| Clock/Timing | 4 | Obsolete | The 501A is the most cost effective way to generate a high quality, high frequency clock output from a lower frequency crystal or clock input. 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 200 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). The device also has an output enable pin which tri-states the clock output when the OE pin is taken low. 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. |

502Loco™ PLL Clock Multiplier | Integrated Circuits (ICs) | 4 | Obsolete | The 502 Loco™ is the most cost effective way to generate a high-quality, high-frequency clock output and a reference 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 six 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. |
508PECL to CMOS Converter | Integrated Circuits (ICs) | 2 | Obsolete | The 508 is the most cost effective way to generate a high quality, high frequency CMOS clock output from a PECL clock input. The 508 has separate VDD supplies for the PECL input buffer and the output buffer, allowing different voltages to be used. For example, the input clock could use a 3.3 V supply while the output operates from 2.5V. The device has an Output Enable pin that tri-states the clock output when the OE pin is taken low. The 508 is a member of IDT's ClockBlocksTM family. |
