Active splitter ICs enable multi-output
boxes
Active splitters for use in CATV set-top boxes with multiple tuners incorporate highly linear low-noise amplifiers to drive multiple output paths.
Anadigics has released three new active splitters for use in CATV set-top boxes with multiple tuners The APS3608, APS3611 and APS3623 all incorporate highly linear low-noise amplifiers to drive multiple output paths, each of which provides a very low distortion connection to either an analogue video or a digital video tuner

Amplifier supports faster Docsis datarates
Device supports high linear power levels, which enable channel bonding and thus higher datarates in the cable system upstream (return) path.
Integrated tuner eases switch to digital
Device provides the low noise and low distortion performance required for CATV systems that combine digital and analogue channels using a densely loaded spectrum.
"The development of three new splitter products clearly demonstrates Anadigics' commitment to the subscriber side of the broadband marketplace", remarks Ron Michels, Senior Vice President and General Manager of Anadigics' Broadband Business.
"These products are integral to RF front-end solutions, including those that support MoCA functionality".
"MoCA allows consumers to tap into the vast amount of unused bandwidth available through existing in-home coaxial wiring".

Balanced low noise linear power amplifiers improve performance for CATV set-top box, distribution and drop applications.
"This extra bandwidth enables the seamless networking of multiple entertainment devices".
Anadigics' APS3608 is a three-way active splitter with differential inputs and outputs and integrated gain control.
The device provides 5dB typical noise figure at 5.5dB gain, and the three output paths can be controlled individually, with each providing 29dB of gain control range.
The APS3608 has a flat gain profile over its 50 to 1100MHz operating frequency band.
The device delivers excellent second and third order distortion performance, with typical CTB/CSO of -70dBc and typical crossmodulation (XMOD) of -67dBc.
The APS3611 is a two-way active splitter with single-ended inputs and outputs that operates to 870MHz, and has a special frequency/gain profile designed to compensate for in-band attenuation caused by MoCA line filters.
It has a low noise figure of 5dB, a fixed gain of 3dB, and a current adjust pin for optimising distortion performance.
The intermodulation distortion performance of the device is similar to the APS3608, with a CTB of -74dBc, CSO of -67dBc and XMOD of -66dBc.
The highly linear, low noise APS3623 is a three-way active splitter with single-ended inputs and outputs.
It is optimised for compatibility with MoCA bands over 1GHz, and supports both analogue and digital channel line-ups.
With a CTB of -77dBc and a CSO of -65dBc, the linearity/distortion performance of the device is best in class.
Both the APS3611 and the APS3623 were designed for MoCA-enabled set-top boxes, but also support multiple-tuner TV, TV tuner card and broadband media centre applications.
The APS3608 is available now at a price of US $3.54 in quantities of 5000 units.
