V C X O Logic: PECL square wave “GPL” series (PLL based PECL)

VCXO
“GPL” series (PLL based PECL)
Logic: PECL square wave
MERCURY
Since 1973
“GPL” series VCXOs, based on phase lock loop technique, provide low cost alternative to differential PECL output
with 12.5 ps RMS jitter for non-jitter sensitive applications.
