LMK61E2-SIAT Datasheet PDF - TI

●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

●This device has limited built-in ESD protection. The leads should be shorted together or place the device in conductive foam during storage or handling to prevent electrostatic damage to MOS gates.
