The Detection Integrator can also be viewed as a 'consensus' filter, that requires four detections in four successive bursts to create an output. As the basic burst spacing is 75ms, if this spacing was maintained throughout all 4 counts the sensor would react very slowly. In the Q14000B, after an initial detection is sensed, the remaining three bursts are spaced about 18ms apart, so that the slowest reaction time possible is 75+18+18+18 or 129ms and the fastest possible is 54ms, depending on where in the initial burst interval the contact first occurred. The response time will thus average 92ms.
The Q14000B provides high security, low cost, and ease of implementation with- out the need for a microprocessor operating system. The embedded cryptographic engine provides for dynamic, symmetric-mutual authentication between the device and host, as well as performing stream encryption for all data and passwords exchanged between the device and host. Up to four unique key sets may be used for these opera- tions. The Q14000B offers the ability to communicate with virtually any smart card reader using the asynchronous T = 0 protocol (Gemplus Patent) defined in ISO 7816-3. Communication speeds up to 153,600 baud are supported by utilizing ISO 7816-3 Protocol and Parameter Selection.
The Q14000B is a monolithic 8-bit, 250Msps analog-to- digital converter (ADC) optimized for outstanding dynamic performance at high IF frequencies up to 500MHz. The product operates with conversion rates of up to 250Msps while consuming only 477mW. At 250Msps and an input frequency of 100MHz, the Q14000B achieves a spurious-free dynamic range (SFDR) of 68dBc. Its excellent signal-to-noise ratio (SNR) of 48.9dB at 10MHz remains flat (within 0.5dB) for input tones up to 500MHz. This makes the Q14000B ideal for wideband applications such as digital predis- tortion in cellular base-station transceiver systems. The Q14000B requires a single 1.8V supply. The ana- log input is designed for either differential or single- ended operation and can be AC- or DC-coupled. The ADC also features a selectable on-chip divide-by-2 clock circuit, which allows the user to apply clock fre- quencies as high as 500MHz. This helps to reduce the phase noise of the input clock source. A differential LVDS sampling clock is recommended for best perfor- mance. The converters digital outputs are LVDS com- patible, and the data format can be selected to be either twos complement or offset binary. The Q14000B is available in a 68-pin QFN with exposed paddle (EP) and is specified over the industri- al (-40C to +85C) temperature range. For pin-compatible, higher resolution versions of the Q14000B, refer to the MAX1122 (170Msps), the MAX1123 (210Msps), and the MAX1124 (250Msps) data sheets.
