ADN4670:  Programmable Low Voltage 1:10 LVDS Clock Driver

Product Details

Product Status:Recommended for New Designs

The ADN4670 is a low voltage differential signaling (LVDS) clock driver that expands a differential clock input signal to 10 differential clock outputs. The device is programmable using a simple serial interface, so that one of two clock inputs can be selected (CLK0/CLK0 or CLK1/CLK1) and any of the differential outputs (Q0/Q0 to Q9/Q9) can be enabled or disabled (tristated). The ADN4670 is designed for use in 50 Ω transmission line environments.

When the enable input EN is high, the device may be pro-grammed by clocking 11 data bits into the shift register. The first 10 bits determine which outputs are enabled (0 = disabled, 1 = enabled), while the 11th bit selects the clock input (0 = CLK0, 1 = CLK1). A 12th clock pulse transfers data from the shift register to the control register.

The ADN4670 is fully specified over the industrial temperature range and is available in a 32-lead LFCSP package.

  • Clock distribution networks

    • Low output skew <30 ps (typical)
    • Distributes one differential clock input to 10 LVDS clock outputs
    • Programmable—one of two differential clock inputs can be selected (CLK0, CLK1) and individual differential clock outputs enabled/disabled
    • Signaling rate up to 1.1 GHz (typical)
    • 2.375 V to 2.625 V power supply range
    • ±100 mV differential input threshold
    • Input common-mode range from rail-to-rail
    • I/O pins fail-safe during power-down: VDD = 0 V
    • Available in 32-lead LFCSP package
    • Industrial operating temperature range: −40°C to +85°C
