CLC5958
14-bit, 52MSPS A/D Converter
September 1999
General Description
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.
Features
• 14-bit
• 52MSPS
• Ultra-wide dynamic range
Noise floor: -72dBFS
SFDR: 90dB
• Excellent performance to Nyquist
• IF sampling capability
• Very small package: 48-pin CSP
• Programmable output levels:
3.3V to 5V
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°C to +85°C is guaranteed. National Semiconductor tests
each part to verify compliance with the guaranteed specifications.
Applications
• Multi-channel basestations
• Multi-standard basestations:
GSM, WCDMA, DAMPS, etc.
• Smart antenna systems
• Wireless local loop
• Wideband digital communications
