description
The CDC857-2 and CDC857-3 are high-performance, low-skew, low-jitter, phase-lock loop
(PLL) clock driver. They use a PLL to precisely
align, in both frequency and phase, the feedback
(FBOUT) output to the clock (CLK) input signal.
The CDC857-3 operates at 3.3 V (PLL) and 2.5 V
(output buffer). The CDC857-2 operates at
2.5 V (PLL and output buffer).

One bank of ten inverting and noninverting

outputs provide ten low-skew, low-jitter copies of
24
25
CLK. Output signal duty cycles are adjusted to
50%, independent of the duty cycle at CLK.
All outputs can be enabled or disabled via a single output enable input. When the G input is high, the outputs
switch in phase and frequency with CLK; when the G input is low, the outputs are disabled to high impedance
state (3-state).
Unlike many products containing PLLs, the CDC857 does not require external RC networks. The loop filter for
the PLL is included on-chip, minimizing component count, board space, and cost.
Because it is based on PLL circuity, the CDC857 requires a stabilization time to achieve phase lock of the
feedback signal to the reference signal. This stabilization time is required following power up and application
of a fixed-frequency, fixed-phase signal at CLK, as well as following any changes to the PLL reference or
feedback signals. The PLL can be bypassed for test purposes by strapping AVCC to ground. If AVCC is at GND
and VCC = ON, 2 falling edges on G cause the PLL to run with FBOUT being enabled and all other outputs being
disabled, after AVCC ramps up to its specified VCC value, with G being kept low. The CDC857 is characterized
for operation from 0°C to 85°C.
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

DESCRIPTION
AGND
17
Ground
Analog ground. AGND provides the ground reference for the analog circuitry.
AVCC
16
Power
Analog power supply. AVCC provides the power reference for the analog circuitry. In addition, AVCC
can be used to bypass the PLL for test purposes. When AVCC is strapped to ground, PLL is bypassed
and CLK is buffered directly to the device outputs. During disable (G = 0), the PLL is powered down.
CLK
CLK
13
14
I
Clock input, CLK provides the clock signal to be distributed by the CDC857 clock driver. CLK is used
to provide the reference signal to the integrated PLL that generates the clock output signals. CLK
must have a fixed frequency and fixed phase for the PLL to obtain phase lock. Once the circuit is
powered up and a valid CLK signal is applied, a stabilization time is required for the PLL to phase
lock the feedback signal to its reference signal.
FBIN
FBIN
36
35
I
Feedback input. FBIN provides the feedback signal to the internal PLL. FBIN must be hard-wired
to FBOUT to complete the PLL. The integrated PLL synchronizes CLK and FBIN so that there is
nominally zero phase error between CLK and FBIN.
FBOUT
FBOUT
32
33
O
Feedback output. FBOUT is dedicated for external feedback. It switches at the same frequency as
CLK. When externally wired to FBIN, FBOUT completes the feedback loop of the PLL.
G
37
I
Output bank enable. G is the output enable for outputs Y and Y. When G is low outputs Y are disabled
to a high-impedance state. When G is high, all outputs Y are enabled and switch at the same
frequency as CLK.
