OE
Output Enable. On-chip pullup resistor. Connect OE to logic-high, VCC, or leave open to enable the
output clock. Connect OE to logic-low or GND to disable the output clock. The LVPECL output
clock is set to high impedance when disabled. The LVDS output clock is latched to a differential
high when disabled.

Detailed Description
The DS4106/DS4212/DS4425 combine a crystal and an
IC to form a precision clock. Figure 1 shows a function-
al diagram of the devices. The IC consists of a crystal
oscillator, a low-noise PLL, selectable clock-divider cir-
cuitry, and an output buffer. The PLL consists of a digi-
tal phase/frequency detector (PFD) and low-jitter
generation VCO. The VCO signal is scaled by a clock-
divider circuit and applied to the output buffer.
Output Drivers
All devices are available with either LVPECL
(DS4106A/DS4212A/DS4425A) or LVDS (DS4106B/
DS4212B/DS4425B) output buffers. When not needed,
the output buffers can be disabled. When disabled, the
LVPECL output buffer goes to a high-impedance state.
However, the LVDS outputs go to a differential logic
one (OUTP latched high and OUTN latched low) when
the outputs are disabled.
