Figure 1. PECL Operation
Figure 2. ECL Operation
1. By setting OD low, a test signal may be applied at CLKIN and fed through the VCO-600A to both the CLKOUT and CLKOUT to facilitate on board
testing. The test signal input applied at CLKIN may be either an ECL or sinewave input (up to 1Vpp, AC coupled). CLKIN is biased internally to
VBB (Vcc-1.3V)
2. An optional capacitor to ground can be placed on VBW to reduce the modulation bandwidth for narrow bandwidth phase-lock loop applications. The
modulation bandwidth will be approximately 1/(12000*C) Hz, where C is equal to the capacitance in Farads. If the optional capacitor is not utilized, VBW
becomes a no connect (NC) and the modulation bandwidth will be approximately equal to the nominal device frequency
÷1200.
3. By setting OD low, the outputs are disabled and CLKOUT is held Low while CLKOUT is held High. The threshold for OD is 1.4V above VEE. OD
should not be driven above mid supply and during normal operation, should be left floating (use with an open collector or 3-State gate for interfacing with
standard logic). If the OD feature is used during normal operation, then CLKIN should be tied through 10K
to GND to avoid any possibility of chatter on
the CLKOUT outputs
