ADC1415S

ADC1415S series Single 14-bit ADC; 65 Msps, 80 Msps, 105 Msps or 125 Msps with input buffer; CMOS or LVDS DDR digital outputs Rev. 4 — 17 December 2010 Product data sheet 1. General description The ADC1415S is a single channel 14-bit Analog-to-Digital Converter (ADC) optimized for high dynamic performance and low power consumption at sample rates up to 125 Msps. Pipelined architecture and output error correction ensure the ADC1415S is accurate enough to guarantee zero missing codes over the entire operating range. Supplied from a single 3 V source, it can handle output logic levels from 1.8 V to 3.3 V in CMOS mode, thanks to a separate digital output supply. The ADC1415S supports the Low Voltage Differential Signalling (LVDS) Double Data Rate (DDR) output standard. An integrated Serial Peripheral Interface (SPI) allows the user to easily configure the ADC. The device also includes a SPI programmable full-scale to allow flexible input voltage range from 1 V to 2 V (peak-to-peak). With excellent dynamic performance from the baseband to input frequencies of 170 MHz or more, the ADC1415S is ideal for use in communications, imaging and medical applications - especially in high Intermediate Frequency (IF) applications thanks to the integrated input buffer. The input buffer ensures that the input impedance remains constant and low and the performance consistent over a wide frequency range. 2.

Application information 11.1 Device control The ADC1415S can be controlled via the Serial Peripheral Interface (SPI control mode) or directly via the I/O pins (Pin control mode). 11.1.1 SPI and Pin control modes The device enters Pin control mode at power-up, and remains in this mode as long as pin CS is held HIGH. In Pin control mode, the SPI pins SDIO, CS and SCLK are used as static control pins. SPI control mode is enabled by forcing pin CS LOW. Once SPI control mode has been enabled, the device remains in this mode. The transition from Pin control mode to SPI control mode is illustrated in Figure 13.

LVDS DDR is selected when ODS is HIGH, otherwise CMOS is selected. 11.1.4 Selecting the output data format The output data format can be selected via the SPI interface (offset binary, two’s complement or gray code; see Table 23) or using pin DFS in Pin control mode (offset binary or two’s complement). Offset binary is selected when DFS is LOW. When DFS is HIGH, two’s complement is selected. 11.2 Analog inputs 11.2.1 Input stage The analog input of the ADC1415S supports a differential or a single-ended input drive. Optimal performance is achieved using differential inputs. The ADC inputs are internally biased and need to be decoupled. 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 11.3 and Table 21). The equivalent circuit of the input buffer followed by the Sample and Hold (S/H) input stage, including ElectroStatic Discharge (ESD) protection and circuit and package parasitics, is shown in Figure 14.

Input sampling circuit and input buffer The integrated input buffer offers the following advantages: • The kickback effect is avoided - the charge injection and glitches generated by the S/H input stage are isolated from the input circuitry. So there’s no need for additional filtering. • The input capacitance is very low and constant over a wide frequency range, which makes the ADC1415S easy to drive. The sample phase occurs when the internal clock (derived from the clock signal on pin CLKP/CLKM) is HIGH. 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.

If single-ended is enabled, the input pin (CLKM or CLKP) is selected via control bit SE_SEL. If single-ended is implemented without setting bit SE_SEL to the appropriate value, the unused pin should be connected to ground via a capacitor. 11.4.3 Duty cycle stabilizer The duty cycle stabilizer can improve the overall performance of the ADC by compensating the duty cycle of the input clock signal. When the duty cycle stabilizer is active (bit DCS_EN = logic 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 = logic 0), the input clock signal should have a duty cycle of between 45 % and 55 %. 11.4.4 Clock input divider The ADC1415S contains an input clock divider that divides the incoming clock by a factor of 2 (when bit CLKDIV = logic 1; see Table 20). This feature allows the user to deliver a higher clock frequency with better jitter performance, leading to a better SNR result once acquisition has been performed.

It provides access to the registers that control the operation of the chip. This interface is configured as a 3-wire type (SDIO as bidirectional pin) Pin SCLK is the serial clock input and CS is the chip select pin. Each read/write operation is initiated by a LOW level on CS. A minimum of three bytes is transmitted (two instruction bytes and at least one data byte). The number of data bytes is determined by the value of bits W1 and W2 (see Table 17). Table 16.

An address counter is increased to access subsequent addresses. The steps involved in a data transfer are as follows: 1. A falling edge on CS 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 vary in length but is always a multiple of 8 bits. The MSB is always sent first (for instruction and data bytes). 4.

SPI mode timing 11.6.2 Default modes at start-up During circuit initialization it does not matter which output data standard has been selected. At power-up, the device enters Pin control mode. A falling edge on CS triggers a transition to SPI control mode. When the ADC1415S enters SPI control mode, the output data standard (CMOS/LVDS DDR) is determined by the level on pin SDIO (see Figure 29). Once in SPI control mode, the output data standard can be changed via bit LVDS/CMOS in Table 23. When the ADC1415S enters SPI control mode, the output data format (two’s complement or offset binary) is determined by the level on pin SCLK (gray code can only be selected via the SPI). Once in SPI control mode, the output data format can be changed via bit DATA_FORMAT[1:0] in Table 23.
