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 multistage 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...
