MPCD

Descriptions

The Pico Macom MPCD is a frequency agile professional grade, microprocessor controlled

CATV mini demodulator. The unit accepts any NTSC television signal in the 54-806MHz

frequency-range converting it to baseband video and audio, while maintaining over 60dB

S/N ratio. Up to 12 or 16 units can be installed “mix-and-match” in Pico’s MPC12, MPS12,

MPC12R and MPC16 chassis with MPCM45 and MPCMA mini-modulators. Its unique

design enables it to be installed in other manufacturers’ mini-mod chassis. The unit’s phase-

locked-loop frequency control, envelope signal detection, and superior SAW filtering mini-

mize adjacent channel interference and assure accurate and spurious free performance.

IRC or HRC offsets can be activated via push-button switches on the front panel. The unit’s

PLL circuitry in conjunction with the non-volatile memory contained in the microprocessor

ensures easy and reliable channel selection and restoration. The MPCD demodulator is

shipped with all internal adjustments preset. Pico Macom backs up this product with its

industry leading 5-year limited warranty.

OPERATION AND CARE

Do’s & Don’ts

•Always operate in a cool well-ventilated environment.

•Always provide a stable, conditioned power source.

•Heed all safety warnings and obey all environmental and electrical oper-

ating requirements.

•To clean, use a damp cloth only and clean only with mild soap.

•Do not use solvents or harsh detergents.

•Do not use this product for purposes other than intended.

HEADEND/DISTRIBUTION INTERFACE

PICO MACOM recommends connecting the headend components in the

following manner:

Each of the modulators, signal processors or strip amplifiers output are con-

nected to a combining network. Either a PHC-12G or a PHC-24G headend

combiner may be used to accomplish this purpose. When demodulators are

used, the baseband audio and video outputs are connected to the baseband

audio and video inputs of a modulator.

The PHC-12G or PHC-24G passive headend combiner consists of two rows

of directional couplers combined by a hybrid splitter. Normally, the odd chan-

nels are combined on one row while even

channels are combined on the other row of

directional couplers for maximum isolation.

The output of the combiners may be

connected to the input of a launch amplifier

such as a CA-30RK550 or CA-30RK1000. The

output of the amplifier is connected to the

main distribution line.

A 24 channel system hook-up is shown. (The

same combining result may be accomplished

by using a single PHC-24G). The two PHC-

12G outputs are combined via a two-way

splitter, which is connected to a CA-30RK1000

launch amplifier. The input levels to the com-

biner, whether from a modulator, signal

processor or a strip amplifier, must be at the

same amplitude.
