NJU6323

The NJU6323 series  is  a C-MOS quartz crystal oscillator which consists of an oscillation  amplifier,3-stage divider, output frequency  selector and 3-state output buffer.The oscillation  frequency of NJU6323  is as wide as up to 50MHz and the symmetry of 45-55% is realized over full oscillation frequency range.The oscillation amplifier incorporates  feed-back resistance and oscillation capacitors(Cg, Cd),therefore,NJU6323 requires no external component except quartz crystal.The  3-stage  divider outputs fo, fo/2, fo/4 and fo/8 to the  output frequency selector and it determined one output frequency  according to  the  combination of two input-signal.The 3-state output  buffer is  C-MOS  compatible  and capable of 10 LSTTL driving.

Features of the NJU6323 are:(1)operating voltage:3.0~6.0V; (2)maximum oscillation frequency :50MHz; (3)low operating current; (4)high fan-out:TTL 10; (5)3-state output buffer; (6)selected frequency output(mask option):only one frequency of fo, fo/2, fo/4 and fo/8 output; (7)oscillation and/or outaut stand-by function; (8)package outline:CHIP/EMP 8; (9)C-MOS technology;(10)oscillation capacitors Cg and Cd on-chip.

The absolute maximum ratings of the NJU6323 can be summarized as:(1)supply voltage:-0.5 to +7.0V;(2)storage temperature range:-65 to +150;(3)operating temperature range:-40 to +85 ;(4)input voltage:-0.5V to Vdd+0.5V;(5)output voltage:-0.5V to Vdd+0.5V;(6)input current:±10mA;(7)output current:±25mA;(8)power dissipation:200mW.The products described in this document are designed, developed and manufactured as contemplated for general use, including without limitation, ordinary industrial use, general office use, personal use, and household use, but are not designed, developed and manufactured as contemplated (1) for any use that includes fatal risks or dangers that, unless extremely high safety is secured, could have a serious effect to the public, and could lead directly to death, personal injury, severe physical damage or other loss (i.e., nuclear reaction control in nuclear facility, aircraft flight control, air traffic control, mass transport control, medical life support system, missile launch control in weapon system), or (2) for any use where chance of failure is intolerable (i.e., submersible repeater and artificial satellite).
