SY89430V中文资料Clock Generators Clock Synthesizers Products数据手册Microchip规格书

描述 Description

NOT RECOMMENDED FOR NEW DESIGNThe SY89430V is a general purpose, synthesized clock source targeting applications that require both serial and parallel interfaces. Its internal VCO will operate over a range of frequencies from 400 to 950MHz. The differential PECL output can be configured to be the VCO frequency divided by 1, 2, 4 or 8. With the output configured to divide the VCO frequency by 2, and with a 16MHz external quartz crystal used to provide the reference frequency, the output frequency can be specified in 1MHz steps.

特性 Features

• 3.3V and 5V power supply options
• 50MHz to 950MHz differential PECL outputs
• ±25ps peak-to-peak output jitter
• Minimal frequency over-shoot
• Synthesized architecture
• Serial 3 wire interface
• Parallel interface for power-on
• Internal quartz reference oscillator driven by quartz crystal
• External loop filter optimizes performance/cost
• Applications note (AN-07) for ease of design-ins
• Available in 28-pin PLCC and SOIC packages
