- ADI’s AD8372 VGA features industry-best accuracy, gain control and noise figure, allowing cable providers to keep pace with commercial and residential demands for increased bandwidth.

Norwood, MA(2/12/2008) - Analog Devices, Inc. (ADI) is introducing a general-purpose two-channel, digitally controlled VGA (Variable-gain amplifier) developed with specific features for today’s CMTS (Cable Modem Termination System) upstream receiver applications. The two-channel AD8372 VGA enables designers to incorporate more CMTS channels while simultaneously improving modem performance and the quality of upstream cable signals. The new VGA’s space-saving design reduces component count and board area by allowing designers to fit more channels into a given space or pack the same number of channels into a smaller area.

For wide-dynamic-range applications, the AD8372 offers a broad 41-dB gain range, with 1-dB steps and 0.2-dB resolution. The gain is programmed through a bidirectional 4-pin, 8-bit serial port, which consists of clock, latch, data input and data output lines for each channel. The 41-dB control range enables designers to keep input signals above the noise floor, while using the full-scale range of a wider variety of ADCs (analog-to-digital converters). The 41-dB gain range makes the AD8372 an essential component for multiple cable applications, including CMTS.

The AD8372, which accepts differential inputs and provides differential outputs, requires no baluns. It provides better than 77-dBc second and third harmonic distortion (HD) and 55-dB common-mode rejection (CMR). Compared to competitive products, the AD8372 delivers 35 percent more gain control range and improved second harmonic distortion in roughly 20 percent of the board space.

Availability and Pricing
The AD8372 amplifier is now shipping in production quantities and is available in a compact, thermally enhanced 5-mm × 5-mm 32-lead LFCSP (lead-frame chip scale package). The device operates over a temperature range of –40 degrees Celsius to +85 degrees Celsius. The AD8372 is priced at $6.50 per unit in 1,000-piece quantities.

- ADI’s AD8260 digital VGA and driver sets new output benchmark with greater than ±200-mA drive capability, while integrating three discrete functions for industrial and automotive cabling applications.

Norwood, MA(2/6/2008) - Analog Devices, Inc. (ADI), a global leader in high-performance semiconductors for signal processing applications and market leader in amplifier ICs, today introduced a digitally programmable VGA (variable gain amplifier) with transmit driver that sets a new standard of performance for driving signals over power lines, cables, and other applications with low impedance. The AD8260 operates on a single 3.3-V power supply and has a transmit driver that produces ±200-mA output up to 100 kHz, and greater than ±100-mA above that frequency. This is an improvement over competing solutions using a discrete VGA, output driver and pre-amp, which consume 90 percent more board space, and require multiple power supplies.

The AD8260 VGA operates at -3dB bandwidth of 200-MHz and includes a 30-dB gain range digitally adjustable in 3-dB gain steps providing the headroom needed for losses introduced in various cabling systems. The new VGA features 2.4nV/rtHz input voltage noise and driver with a built-in gain of 1.5, which is ideal for converting DAC (digital-to-analog converter) differential output signals to a voltage that can directly drive very low impedances. The AD8260 can fully drive a 10  load with 2 Vpp at 10 MHz. In addition, the chip dissipates just 93 mW of power, which is less than half that of competing devices.

More About the AD8260
The AD8260 includes a high-current driver, usable as a transmitter, and a low-noise digitally programmable VGA, which is useable as a receiver, combined in a 5 mm x 5 mm chip-scale package. The receiver section consists of a single-ended input preamplifier and linear-in-dB, differential-output VGA. The differential output facilitates the interface to modern low-voltage, high-speed ADCs (analog-to-digital converters). Versatile single- and dual-supply operation allow gain control of negative-going pulses, such as generated by photodiodes or photo-multiplier tubes, and allows for the processing of band-pass signals on a single supply. The AD8260 preamplifier is user-configurable with external resistors for gains greater than 6 dB.
The driver is set-up to be driven by modern current output DACs, like the high-speed AD9742 12 bit, 3.3 V supply DAC.

Pricing and Availability
The AD8260 is sampling now, with full volume production scheduled for March 2008. The AD8260 is available in a 32-Lead LFCSP (lead-frame chip-scale package) over the extended industrial temperature range -40C to 105C and is priced at $3.79 in 1,000-unit quantities.

- ADI’s video decoder combines 12-bit 3D comb filtering with 1080p-HD 150 MSPS digitizer in a single-chip system, reducing design overhead while improving fine picture detail.

Norwood, MA(1/21/2008) - Analog Devices has expanded its Advantiv™ advanced television portfolio with a new 12-bit resolution 3D comb video decoder with an integrated 150 MSPS digitizer for Full-HD 1080p input formats. The ADV7802 provides system designers with a complete single-chip solution for improving video image and color quality in advanced high-definition televisions (HDTVs), video-processors, audio/video receiver (AVR) systems and DVD recorders. The new 12-bit 3D comb video decoder offers superior processing resolution for motion detection and 3D comb filtering operations, versus existing video decoder solutions, enabling designers to reduce trade-offs between image sharpness and Y/C separation performance – something that has traditionally been reserved for professional and studio broadcast applications – without the added cost and design complexity of discrete chip solutions.

The ADV7802 is the industry’s only true 12-bit-resolution decoder with 4:4:4 sampling throughout the processing pipeline, including support for RGB SCART inputs, to provide designers with a higher level of system performance compared to existing 8-bit industry offerings using 4:2:2 sampling schemes. The addition of an on-chip interface with support for
SDR (single data-rate) DRAM reduces overall system cost while support for DDR (double data-rate) DRAM enables simultaneous 12-bit 3D comb (NTSC or PAL), digital noise reduction (DNR) and time base correction (TBC), providing designers with a complete solution for decoding standard-definition (SD) video for noisy off-air broadcast signals or poor-quality VCR tape recordings with unstable timing.

The ADV7802’s multi-format conversion capability allows designers to easily convert analog video signals to create the vivid images, deeper colors and enhanced digital imaging features that consumers have come to expect in their video-processing and digital-TV applications. For TV chassis designs targeted to multiple end markets, the ADV7802 automatically detects and performs 3D comb filtering for a wide range of video standards in all regions, including all variants of NTSC and PAL. Advanced SECAM decoding is also supported. In addition, support for detecting and decoding weak terrestrial TV broadcast signals has been improved to ensure the best possible picture, even under remote reception conditions.

Leveraging ADI’s superior analog-to-digital (ADC) converter technology and advanced adaptive Y/C separation algorithms, the highly integrated single-chip solution provides high-end video performance with its 3-tap, zero field latency 3D comb filter which operates on the full PAL field sequence. The ADV7802’s 3D adaptive comb filter produces sharper, more accurate color reproduction, while the decoder’s enhanced 12-bit YCbCr or RGB output capability (with interlaced or conversion to progressive scan timing) enhances a system’s HDMI™ (High Definition Multimedia Interface™) Deep Color processing capabilities - even for analog input sources.
