Oscillator Frequency Upconverter

GENERAL DESCRIPTION The AD9552 is a fractional-N phase locked loop (PLL) based clock generator designed specifically to replace high frequency crystal oscillators and resonators. The device employs a sigma-delta (Σ-Δ) modulator (SDM) to accommodate fractional frequency synthesis. The user supplie

16-bit I2C LED driver with programmable blink rates

DESCRIPTION The PCA9552 LED Blinker blinks LEDs in I2C-bus and SMBus applications where it is necessary to limit bus traffic or free up the I2C Master’s (MCU, MPU, DSP, chipset, etc.) timer. The uniqueness of this device is the internal oscillator with two programmable blink rates. To blink LEDs

PIN DIODE ATTENUATOR

Description The UM9552 is a very long minority carrier lifetime (70 ms typical) PIN DIODE that has been developed for low HF or LF Band Attenuator Applications. They have been evaluated for attenuator linearity and distortion characteristics in a Bridge Tee Attenuator Circuit at 455 KHz (the comm
