NXP CATV C-family User Manual
NXP CATV C-family
for the Chinese
SARFT standard
Connecting people,
protecting your network
Specially designed for the Chinese Hybrid Fiber Coax (HFC) infrastructure, NXP CATV C-family
offers you a total solution for cable TV networks. It is both flexible enough for connecting rural
communities as part of China’s ‘Connecting every village’ program and powerful enough for
upgrading major cities from analog to high-end digital services. All C-type devices are compliant
with the Chinese State Administration for Radio, Film and Television (SARFT) standard, and cover
most HFC applications in the 550 - 870 MHz range.

GaAs HFET dies for high end devices
Further extending our high quality CATV portfolio, this new
family lets you address an even wider range of
HFC applications. Dedicated solutions for the implementation
of CATV systems in China, our C-type devices deliver the
performance you need for modern TV infrastructures.
The BGY588C, BGE788C and BGD712C devices cover
the frequency range from 550 MHz to 750 MHz. Extending
the C-family portfolio into the high-end segment,
the CGD944C, CGD942C, CGY888C and BGO807C operate
between 40 MHz and 870 MHz and have been specifically
tested under Chinese raster conditions. Manufactured using
our GaAs HFET die process, the CGD942C and CGD944C are
high-gain, high-performance 870 MHz power doublers.
They are capable of satisfying the demanding requirements
of top-end applications including high-power optical nodes.
Our GaAs HFET MMIC dies are providing ‘by design’
the best ESD protection levels with no needs for external
TVS components normally used with GaAs pHEMT devices.
All CATV C-type devices feature a transparent cap that makes
it easy to distinguish them from counterfeit products.

module such as BGY588C for 550 MHz, BGE788C for 750 MHz
and CGY888C for 870 Mhz systems. These modules are fitting
perfectly in the Chinese ‘Connecting to Every Village’ projects.
BGD712C
The BGD712C is a 750 MHz, 18 dB power doubler module.
It has been designed for 750 MHz optical nodes including
ordinary or optical receivers and distribution amplifiers.
It can also be used in line extender amplifiers together with
a 750 MHz push-pull module, such as BGY785A or BGY787.
As such it can be used widely in Chinese ‘Connecting to Every
Village’ projects.
