CSP1027 Datasheet | Lucent Technologies

Features s ∆-Σ (delta-sigma) A/D and D/A converters with standard 16-bit serial I/O interface. s On-chip filters meet ITU-T G.712 voice band frequency response and signal to distortion plus noise specifications. Suitable for IS-54, GSM, and JDC digital cellular applications. s Low-profile package (<1.5 mm) 48-pin thin quad flat pack (TQFP) available or 44-pin EIAJ quad flat pack (QFP). s Operates in systems with a 3.0 V to 5.0 V digital power supply and a 5.0 V analog supply. s Low-power 0.9 µm CMOS technology, fully static design, typical power of 68 m W when active and 0.05 m W in standby with a 3.3 V digital supply and a 5.0 V analog supply. s A low-power inactive (standby) state without stopping clock or removing power supply. s Sampling rates up to 24 k Hz. s On-chip programmable sampling clock generator allows input clock to be an integer multiple of 125 times the sampling rate or...
