Part Number : MAX19700
Function : 7.5Msps, Ultra-Low-Power Analog Front-End
Package : QFN 48 Pin Type
Maker : Maxim Integrated
Pinouts : 
Description :
The MAX19700 is an ultra-low-power, mixed-signal analog front-end (AFE) designed for TD-SCDMA handsets and data cards. Optimized for high dynamic performance at ultra-low power, the MAX19700 integrates a dual 10-bit, 7.5Msps receive (Rx) ADC, dual 10-bit, 7.5Msps transmit (Tx) DAC with TD-SCDMA baseband filters, and three fast-settling 12-bit aux-DAC channels for ancillary RF front-end control. The typical operating power in Tx-Rx FAST mode is 36.3mW at a 5.12Msps clock frequency.
The Rx ADCs feature 54.9dB SINAD and 78dBc SFDR at a 1.87MHz input frequency with a 7.5Msps sample frequency. The analog I/Q input amplifiers are fully differential and accept 1.024VP-Pfull-scale signals.Typical I/Q channel matching is ±0.22° phase and±0.02dB gain.
