FEATURES

  • Differential PECL output
  • Single AC coupled input (min. 100mV swing).
  • Input range from DC to 1.0 GHz.
  • 2.5V to 3.3V operation.
  • Available in 3x3mm QFN.

DESCRIPTION

The PLL130-05 is a low cost, high performance, high speed, buffer that reproduces any input fre- quency from DC to 1.3GHz. It provides one pair of differential PECL outputs. Any input signal with at least 100mV swing can be used as refer- ence signal. This chip is ideal for conversion from sine wave, TTL, CMOS, or LVDS to PECL.
