IQXO-331, -336 CLOCK OSCILLATORS
ISSUE 9; 3 APRIL 2009 - RoHS 2002/95/EC
Description
ACMOS/TTL 14-pin DIL compatible resistance welded
enclosure, hermetically sealed with glass to metal seal
Package Outline
14-pin DIL
Frequency Range
70MHz to 150MHz
Output Compatibility & Load
ACMOS/TTL
Drive Capability:
50pF max (70.0 to 110.0MHz)
15pF max (>110.0 to 150.0MHz)
10TTL
Non tri-state (IQXO-336, -336I)
Tri-state (IQXO-331, 331I)
Frequency Stabilities
±25ppm, ±50ppm, ±100ppm (over operating temperature
range)
Operating Temperature Ranges
0 to 70°C (IQXO-331, -336)
–40 to 85°C (IQXO-331I, -336I)
Storage Temperature Range
–55 to 125°C
Tri-state Operation (IQXO-331, -331I)
No connection or Logic ‘1’ to pin 1 enables oscillator output
Logic ‘0’ to pin 1 disables oscillator output; when disabled the
oscillator output goes to the high impedance state
Maximum ‘pull-down’ resistance required to disable output
= 20k
