Программируемые генераторы LMK61E2-SIAT

Кварцевый генератор и генератор импульсов , крайне маленький джиттер, 1.05ГГц, 3.135В - 3.465В, QFM-8

The LMK61E2-SIAT is an ultra low programmable oscillator with internal EEPROM in 8 pin QFM package. The LMK61E2-SIAT is an ultra low jitter platinum programmable oscillator with a fractional-N frequency synthesizer with integrated VCO that generates commonly used reference clocks. The outputs can be configured as LVPECL or LVDS or HCSL. It features self start-up from on-chip EEPROM that is factory programmed to generate 156.25MHz LVPECL output. The device registers and EEPROM settings are fully programmable in-system via I2C serial interface. Internal power conditioning provide excellent power supply ripple rejection (PSRR), reducing the cost and complexity of the power delivery network. The device operates from a single 3.3V ±5% supply. It provides fine and coarse frequency margining options via I2C serial interface to support system design verification tests (DVT) such as standard compliance and system timing margin testing.

• 90fs RMS jitter at Fout < 100MHz
• PSRR is -70dBc and robust supply noise immunity
• Total frequency tolerance of ±50ppm
• Industrial temperature range from -40°C to +85°C
• ESD protection of ±2KV human body model (HBM) and ±500V charged device model (CDM)
• User selectable LVPECL up to 1GHz, LVDS up to 900MHz & HCSL up to 400MHz flexible output format
