PLL130-69 Datasheet | PhaseLink Corporation

FEATURES Differential PECL (PLL130-68) or LVDS (PLL130-69) output. - Accepts any single-ended REFIN input (with as low as 100m V swing). - Internal AC coupling of REFIN - Input range from 1.0MHz to 1.0 GHz. - No Vref required. .. - No external current source required. - 2.5 to 3.3V operation. - Available in 3x3mm QFN. - PIN CONFIGURATION (TOP VIEW) Q_bar VDD NC REFIN NC NC 1 2 3 4 12 11 10 9 NC Q Q_bar OESEL PLL130-6x 5 6 7 8 DESCRIPTION The PLL130-68 and PLL130-69 are low cost, high performance, high speed, translator buffers that reproduce any input frequency from DC to 1.0GHz. They provide a pair of differential outputs (PECL for PLL130-68 or LVDS for PLL13069). Thanks to an internal AC coupling of the reference input (REFIN), any input signal with at least 100m V swing can be used as reference signal, regardless of its DC value. These chips are ideal for conversion from clipped sine wave, TTL, CMOS, or differential signal to LVDS or PECL.
