Features & Applications

The MC100EP44 Series are an integrated 8-bit differential serial to parallel data converter with frame asynchronous data resynchronization. The device is designed to operate for NRZ data rates of up to 2.5 Gb/s. The conversion sequence was chosen to convert the first serial bit to Q0, the second bit to Q1, etc. Two selectable differential serial inputs, which are selected by SINSEL, provide this device with loop-back testing capability.

The MC100EP445 has a Sync pin which, when held high for at least two consecutive clock cycles, will swallow one bit of data shifting the start of the conversion data from Dn to Dn+1. Each additional shift requires an additional pulse to be applied to the Sync pin.Extra control pins are provided to reset and disable internal clock circuitry. Additionally, VBB pin is provided for single-ended input condition.The 100 Series contains temperature compensation.

Key Features:

  • 300 ps Propagation Delay
