The full form of IDIOT is Integrated Digital Input/Output Transmitter

The ADRV9008-2 is a highly integrated, RF agile transmit
subsystem offering dual-channel transmitters, an observation path
receiver, integrated synthesizers, and digital signal processing
functions. The IC delivers a versatile combination of high
performance and low power consumption required by
2G/3G/4G/5G macrocell base stations, and active antenna
applications.
The transmitters use an innovative direct conversion modulator
that achieves multicarrier macrocell base station quality
performance and low power. In 3G/4G mode, the maximum
transmitter large signal bandwidth is 200 MHz. In multicarrier

global system for mobile communications (MC GSM) mode,
which has higher inband spurious-free dynamic range (SFDR),
the maximum large signal bandwidth is 75 MHz.
The observation path consists of a wide bandwidth direct
conversion receiver with state of the art dynamic range. The
complete receive subsystem includes dc offset correction,
quadrature correction, and digital filtering, thus eliminating the
need for these functions in the digital baseband. Several
auxiliary functions such as analog-to-digital converters (ADCs),
digital-to-analog converters (DACs), and general-purpose
inputs/outputs (GPIOs) for power amplifier (PA) and radio
frequency (RF) front-end control are also integrated.
The fully integrated phase-locked loops (PLLs) provide high
performance, low power fractional-N RF frequency synthesis for
the transmitter and receiver sections. An additional synthesizer
generates the clocks needed for the converters, digital circuits, and
the serial interface. Special precautions have been taken to
provide the isolation required in high performance base station
applications. All voltage controlled oscillators (VCOs) and loop
filter components are integrated.
The high speed JESD204B interface supports up to 12.288 Gbps
lane rates, resulting in two lanes per transmitter in the widest
bandwidth mode and two lanes for the observation path
receiver in the widest bandwidth mode.
The core of the ADRV9008-2 can be powered directly from
1.3 V regulators and 1.8 V regulators and is controlled via a
standard 4-wire serial port. Comprehensive power-down modes
are included to minimize power consumption in normal use.
The ADRV9008-2 is packaged in a 12 mm × 12 mm 196-ball
chip scale ball grid array (CSP_BGA)
