DESCRIPTION

· The LMK61E08 is an ultra-low jitter PLLatinum™ programmable oscillator with integrated VCOs for generating reference clocks.

· It supports output formats including LVPECL, LVDS, and HCSL.

· Features self-start-up from on-chip EEPROM with factory-programmed default output frequency.

· Fully programmable in-system through an I2C serial interface.

· Provides fine and coarse frequency margining control, functioning as a digitally-controlled oscillator (DCXO).

FEATURES

· Ultra-Low Noise, High Performance: Jitter of 90-fs RMS typical for fOUT >100MHz.

· Flexible Output Format: Supports LVPECL up to 1GHz, LVDS up to 900MHz, HCSL up to 400MHz.

· Total Frequency Tolerance: ±25ppm.

· System Level Features: Glitch-less frequency margining up to ±1000 ppm from nominal, internal EEPROM for user configurable start-up settings.

· Device Control: Fast Mode I2C up to 1000 kHz, 3.3-V Operating Voltage, Industrial Temperature Range (-40ºC to +85ºC), 7-mm × 5-mm 6-Pin Package.

· Default Frequency: 70.656 MHz.

APPLICATIONS

· High-Performance Replacement for Crystal, SAW, or Silicon-Based Oscillators.

· Switches, Routers, Network Line Cards, Base Band Units (BBU), Servers, Storage/SAN.

· Test and Measurement, Medical Imaging, FPGA, Processor Attach, xDSL, Broadcast Video.
