The ANADIGICS ACA2604 amplifier for Fiber-to-the-Home (FTTH) applications is intended to be used in conjunction with the triplexer in fiber-coax line terminals. The device is driven by, and amplifies the output of, the video downstream path photodiode.
The high-impedance input of the ACA2604 eliminates the need for a costly transformer usually needed to interface to the photodiode, and a low equivalent input noise level offers excellent sensitivity. The device provides sufficient linearity to maintain low CTB and CSO levels in full-bandwidth (132 channel) systems, even across a wide gain adjustment range.
The ACA2604 is manufactured using ANADIGICS’s proven MESFET technology that offers state-of-theart reliability, temperature stability and ruggedness. The device operates from a single +5 V supply and is offered in a 5 mm x 5 mm x 1 mm surface mount package.

General Description
The AP2014 controller IC is designed to provide a low cost synchronous Buck regulator for on-board DC to DC converter applications. With the migration of today’s ASIC products requiring low supply voltages such as 1.8V and lower, together with currents in excess of 3A, traditional linear regulators are simply too lossy to be used when input supply is 5V or even in some cases with 3.3V input supply. The AP2014 together with dual N-channel MOSFETs such as AF9410, provide a low cost solution for such applications. This device features an internal 200KHz oscillator (400KHz for "A" version), under-voltage lockout for both Vcc and Vc supplies, an external programmable soft-start function as well as output under-voltage detection that latches off the device when an output short is detected.

*Synchronous Controller in 8-Pin Package
*Operating with single 5V or 12V supply voltage
*Internal 200KHz Oscillator (400KHz for AP2014A)
*Soft-Start Function
*Fixed Frequency Voltage Mode
*500mA Peak Output Drive Capability
*Protects the output when control FET is shorted
*SOP-8L/PDIP-8L Pb-Free package

*Graphic Card
*Hard Disk Drive
*DDR memory source sink Vtt application
*Low cost on-board DC to DC such as 5V to 3.3V, 2.5V or 1.8V

Peripheral Imaging Corporation's HSN series is family of self-scanning photodiode solid-state linear imaging arrays. These photodiode sensors employ PIC’s proprietary CMOS Image Sensing Technology to integrate the sensors into a single monolithic chip. These sensors are optimally designed for applications in spectroscopy. Accordingly, these sensors contain a linear array of photodiodes with an optimized geometrical aspect ratio (25-μm aperture pitch x 2500-μm aperture width) for helping to maintain mechanical stability in spectroscopic instruments and for providing a large light-capturing ability. The family of sensors consists of photodiode arrays of various lengths, 256, 512, and 1024 pixels.
The HSN photodiode arrays are mounted in 22-pin ceramic side-brazed dual-in-line packages that fit in standard DIP sockets. A diagram of its pinout configuration is seen in Figure 1.

*Selectable saturation charge capacities. 65-pC capacity for wider dynamic range. 25-pC for lower noise readout.
*Wide spectral response (180 – 1000 nm) for UV and IR response.
*NP junction photodiodes with superior resistance to UV damage.
*Low dark current.
*Integration time up to 11 seconds at room te mperature.
*Integration time extended to hours by cooling.
*Anti-blooming circuitry.
*High linearity.
*Low power dissipation (less than 1 mW).
*Geometrical structure for enhanced stability and registration.
*Standard 22-lead dual-in-line IC package.
