The AD9524 provides a low power, multi-output, clock distribution function with low jitter performance, along with an on-chip PLL and VCO. The on-chip VCO tunes from 3.6 GHz to 4.0 GHz.The AD9524 is designed to support the clock requirements for long term evolution (LTE) and multicarrier GSM base station designs. It relies on an external VCXO to provide the reference jitter cleanup to achieve the restrictive low phase noise requirements necessary for acceptable data converter SNR performance.The input receivers, oscillator, and zero delay receiver provide both single-ended and differential operation. When connected to a recovered system reference clock and a VCXO, the device generates six low noise outputs with a range of 1 MHz to 1 GHz, and one dedicated buffered output from the input PLL (PLL1). The frequency and phase of one clock output relative to another clock output can be varied by means of a divider phase select function that serves as a jitter-free coarse timing adjustment in increments that are equal to one-half the period of the signal coming out of the VCO.An in-package EEPROM can be programmed through the serial interface to store user-defined register settings for power-up and chip reset.APPLICATIONS LTE and multicarrier GSM base stations Wireless and broadband infrastructure Medical instrumentation Clocking high speed ADCs, DACs, DDSs, DDCs, DUCs, MxFEs Low jitter, low phase noise clock distribution Clock generation and translation for SONET, 10Ge, 10G FC, and other 10 Gbps protocols Forward error correction (G.710) High performance wireless transceivers ATE and high performance instrumentation

The ADM1293 and ADM1294 are high accuracy integrated digital power monitors that offer digital current, voltage, and power monitoring using an on-chip, 12-bit analog-to-digital converter (ADC), communicated through a PMBus™ compliant I2C interface.These devices acquire the current by measuring the voltage difference across the external sense resistor. This voltage is amplified and digitized by an internal 12-bit ADC. The same ADC can also sample the primary input voltage and an auxiliary input voltage. The internal digital block can perform multiplication of the current and primary input voltage for power calculation. The ADM1293/ADM1294 also feature a power accumulator for energy metering. An industry-standard PMBus interface allows a master controller to read back these data from the device. The master controller can then combine this information with a known sense resistor value to calculate the current, voltage, power, and energy consumption over time on the monitored rail.In conditions such as overcurrent, overvoltage, undervoltage, and overpower, the ADM1293/ADM1294 devices can generate an interrupt signal to the microprocessor through the GPOx/ALERTx outputs. The threshold for these conditions is digitally programmed via PMBus.The ADM1293 is designed for high-side supply monitoring with a voltage monitoring range from 0 V to 20 V.
