Configurable High Performance SMD TCXO/VCTCXO
ASGTX
OVERVIEW:
ASGTX
temperature compensated
Crystal
Oscillators are designed to accommodate a broad breadth of
Precision
TCXO
requirements, without
NRE
and extended lead-times. This oscillator series is designed and
manufactured
by
Abracon Corporation and is available to order from 1pc to high volume production
quantities.

•
1-5 day quick-turn availability of a TCXO/VCTCXO with LVCMOS output, Any frequency
between 10MHz & 250MHz
For example, if a reference oscillator requirement calls out 49.7521MHz; ±1.00
ppm
TCXO/VCTCXO
with
LVCMOS
output,
ASGTX
can be configured and shipped within 1-5 days and in most cases,
same day if order is received before noon. Customers with low-to-mid annual volume requirements
find it difficult to procure custom frequency TCXO/VCTXCO’s without costly
NRE
charges and/or
long lead-times (>
12
weeks).
•
1-5 day quick turn availability of a TCXO/VCTXCO requiring LVDS or LVPECL Differential
output, Any frequency between 10MHz to 1.50GHz
ASGTX
is available with either
LVDS or LVPECL
output, from
10MHz to 1.50GHz;
at any desired
frequency, such as 149.875MHz, 1.00GHz, 1.5GHz, etc. with as tight as
±1.00 ppm
stability over
temperature. No other solution in the marketplace currently offers such capability, especially in a small
form-factor of 9.0x7.0x2.24 mm.
ASGTX
is suitable for a wide variety of precision timing applications where TCXO/VCTXO’s are typically
employed. In addition, for high
frequency
LO requirements, traditionally customers have relied on SAW
based oscillators. Such devices are only available at a few fixed frequencies, such as 915MHz, 1.0GHz,
etc. They are typically in 9x14mm or bigger packages and vary as much as ±100 ppm over temperature.
Although
ASGTX
series will be slightly less favorable in phase noise performance compared to
SAW
based
oscillators, it offers the following key advantages:
o ±1.00
ppm
stability over -30ºC to
+70ºC
&
±2.00 ppm stability over -40ºC to +85ºC
o
Any carrier frequency
between 10MHz & 1.50GHz
o LVCMOS Output (10MHz to 250MHz)
or
LVDS / LVPECL Output (10MHz to 1.50GHz)
o
Small
form-factor of 9.0x7.0x2.24 mm
o No NRE or
lead-time
• 10MHz to 1.50GHz, any Carrier Frequency in differential mode
(LVDS or LVPECL)
• 10MHz to 250MHz, any Carrier Frequency in LVCMOS mode
• -40ºC to +85ºC operating temperature range
• ±1.0ppm stability over -30ºC to +70ºC and ±2.0ppm stability over
-40ºC to +85ºC
• Minimum guaranteed pull ability of ± 10ppm in VCTCXO mode
• Good Phase Noise, excellent Harmonics and Spurious content
• Guaranteed rms jitter of 1.80ps maximum @ 1.50GHz carrier (LVDS mode)
• Immediate availability, 5-day maximum lead-time for small quantities
FEATURES:
• 40G & 100G Ethernet
• WiMax,
• LTE, BTS
• CATV, LAN, LMDS
• Point-to-Point communication networks
