IDT8N3DV85 Data Sheet LVPECL DUAL-FREQUENCY PROGRAMMABLE VCXO
Ordering Information for FemtoClock NG Ceramic-Package XO and VCXO Products
The programmable VCXO and XO devices support a variety of
devices options such as the output type, number of default frequen-
cies, internal crystal frequency, power supply voltage, ambient
temperature range and the frequency accuracy. The device options,
default frequencies and default VCXO pull range must be specified
at the time of order and are programmed by IDT before the shipment.
The table below specifies the available order codes, including the
device options and default frequency configurations. Example part
number: the order code 8N3QV01FG-0001CDI specifies a
programmable, quad default-frequency VCXO with a voltage supply
of 2.5V, a LVPECL output, a 50 ppm crystal frequency accuracy,
contains a 114.285MHz internal crystal as frequency source,
industrial temperature range, a lead-free (6/6 RoHS) 6-lead ceramic
5mm x 7mm x 1.55mm package and is factory-programmed to the
default frequencies of 100MHz, 122.88MHz, 125MHz and
156.25MHz and to the VCXO pull range of minimum 100 ppm.
Other default frequencies and order codes are available from IDT on
requ
est. For more information on available default frequencies, see
the FemtoClock N Ceramic-Package XO and VCXO Ordering
Product Information document.
