NATIONAL SEMICONDUCTOR LM7341 Manual
The LM7341 is a RRIO input and output amplifier in a small SOT-23 package with a wide supply voltage and temperature range. The amplifier has a 4.6 MHz gain bandwidth and a 1.9 volt per microsecond slew rate, and draws 0.75 mA of supply current at no load. The LM7341 is tested at -40°C, 125°C and 25°C with modern automatic test equipment. Detailed performance specifications at 2.7V, ±5V, and ±15V and over a wide temperature range make the LM7341 a good choice for automotive, industrial, and other demanding applications. The LM7341's input common mode range is greater than RRIO, with a minimum 76 dB of common mode rejection at ±15V, making it a good choice for both high side and low side sensing applications. The LM7341's performance is consistent over a wide voltage range, making the part useful for applications where the supply voltage can change, such as automotive electrical systems and battery powered electronics. The LM7341 uses a small SOT23-5 package, which takes up little board space, and can be placed near signal sources to reduce noise pickup.

NATIONAL SEMICONDUCTOR -LMK03000 Family Precision Clock Conditioner with Integrated VCO General Description
The LMK03000 family of precision clock conditioners combines the functions of jitter cleaning/reconditioning, multiplication, and distribution of a reference clock. The devices integrate a Voltage Controlled Oscillator (VCO), a high performance Integer-N Phase Locked Loop (PLL), a partially integrated loop filter, and up to eight outputs in various LVDS and LVPECL combinations. The VCO output is optionally accessible on the Fout port. Internally, the VCO output goes through a VCO Divider to feed the various clock distribution blocks. Each clock distribution block includes a programmable divider, a phase synchronization circuit, a programmable delay, a clock output mux, and an LVDS or LVPECL output buffer. This allows multiple integer-related and phase-adjusted copies of the reference to be distributed to eight system components. The clock conditioners come in a 48-pin LLP package and are footprint compatible with other clocking devices in the same family.
