General Description
The CLC5955 is a monolithic 11-bit, 55MSPS analog-to-digital
converter. The device has been optimized for use in IF-sampled
digital receivers and other applications where high resolution,
high sampling rate, wide dynamic range, low power dissipation,
and compact size are required. The CLC5955 features differential
analog inputs, low jitter differential universal clock inputs, a low
distortion track-and-hold with 0-300MHz input bandwidth, a bandgap
voltage reference, data valid clock output, TTL compatible CMOS
(3.3V or 2.5V) programmable output logic,
and a proprietary multi-
stage quantizer. The CLC5955 is fabricated
on the ABIC-V 0.8
micron BiCMOS process.
The CLC5955 features a 74dBc spurious free dynamic range
(SFDR) and a 64dB signal to noise ratio (SNR). The wideband
track-and-hold allows sampling of IF signals to greater than
250MHz. The part produces two-tone, dithered, SFDR of 83dBFS
at 75MHz input frequency. The differential analog input provides
excellent common mode rejection, while the differential universal
clock inputs minimize jitter. The 48-pin TSSOP package provides
an extremely small footprint for applications where space is a
critical consideration. The CLC5955 operates from a single +5V
power supply. 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.
