Interfacing TMS320VC5510 to SBSRAM (Rev. A)
Texas InstrumentsThe TMS320C55x™ (C55x™) External Memory Interface (EMIF) supports a glueless interface to high-density and high-speed synchronous burst static random access memories (SBSRAM). For clocking SBSRAMs, the EMIF can operate at numerous C55x DSP CPU clock output frequency multiples. Examples are given for system-level connection and register configuration for the different types of SBSRAM memory supported.
Driving Capacitance with the THS4001
Texas InstrumentsOperational amplifiers (op amps) are often used to drive devices that have significant input capacitance such as analog-to-digital converters, cables, MOSFETs, filter networks, etc. The effect of the capacitance is extra phase shift in the loop gain of the amplifier. This phase shift erodes the phase margin of the amplifier and may lead to instability. At high frequency, even a very small capacitance is detrimental.
This paper reports a simple method for restoring amplifier stability while driving capacitive loads with the THS4001.
