The 8T49N285 has one fractional-feedback PLL that can be used as a frequency translator with jitter attenuation or a frequency synthesizer. It is equipped with six integer and two fractional output dividers, allowing the generation of up to eight different output frequencies, ranging from 8 kHz to 1 GHz. Output frequencies can be completely independent of the input frequencies, and up to three of these frequencies can be completely independent of each other. The eight outputs may select among LVPECL, LVDS, HCSL or LVCMOS output levels.
- Supports GR.1244 Stratum 3 stability in holdover mode
- Compliant with the requirements outlined in Telcordia GR-253-CORE (SONET) & ITU-T G.813/G.8262 (SDH/SONET & SyncE) when paired with a Synchronous Equipment Timing Source (SETS ) device
- Generates up to 8 LVPECL / LVDS/HCSL or 16 LVCMOS output clocks ranging from 8 kHz up to 1.0 GHz (diff), 8 kHz to 250 MHz (LVCMOS), that meet jitter limits for 10G up to 100G Ethernet and STM-256/OC-768 applications
- 0.3ps RMS (including spurs), 12 kHz to 20 MHz
- Accepts up to two LVPECL, LVDS, LVHSTL, HCSL or LVCMOS input clocks ranging from 8 kHz up to 875 MHz
- Auto and manual input clock selection with hitless switching
- Clock input monitoring, including support for gapped clocks
- Phase-Slope Limiting and Fully Hitless Switching options to control output phase transients
- Operates from a 10 MHz to 40 MHz fundamental-mode crystal
- Register programmable through I2C / SPI or via external I2C EEPROM
- 8T49N285-998 “Boot from EEPROM”
- 8T49N285-999 “powers up disabled”
- Supported by IDT Timing Commander Software
