P521-39 Datasheet

P521-39 Low Phase Noise PECL VCXO

P521-39 is a VCXO IC specifically designed to pull high frequency fundamental crystals. Its internal varicaps allow an on chip frequency pulling, controlled by the VCON input. The chip provides a low phase noise, low jitter LVDS differential clock output. X DIE SPECIFICATIONS Name Size Reverse si.
