Press Release Summary:
Suited for HART field instruments and masters, Model SD2015 uses phase continuous frequency shift keying at 1,200 bps and operates in half duplex mode per HART protocol. Typical current consumption at 25°C ambient is 110 µA at 5 V and 90 µA at 3.3 V. Together with external passive components, CMOS single chip modem IC provides all functions needed to meet HART requirements including modulation, demodulation, receiving filtering, carrier detect, and transmit signal wave shaping.

HART Modem IC Offers Lower Current Consumption
November 25, 2008 - Hangzhou SDIC Microelectronics Co. Ltd. announced a new HART modem IC - SD2015, that brings to a new level of performance in low current consumption and low Bit Error Rate (< 1 ppm). The SD2015 is fully compatible with A5191HRT or HT2015 ICs.
The SD2015 is a CMOS single chip modem IC used in HART (Highway Addressable Remote Transducer) field instruments and masters. This IC, together with a few external passive components provide all functions needed to meet HART physical requirements including modulation, demodulation, receiving filtering, carrier detect, and transmit signal wave shaping.
The SD2015 uses phase continuous FSK (Frequency Shift Keying) at 1200bps, and operates in half duplex mode per HART protocol. Typical current consumption at 25oC ambient is 110µA at 5V and 90µA at 3.3V, both are lower than any existing HART modem IC. Bit Error Rate (BER) is less than 1 ppm, which is one hundred times lower than the HART requirement.
The SD2015 is available in Model SD2015A (PLCC28) and Model SD2015B (LQFP32). For product information and download, please visit our website at sdicmicro.com/eng/icproduct.html or contact us via email at sales@sdicmicro.com.
