IDT8N4QV01 REV G DATA SHEET

QUAD-FREQUENCY PROGRAMMABLE-VCXO

NOTE: Electrical parameters are guaranteed over the specified ambient operating temperature range, which is established when the device is

mounted in a test socket with maintained transverse airflow greater than 500 lfpm. The device will meet specifications after thermal equilibrium

has been reached under these conditions. All AC parameters are characterized with P=1 and pull range ±250 ppm.

NOTE: XTAL parameters (initial accuracy, temperature stability, aging and total stability) are guaranteed by manufacturing.

NOTE 1: This parameter is defined in accordance with JEDEC standard 65.

NOTE 2: Please refer to the phase noise plots.
