Description

The 503 is a member of the Loco™ family, the most cost effective way to generate a high-quality, high frequency clock output from a lower frequency crystal or clock input. The name LOCO stands for Low Cost Oscillator, as it is designed to replace crystal oscillators in most electronic systems. Using Phase-Locked-Loop (PLL) techniques, the device uses a standard fundamental mode, inexpensive crystal to produce output clocks up to 160 MHz. Stored in the chip's ROM is the ability to generate nine different multiplication factors, allowing one chip to output many common frequencies (see table on page 2). This product is intended for clock generation. It has low output jitter (variation in the output period), but input to output skew and jitter are not defined or guaranteed. For applications which require defined input to output skew, use the 570B.

  1. ZMOD4510 Stopping measurements

    Hi, what is the correct way to stop the ZMOD4510 measurements and then restart? It is necessary to init the sensor and the library again in order to reset the data structures? Thanks

  3. ISL71831SEH input over voltage protection

    The ISL71831 has input over voltage protection. Does this include overvoltage in both directions? I.e.: protection above V+ and protection below GND?
