Product Details

The HMC6832 is an input selectable, 2:8 differential fanout buffer designed for low noise clock distribution. The IN_SEL control pin selects one of the two differential inputs. This input is then buffered to all eight differential outputs. The low jitter outputs of the HMC6832 lead to synchronized low noise switching of downstream circuits, such as mixers, analog-todigital converters (ADCs)/digital-to-analog converters (DACs), or serializer/deserializer (SERDES) devices. The device is capable of low voltage, positive emitter-coupled logic (LVPECL) or low voltage differential signaling (LVDS) configurations by pulling the CONFIG pin low for LVPECL or high or open (internally pulled high) for pseudo LVDS.

Product Highlights

  1. Multiple Output Configurations.
    The CONFIG pin allows the user to select LVPECL or LVDS output termination.
  2. Multiple Supply Voltage Operation.
    The HMC6832 operates at 2.5 V or 3.3 V for LVPECL terminations (2.5 V only for LVDS).
  3. Low Noise.
    The HMC6832 noise is low, typically from −168 dBc/Hz to −162 dBc/Hz up to 3000 MHz.
  4. Low Propagation Delay.
    The HMC6832 displays a low delay, less than 207 ps, typical. Channel skew is also low, ±5 ps, typical.
  5. Low Core Current.
    The HMC6832 has a low core current of 56 mA, typical.
