CLC5958

The CLC5958 is a monolithic 14-bit, 52MSPS analog-to-digital converter. The ultra-wide dynamic range and high sample rate of the device make it an excellent choice for wideband receivers found in multi-channel basestations. The CLC5958 integrates a low distortion track-and-hold amplifier and a 14-bit multi-stage quantizer on a single die. Other features include differential analog inputs, low jitter differential clock inputs, an internal bandgap voltage reference, and CMOS/TTL compatible outputs. The CLC5958 is fabricated on the National ABIC-V 0.8 micron BiCMOS process.

The CLC5958 features a 90dB spurious free dynamic range (SFDR) and a 70dB signal to noise ratio (SNR). The balanced differential analog inputs ensure low even-order distortion, while the differential clock inputs permit the use of balanced clock signals to minimize clock jitter.

The 48-pin CSP package provides an extremely small footprint for applications where space is a critical consideration. The package also provides a very low thermal resistance to ambient. The CLC5958 may be operated with a single +5V power supply. Alternatively, an additional supply may be used to program the digital output levels over the range of +3.3V to +5V. Operation over the industrial temperature range of -40 to +85 is guaranteed. National Semiconductor tests each part to verify compliance with the guaranteed specifications.
