MAX106

The MAX106 PECL-compatible, 600Msps, 8-bit analog-todigital converter (ADC) allows accurate digitizing of analog signals with bandwidths to 2.2GHz. Fabricated on Maxim's proprietary advanced GST-2 bipolar process, the MAX106 integrates a high-performance track/hold (T/H) amplifier and a quantizer on a single monolithic die.

The innovative design of the internal T/H, which has an exceptionally wide 2.2GHz full-power input bandwidth, results in high, 7.6 effective bits performance at the Nyquist frequency. A fully differential comparator design and decoding circuitry combine to reduce out-ofsequence code errors (thermometer bubbles or sparkle codes) and provide excellent metastable performance of one error per 10²⁷ clock cycles. Unlike other ADCs, which can have errors that result in false full- or zero-scale outputs, the MAX106 limits the error magnitude to 1LSB.

The analog input is designed for either differential or single- ended use with a ±250mV input voltage range. Dual, differential, PECL-compatible output data paths ensure easy interfacing and include an 8:16 demultiplexer feature that reduces output data rates to one-half the sampling clock rate. The PECL outputs can be operated from any supply between +3V to +5V for compatibility with +3.3V or +5V referenced systems. Control inputs are provided for
interleaving additional MAX106 devices to increase theeffective system sampling rate.

The MAX106 is packaged in a 25mm x 25mm, 192-contact Enhanced Super-Ball-Grid Array (ESBGA™), and is specified over the commercial (0°C to +70°C) temperature range. For a pin-compatible higher speed upgrade, refer to the MAX104 (1Gsps) and MAX108 (1.5Gsps) data sheets.
