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 VCXO pull range must be specified at the
time of order and are programmed by IDT before the shipment. Table
1 specifies the available order codes including the device options.
Table 2 to Table 4 specify the default frequency configurations.
Example part number: order code 8N3QV01FD-0001CDI specifies a
programmable, quad default-frequency VCXO with a voltage supply
of 2.5V, a LVPECL output, a
50ppm
crystal frequency accuracy,
contains a 114.285MHz internal crystal as frequency source,
industrial temperature range, a lead-free (6/6 RoHS) 10-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 min.
100ppm.
The
default frequency configuration is found in table 1.
Other default frequencies and order codes are available from IDT on
request.
Look up default frequencies from Tables 2, 3 and 4 by using the
left-most frequency column for single-frequency devices, the two
left-most columns for dual and all four columns for quad-frequency
devices, respectively.
