ICD2051 Overview
The ICD2051 Programmable Clock Generator offers two fully user-programmable phase-locked loops in a single package. The outputs may be changed “on the fly” to any desired frequency value between 320 kHz and 100 MHz. The ICD2051 is ideally suited for any design where one or more multiple or varying frequencies are required, thus replacing more expensive metal can oscillators.
ICD2051 Key Features
- Two independent clock outputs ranging from 320 kHz to 100 MHz
- Individually programmable PLLs use 22-bit serial word
- Low-skew ÷1,÷2, and ÷4 CLKA outputs
- Phase-locked loop oscillator input derived from external low-frequency reference clock (1 MHz
- 25 MHz) or external crystal (2 MHz
- 24 MHz)
- Sophisticated internal loop-filter requires no external .. ponents or manufacturing tweaks as monly required with extern
- Three-state control disables outputs for test purposes (optional)
- 5V operation
- Low-power, high-speed CMOS technology
