The ADCMP563/ADCMP564 are high speed comparatorsfabricated on Analog Devices’ proprietary XFCB process. Thedevices feature a 700 ps propagation delay with less than 75 psoverdrive dispersion. Dispersion, a measure of the difference inpropagation delay under differing overdrive conditions, is a particularlyimportant characteristic of high speed comparators. A separateprogrammable hysteresis pin is available on the ADCMP564.A differential input stage permits consistent propagation delaywith a wide variety of signals in the common-mode range from−2.0 V to +3.0 V. Outputs are complementary digital signals thatare fully compatible with ECL 10 K and 10 KH logic families.The outputs provide sufficient drive current to directly drivetransmission lines terminated in 50 Ω to −2 V. A latch input,which is included, permits tracking, track-and-hold, or sample-and-holdmodes of operation. The latch input pins contain internalpull-ups that set the latch in tracking mode when left open.The ADCMP563/ADCMP564 are specified over the industrialtemperature range (−40°C to +85°C).Applications Automatic test equipment High speed instrumentation Scope and logic analyzer front ends Window comparators High speed line receivers Threshold detection Peak detection High speed triggers Patient diagnostics Hand-held test instruments Zero crossing detectors Line receivers and signal restoration Clock drivers

The ADF4116/ADF4117/ADF4118 are frequency synthesizers which can be used to implement local oscillators in the up-conversion and down-conversion sections of wireless receivers and transmitters. Theyconsist of a low-noise digital PFD (Phase Frequency Detector), a precision charge pump, a programmable reference divider, programmable A and B counters and a dual-modulus prescaler (P/P+1). The A (5-bit)and B (13-bit) counters, in conjunction with the dual modulus prescaler (P/P+1), implement an N divider (N= BP+A). In addition, the 14-bit reference counter (R Counter), allows selectable REFIN frequencies at the PFD input. A complete PLL (Phase-LockedLoop) can be implemented if the synthesizer is used with an external loop filter and VCO (Voltage Controlled Oscillator).Control of all the on-chip registers is via a simple 3-wire interface.The devices operate with a 2.7V (± 10%) or 5V (± 10%) power supply and can be powered when not in use.

The ADG528A and ADG529A are CMOS monolithic analogmultiplexers with eight channels and four dual channels, respectively.On-chip latches facilitate microprocessor interfacing. TheADG528A switches one of eight inputs to a common output,depending on the state of three binary addresses and an enableinput. The ADG529A switches one of four differential inputs toa common differential output, depending on the state of twobinary addresses and an enable input. Both devices have TTLand 5 V CMOS logic-compatible digital inputs.The ADG528A and ADG529A are designed on an enhancedLC2MOS process, which gives an increased signal capability ofVSS to VDD and enables operation over a wide range of supplyvoltages. The devices can comfortably operate anywhere in the10.8 V to 16.5 V single- or dual-supply range. Thesemultiplex-ers also feature high switching and low RON.The ADG529A is no longer available.Product Highlights Single-/dual-supply specifications with a wide tolerance. The devices are specified in the 10.8 V to 16.5 V range for both single- and dual-supplies. Easily Interfaced The ADG528A and ADG529A can be easily interfaced with microprocessors. The WR signal latches the state of the address control lines and the enable line. The RS signal clears both the address and enable data in the latches resulting in no output (all switches off). RS can be tied to the microprocessor reset pin. Extended Signal Range The enhanced LC2MOS processing results in a high breakdown and an increased analog signal range of VSS to VDD. Break-Before-Make Switching Switches are guaranteed break-before-make so that input signals are protected against momentary shorting. Low Leakage Leakage currents in the range of 20 pA make these multiplexers suitable for high precision circuits.
