1. General description
The ADC1413D is a dual channel 14-bit Analog-to-Digital Converter (ADC) optimized for
high dynamic performances and low power at sample rates up to 125 Msps. Pipelined
architecture and output error correction ensure the ADC1413D is accurate enough to
guarantee zero missing codes over the entire operating range. Supplied from a 3.3 V
source for analog and a 1.8 V source for the output driver, it has two serial outputs,
because of the two lanes of differential outputs, which are compliant with the JESD204A
standard. An integrated SPI (Serial Peripheral Interface) allows the user to easily
configure the ADC. A set of IC configurations is also available via the binary level control
pins taken, which are used at power-up. The device also includes a programmable gain
amplifier with flexible input voltage range.
Excellent dynamic performance is maintained from the baseband to input frequencies of
170 MHz or more, making the ADC1413D ideal for use in communications, imaging and
medical applications.

13. Application information
13.1 Analog inputs
13.1.1 Input stage description
The ADC1413D inputs can be configured as single-ended or differential (selected via SPI
control bit DIFF/SE; see Table 20). Optimal performance is achieved using differential
inputs with the common-mode input voltage, VI(cm), set to VDDA/2.
The full scale analog input voltage range is configurable between ± 1 V (p-p) and
± 2 V (p-p) via a programmable internal reference (see Section 13.2 and Table 21 for
further details).
The equivalent circuit of the sample and hold input stage, including ESD protection and
circuit and package parasitics, is shown in Figure 5.

Input sampling circuit
The sample phase HIGH, because of the NMOS transistors. The voltage is then held on
the sampling capacitors. When the clock signal goes LOW, the stage enters the hold
phase and the voltage information is transmitted to the ADC core.
13.1.2 Anti-kickback circuitry
Anti-kickback circuitry is needed to counteract the effects of charge injection generated by
the sampling capacitance. This consists of an RC filter containing a resistor in series
(typically 12 Ω to 25 Ω) and a capacitor in parallel (typically 8 pF to 12 pF).
The RC filter is also used to filter noise from the signal before it reaches the sampling
stage. The value of the capacitor should be chosen to maximize noise attenuation without
degrading the settling time too much.
The RC coupling is determined by the input frequency and should be selected so as not to
affect the input bandwidth.

The configuration shown in Figure 7 is recommended for high frequency applications. In
both cases, the choice of transformer will be a compromise between cost and
performance.
13.2 System reference and power management
13.2.1 Internal/external reference
The ADC1413D has a stable and accurate built-in internal reference voltage. This
reference voltage can be set internally, externally or programmed, in 1 dB steps between
0 dB and −6 dB, via SPI control bits INTREF (when bit INTREF_EN = 1; see Table 21).
The equivalent reference circuit is shown in Figure 8.

13.2.2 Gain control
The gain is programmable between 0 dB to −6 dB in steps of 1 dB via the SPI
(see Table 21). This makes it possible to improve the Spurious-Free Dynamic Range
(SFDR) of the ADC1413D. The corresponding full scale input voltage range varies
between 2 V (p-p) and 1 V (p-p), as shown in Table 11:

13.2.3 Common-mode output voltage (VI(cm))
An 0.1 µF filter capacitor should be connected between on the one hand the pins VCMA
and VCMB and on the other hand ground to ensure a low-noise common-mode output
voltage. When AC-coupled, these pins can be used to set the common-mode reference
for the analog inputs, for instance via a transformer middle point.

The common-mode output voltage, VO(cm), should be set externally to 1.5 V (typical).The
common-mode input voltage, VI(cm), at the inputs to the sample and hold stage
(pins INAM, INBM, INAP, and INBP) must be between 0.9 V and 2 V for optimal
performance. Figure 14 illustrates how the SFDR and SNR characteristics vary with
changes in the common-mode input voltage.

13.3.1 Drive modes
The ADC1413D can be driven differentially (SINE, LVPECL or LVDS) without the
performance being affected by the choice of configuration. It can also be driven by a
single-ended LVCMOS signal connected to pin CLKP (CLKM should be connected to
ground via a capacitor).

Single-ended or differential clock inputs can be selected via the SPI interface
(see Table 20). If single-ended is selected, the input pin (CLKM or CLKP) is selected via
control bit SE_SEL.
If single-ended is implemented without setting SE_SEL accordingly, the unused pin
should be connected to ground via a capacitor.
13.3.3 Duty cycle stabilizer
The duty cycle stabilizer can improve the overall performances of the ADC by
compensating the input clock signal duty cycle. When the duty cycle stabilizer is active
(bit DCS_EN = 1; see Table 20), the circuit can handle signals with duty cycles of between
30 % and 70 % (typical). When the duty cycle stabilizer is disabled (DCS_EN = 0), the
input clock signal should have a duty cycle of between 45 % and 55 %.

The block placed after the ADC cores is used to implement all functionalities of the
JESD204A standard. This ensures signal integrity and guarantees the clock and the data
recovery at the receiver side.
The block is highly parameterized and can be configured in various ways depending on
the sampling frequency and the number of lanes used.

13.6 Serial Peripheral Interface (SPI)
13.6.1 Register description
The ADC1413D serial interface is a synchronous serial communications port allowing for
easy interfacing with many industry microprocessors. It provides access to the registers
that control the operation of the chip in both read and write modes.
This interface is configured as a 3-wire type (SDIO as bidirectional pin).
SCLK acts as the serial clock, and CSB acts as the serial chip select bar.
Each read/write operation is sequenced by the CSB signal and enabled by a LOW level to
to drive the chip with 2 bytes to 5 bytes, depending on the content of the instruction byte
(see Table 14).

Bits A12 to A0 indicate the address of the register being accessed. In the case of a
multiple byte transfer, this address is the first register to be accessed. An address counter
is incremented to access subsequent addresses.
The steps involved in a data transfer are as follows:
1. The falling edge on CSB in combination with a rising edge on SCLK determine the
start of communications.
2. The first phase is the transfer of the 2-byte instruction.
3. The second phase is the transfer of the data which can be vary in length but will
always be a multiple of 8 bits. The MSB is always sent first (for instruction and data
bytes):

13.6.2 Channel control
The two ADC channels can be configured at the same time or separately. By using the
register “Channel index”, the user can choose which ADC channel will receive the next
SPI-instruction. By default the channel A and B will receive the same instructions.
