ADC1006S055/070 Single 10 bits ADC, up to 55 MHz or 70 MHz Rev. 03 — 2 July 2012 Product data sheet 1. General description The ADC1006S055/070 are a family of Bipolar CMOS (BiCMOS) 10-bit Analog-to-Digital Converters (ADC) optimized for a wide range of applications such as cellular infrastructures, professional telecommunications, imaging, and digital radio. It converts the analog input signal into 10-bit binary coded digital words at a maximum sampling rate of 70 MHz. All static digital inputs (SH, CE and OTC) are Transistor-Transistor Logic (TTL) and CMOS compatible and all outputs are CMOS compatible. A sine wave clock input signal can also be used. 2.

The circuit has two clock inputs: CLK and CLKN. There are 5 modes of operation: a) PECL mode 1: (DC level vary 1 : 1 with VCCD) CLK and CLKN inputs are at differential PECL levels. b) PECL mode 2: (DC level vary 1 : 1 with VCCD) CLK input is at PECL level and sampling is taken on the falling edge of the clock input signal. A DC level of 3.65 V has to be applied on CLKN decoupled to GND via a 100 nF capacitor. c) PECL mode 3: (DC level vary 1 : 1 with VCCD) CLKN input is at PECL level and sampling is taken on the rising edge of the clock input signal. A DC level of 3.65 V has to be applied on CLK decoupled to GND via a 100 nF capacitor. d) Differential AC driving mode 4: When driving the CLK input directly and with any AC signal of minimum 1 V (p-p) and with a DC level of 2.5 V, the sampling takes place at the falling edge of the clock signal. When driving the CLKN input with the same signal, sampling takes place at the rising edge of the clock signal. It is recommended to decouple the CLKN or CLK input to DGND via a 100 nF capacitor. e) TTL mode 1: CLK input is at TTL level and sampling is taken on the falling edge of the clock input signal. In that case CLKN pin has to be connected to the ground. [3] The ADC input range can be adjusted with an external reference connected to VREF pin. This voltage has to be referenced to VCCA; see Figure 12. [4] The 3 dB analog bandwidth is determined by the 3 dB reduction in the reconstructed output, the input being a full-scale sine wave. [5] Total Harmonic Distortion (THD) is obtained with the addition of the first five harmonics: 2 2 2 2 2 2H + 3H + 4H + + 6H THD = 20 log -------------------------------------------------------------------------------------------------------------------------------------2 a 1H where 1H is the fundamental harmonic referenced at 0 dB for a full-scale sine wave input; see Figure 6. [6] Signal-to-noise ratio (S/N) takes into account all harmonics above five and noise up to Nyquist frequency; see Figure 8. [7] Effective number of bits are obtained via a Fast Fourier Transform (FFT). The calculation takes into account all harmonics and noise up to half of the clock frequency (Nyquist frequency). Conversion to SIgnal-to_Noise_Distortion ratio (SINAD) is given by SINAD = ENOB 6.02 + 1.76 dB; see Figure 5. [8] Intermodulation measured relative to either tone with analog input frequencies of 20 MHz and 20.1 MHz. The two input signals have the same amplitude and the total amplitude of both signals provides full-scale to the converter (6 dB below full scale for each input signal). IMD3 is the ratio of the RMS value of either input tone to the RMS value of the worst case third order intermodulation product. [9] Output data acquisition: the output data is available after the maximum delay of td(o); see Figure 3. ADC1006S055_070_3 Product data sheet © IDT 2012. All rights reserved.

Support information 13.1 Definitions 13.1.1 Non-linearities 13.1.1.1 Integral Non-Linearity (INL) It is defined as the deviation of the transfer function from a best fit straight line (linear regression computation). The INL of the code i is obtained from the equation: V I i – V I ideal INL i = -----------------------------------------S (1) n where i = 0 2 – 1 and S = slope of the ideal straight line = code width; i = code value. 13.1.1.2 Differential Non-Linearity (DNL) It is the deviation in code width from the value of 1 LSB.

A good approximation gives: ENOB = SINAD dB – 1.76 6.02 13.1.2.3 Total Harmonic Distortion (THD) The ratio of the power of the harmonics to the power of the fundamental. For k-1 harmonics the THD is: P harmonics THD dB = 10 log --------------------------P signal 2 2 (4) 2 2 where P harmonics = 2 + 3 + k and P signal = 1 The value of k is usually 6 (i.e. calculation of THD is done on the first 5 harmonics). 13.1.2.4 Signal-to-Noise ratio (S/N) The ratio of the output signal power to the noise power, excluding the harmonics and the DC component. P signal S/N dB = 10 log ----------------P noise 13.1.2.5 (5) Spurious Free Dynamic Range (SFDR) The number SFDR specifies available signal range as the spectral distance between the amplitude of the fundamental and the amplitude of the largest spurious (harmonic and non-harmonic), excluding DC component. 1 SFDR dB = 20 log ----------------max s ADC1006S055_070_3 Product data sheet (6) © IDT 2012.

Spectral analysis (dual-tone) From a dual-tone input sinusoid (ft1 and ft2, these frequencies being chosen according to the coherence criterion), the intermodulation distortion products IMD2 and IMD3 (respectively, 2nd and 3rd-order components) are defined, as follows. 13.1.3.2 IMD2 (IMD3) The ratio of the RMS value of either tone to the RMS value of the worst second (third) order intermodulation product. The total IMD is given by: P intermod IMD dB = 10 log ----------------------P signal where, P intermod = a +a 2 2f t1 im 2 2 f im t1 – f t2 + a – f t2 – a 2 2f t1 im 2 f im t1 + f t2 + a 2 f im t1 – 2f t2 + a 2 f im t1 + 2f t2 + f t2 2 P signal = a f t1 + a f t2 and 2 a im f t is the power in the intermodulation component at frequency ft. 13.1.4 Noise Power Ratio (NPR) When using a notch-filtered broadband white-noise generator as the input to the ADC under test, the NPR is defined as the ratio of the average out-of-notch to the in-notch power spectral density magnitudes for the FFT spectrum of the ADC output sample set.
