Description
LMFX_DXXX is a series of frequency translators, using PLL technique to translate one of two different input
frequencies from 1MHz and up, to one of two output frequencies from 77.76MHz to 777.6MHz.
The LMFX_DXXX unit supports all FEC rates and it also supports switching from OC-n to 10GigE and 10G to 10.3125G.
Up to 4 different input frequencies could be locked to a high quality SAW or Crystal voltage controlled oscillators.
Feature
- Single 5V or 3.3V power supply
- Comp. PECL input signal
- Comp. PECL output
- Low output jitter
- Lock signal alarm
- Control voltage monitor output
- 1.2" x 1.0" x 0.25" Surface Mount Package.
Application
SONET/SDH, DWDM, FDM, ATM
