5P49EE502-166
5P49EE502-166 is Low-Power Clock Generator manufactured by Renesas.
escription
The 5P49EE502-166 is a programmable clock generator intended for low-power, battery-operated applications. There are 4 individually programmable PLLs connected to 5 outputs, allowing up to 5 different output frequencies. All PLLs are driven from a mon reference clock which can e from a crystal or an external oscillator. The IDT5P49EE502 datasheet contains detailed information on how to configure this device.
Typical Applications
- Battery-powered, portable devices
Output Features
- 5 single-ended LVTTL/LVCMOS outputs
- 2 VDDO rails support 1.8V, 2.5V, 3.3V output swing
- Each output can be connected to either of the 2 VDDO rails
