The MAX101 is an ECL-compatible ADC with a sampling rate of 500Msps and 8-bit resolution. It accurately digitizes analog signals from DC to 250MHz (Nyquist frequency). The MAX101 is designed using Maxim's proprietary advanced bipolar processes and features a high-performance T/H amplifier and two quantizers. The innovative design of the internal T/H ensures an exceptionally wide 1.2GHz input bandwidth and aperture delay uncertainty of less than 2ps, resulting in a high 7.0 effective bits at the Nyquist frequency. Special comparator output design and decoding circuitry reduce out-of-sequence code errors. The probability of erroneous codes due to metastable states is reduced to less than 1 error per 10^15 clock cycles. Unlike other ADCs that can have errors resulting in false full-scale or zero-scale outputs, the MAX101 keeps the error magnitude to less than 1LSB. The analog input is designed for either differential or single-ended use with a ±270mV range. Sense pins for the reference input allow full-scale calibration of the input range or facilitate ratiometric use. Phase adjustment is available to optimize the relative sampling of the converter halves. Input clock phasing is also available for interleaving several MAX101s for higher effective sampling rates.

The MAX100 evaluation kit (EV kit) allows high-speed digitizing of analog signals at 250Msps, using the MAX100 ADC. All circuitry required to support the ADC is supplied. Data output is available in three formats: divide-by-1, divide-by-2, or divide-by-5 mode. Clocking is provided by an external clock source input through an SMA connector. The MAX100 EV kit main board comes complete with a MAX100 high-speed, 8-bit flash ADC with strobed comparators, latched outputs, and an internal track/hold. Analog input to the board is through two SMA coaxial connectors, for use with either differential or single-ended inputs. Signals from the main board include dual-output data paths that allow easy interfacing to external circuitry. These two outputs can be configured either to provide two identical fast outputs (A and B), or an 8-to-16 demultiplexer mode that reduces the output data rates to one-half the sample clock rate. This demux is internal to the MAX100 ADC and is one of the key features of this device. A termination board with 50Ω ECL pull-down resistors is also supplied, and is connected to the main board with a 3x32 pin EURO-card connector. It provides access to the converter output data and provides proper ECL data termination. In addition to the pull-down resistors, this board has two ranks of square pins, each providing eight differential data outputs plus clock outputs. Either AData or BData may be observed with a high-speed logic

The MAX1002 is a dual, 6-bit analog-to-digital converter (ADC) that combines high-speed, low-power operation with a user-selectable input range, an internal reference, and a clock oscillator. The dual, parallel ADCs are designed to convert in-phase (I) and quadrature (Q) analog signals into two 6-bit offset-binary-coded digital outputs at sampling rates up to 60Msps while achieving typical integral nonlinearity (INL) and differential nonlinearity (DNL) of ±1/4LSB. The ability to interface directly with baseband I and Q signals makes the MAX1002 ideal for use in direct-broadcast satellite, VSAT, and QAM16 demodulation applications. The MAX1002 input amplifiers feature true differential inputs, a 55MHz -0.5dB analog bandwidth, and user-programmable input full-scale ranges of 125mVp-p, 250mVp-p, or 500mVp-p. With an AC-coupled input signal, matching performance between input channels is typically 0.1dB gain, 1/4LSB offset, and 0.5° phase. Dynamic performance is 5.85 effective number of bits (ENOB) with a 20MHz analog input signal, or 5.78 ENOB with a 50MHz input signal. The MAX1002 operates with a single +5V power supply and provides TTL-compatible digital outputs. The device is available in the commercial temperature range (0°C to +70°C) and comes in a 36-pin SSOP package.

The MAX038 is a high-frequency, precision function generator producing accurate, high-frequency triangle, sawtooth, sine, square, and pulse waveforms with a minimum of external components. The output frequency can be controlled over a frequency range of 0.1Hz to 20MHz by an internal 2.5V bandgap voltage reference and an external resistor and capacitor. The duty cycle can be varied over a wide range by applying a ±2.3V control signal, facilitating pulse-width modulation and the generation of sawtooth waveforms. Frequency modulation and frequency sweeping are achieved in the same way. The duty cycle and frequency controls are independent. Sine, square, or triangle waveforms can be selected at the output by setting the appropriate code at two TTL-compatible select pins. The output signal for all waveforms is a 2VP-P signal that is symmetrical around ground. The low-impedance output can drive up to ±20mA. The TTL-compatible SYNC output from the internal oscillator maintains a 50% duty cycle—regardless of the duty cycle of the other waveforms—to synchronize other devices in the system. The internal oscillator can be synchronized to an external TTL clock connected to PDI.

The DS4303 is a nonvolatile (NV) sample and infinite-hold adjustable voltage reference. The reference voltage is programmed in-circuit during factory calibration/ programming. Programming the reference voltage, VOUT, is as simple as applying the desired voltage on VIN and toggling the adjust pin (ADJ) to lock the VOUT voltage level indefinitely, even if the device is power cycled. The DS4303 replaces current cumbersome factory adjustment arrangements with a low-cost solution that can be adjusted using automated techniques. In addition, the DS4303 has the ability to be readjusted after the unit has been fully assembled and tested. This results in a much more flexible manufacturing arrangement, lower inventory costs, and a quicker time-to-market.
