813N252I-09
Description
The 813N252I-09 is a PLL based synchronous multiplier that is optimized for PDH or SONET to Ethernet clock jitter attenuation and frequency translation.
Key Features
- Two LVPECL output pairs Each output supports independent frequency selection at 25MHz, 125MHz, 156.25MHz and 312.5MHz
- Two differential inputs support the following input types: LVPECL, LVDS, LVHSTL, SSTL, HCSL
- Attenuates the phase jitter of the input clock by using a low-cost pullable fundamental mode VCXO crystal
- VCXO PLL bandwidth can be optimized for jitter attenuation and reference tracking using external loop filter connection
- FemtoClock frequency multiplier provides low jitter, high frequency output
- Absolute pull range: 50ppm
- FemtoClock VCO frequency: 625MHz
- RMS phase jitter @ 125MHz, using a 25MHz crystal (12kHz - 20MHz): 0.25ps (typical) and 0.35ps (maximum)
- 3.3V supply voltage
- 40°C to 85°C ambient operating temperature
