MAX106 pdf
19-1486; Rev 1; 11/01
±5V, 600Msps, 8-Bit ADC with On-Chip
2.2GHz Bandwidth Track/Hold Amplifier
General Description
The MAX106 PECL-compatible, 600Msps, 8-bit analog-to-
digital converter (ADC) allows accurate digitizing of ana-
log 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-of-
sequence 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 out-
puts, the MAX106 limits the error magnitude to 1LSB.
The analog input is designed for either differential or sin-
gle-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 the
effective system sampling rate.
The MAX106 is packaged in a 25mm x 25mm, 192-con-
tact 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.
