What Does It Do?

Vectron International's CD-700 is a user-configured, phase-locked loop (PLL) solution designed to simplify a wide variety of clock recovery and data retiming, frequency

translation, clock smoothing and clock switching applications. The device features a phase-lock loop ASIC with a quartz stabilized VCXO for superior stability and jitter

performance. This highly integrated module provides unsurpassed performance, reliability and quality. The proprietary ASIC device includes a refined Phase Detector, a Loop

Filter Op-Amp, a Loss of Signal Alarm with Clock Return to Nominal feature, a VCXO circuit, and an optional 2n divided output.

The ASIC and quartz resonator are housed in a hermetic 16-pad ceramic leadless chip carrier. The VCXO frequency (OUT1) and division factor (OUT2) are factory set in

accordance with customer specifications. PLL response is optimized for each application by the selection of external passive components. Software is available from Vectron

to aid in loop filter component selection and loop response modeling.

Parameter

Output Frequency (ording option)

Out 1, 5.0 V option

Out 1, 3.3 V Option

For input RZ data, Manchester encoded data,

and input clock recovery applications, the

output clock must run at two times the input

rate to ensure that the input is clocked

correctly. Since the output clock has a max-

imum frequency of 65.536 MHz, these inputs

are limited to a maximum rate of 32.768 MHz.

OUT2 is a binary submultiple of OUT1, or

it may be disabled.

A 0.01uF and 0.1 parallel capacitor should be

located as close to pin 14 (and grounded) as

possible

Figure 1 defines these parameters. Figure 2

illustrates the equivalent five gate TTL load and

operating conditions under which these

parameters are tested and specified. Loads

greater than 15 pF will adversely effect rise/fall

time as well as symmetry.

A loss of signal (LOS) indicator is set to a

logic high if no transitions are detected at

DATAIN after 256 clock cycles. As soon

as a transition occurs at DATAIN, LOS is

set to a logic low.

Symmetry is defined as (ON TIME/PERIOD with

Vs=1.4 V for both 5.0 V and 3.3 V operation.

Output terminal of internal operational amplifier.

Negative input terminal to internal operational amplifier.

Output signal produced by phase detector.

With LOSIN set to a logic high, the external input to the VCXO (VC) is

disabled and the VCXO returns to it’s nominal center frequency. With

LOSIN set to logic low, the external input to the VCXO is enabled. The

LOSIN input has an internal pull-down resistor.

When set to a logic low, output pins OUT1, OUT2, RCLK, and RDATA

buffers are set to high-impedance state. When set to a logic high or
