NATIONAL SEMICONDUCTOR LM117/LM317A/LM317 3-Terminal Adjustable Regulator Manual

The LM117 series of adjustable 3-terminal positive voltage regulators is capable of supplying in excess of 1.5A over a 1.2V to 37V output range. They are exceptionally easy to use and require only two external resistors to set the output voltage. Further, both line and load regulation are better than standard fixed regulators. Also, the LM117 is packaged in standard transistor packages which are easily mounted and handled. In addition to higher performance than fixed regulators, the LM117 series offers full overload protection available only in IC's. Included on the chip are current limit, thermal overload protection and safe area protection. All overload protection circuitry remains fully functional even if the adjustment terminal is disconnected. Normally, no capacitors are needed unless the device is situated more than 6 inches from the input filter capacitors in which case an input bypass is needed. An optional output capacitor can be added to improve transient response. The adjustment terminal can be bypassed to achieve very high ripple rejection ratios which are difficult to achieve with standard 3-terminal regulators. Besides replacing fixed regulators, the LM117 is useful in a wide variety of other applications. Since the regulator is “floating” and sees only the input-to-output differential voltage, supplies of several hundred volts can be regulated as long as the maximum in

NATIONAL SEMICONDUCTOR DS15EA101 0.15 to 1.5 Gbps Adaptive Cable Equalizer with LOS Detection Manual

The DS15EA101 is an adaptive equalizer optimized for equal- izing data transmitted over copper cables. It operates over a wide range of data rates from 150 Mbps to 1.5+ Gbps and automatically adapts to equalize any cable length from zero meters to lengths that attenuate the signal by 35 dB at 750 MHz. It allows either single-ended or differential in- put drive, which enables equalization of coaxial cables as well as differential twin-ax and twisted pair cables. It also features an LOS output and an output en- able which, when tied together, disable the output when no signal is present. The DS15EA101 is powered from a single 3.3V supply and consumes 210 mW at 1.5 Gbps. It operates over the full −40°C to +85°C industrial temperature range and is available in a space saving 4 x 4 mm LLP-16 package which allows for high density placement of components in multi-channel ap- plications.

NATIONAL SEMICONDUCTOR LMH6515 Manual

The LMH6515 is a high performance, digitally controlled variable gain amplifier (DVGA) that combines precision gain control with a low noise, ultra-linear, differential amplifier. It is typically used to drive a high performance ADC in a wide range of mixed signal and digital communication applications, such as mobile radio and cellular base stations, where automatic gain control (AGC) is required to increase system dynamic range. When used in conjunction with a high speed ADC, the system dynamic range can be extended by up to 32 dB. The LMH6515 has a differential input and output, allowing for large signal swings on a single 5V supply. It is designed to accept signals from RF elements and maintain a terminated impedance environment. The input impedance is 200Ω resistive. The output impedance can be selected as either 200Ω or 400Ω. A unique internal architecture allows for use with both single ended and differential input signals. The input signals to the LMH6515 are scaled by a highly linear, digitally controlled attenuator with 31 accurate 1 dB steps. The attenuator output provides the input signal for a high gain, ultra-linear differential transconductor. The transconductor's differential output current can be converted into a voltage by using the on-chip 200Ω or 400Ω loads. The transconductance gain is 0.1 Amp/Volt, resulting in a maximum voltage gain of +26 dB when driving a 200Ω load.
