>100MHz for 2VP-P 2-tone 3rd order intermodulation. Its
balanced architecture effectively suppresses even order
distortion terms -an important issue for very wide band 1st
Nyquist zone ADC interface applications. Minimum gain
operation of 2V/V (6dB) with <1dB peaking ensures stable
performance over-temperature. It's ultra high differential slew
rate of 5600V/Вµs provides adequate performance margin for …

Jun 6, 2013 Wideband, Low-Power, Ultra-High Dynamic Range Differential Amplifier
The ISL55210 is a very wide band, Fully Differential Amplifier
(FDA) intended for high dynamic range ADC input interface
applications. This voltage feedback FDA design includes an
independent output common mode voltage control. Features Intended for very high dynamic range ADC interface
applications, at the lowest quiescent power (115mW), the
ISL55210 offers a 4.0GHz Gain Bandwidth Product with a very
low input noise of 0.85nV/в€љ(Hz). In a balanced differential I/O
configuration, with 2VP-P output into a 200О© load configured
for a gain of 15dB, the IM3 terms are <-100dBc through
110MHz. With a minimum operating gain of 2V/V (6dB), the
ISL55210 supports a wide range of higher gains with minimal
BW or SFDR degradation. Its ultra high differential slew rate of
5,600V/Вµs ensures clean large signal SFDR performance or a
fast settling step response. Differential Slew Rate . 5,600V/Вµs The ISL55210 requires only a single 3.3V (max 4.2V) power
supply with 35mA typical quiescent current. This industry
leading low current solution can be further reduced when
needed using the optional power shutdown to <0.4mA supply
current. External feedback and gain setting resistors give
maximum flexibility and accuracy. A companion device, the …
