Which ULP PHY is Better ?Which ULP PHY is Better ? Consequences of Low on-Current Design - Data-speed: Low Data-rate - RTC (Active/Sleep): Low Duty-cycle (~ 1/100) - Low Tx Power: Shorter Coverage - Low Rx Sensitivity: Shorter Coverage - Simple PHY: Required High SNR Shorter Coverage - Limited Choice for Transceiver Architecture
Consequences of Optimum on-Current Design - Data-speed: High Data-rate - RTC (Active/Sleep): Very Low Duty-cycle (~ 1/1000) - Allow moderate Tx Power: Longer Coverage - Allow High Rx Sensitivity: Longer Coverage - Optimum PHY: Required Low SNR Longer Coverage - Variety of Choice for Optimum Transceiver ArchitectureRTC: Real-Time Clock

UPL Design Consideration UPL Design Consideration SoC - MODEM: Clock Frequency / ADC-DAC Precision - Architecture: Low IF vs Baseband - Digital: Chip Area (Deep sub-Micron) vs Leakage Current - Event Driven Clocking Manager - Dual X-Tal: System Clock and RTC Clock - Optimum Data-rate: MODEM Speed vs RF/Analog on-Time - RF Blocks: Low-Power / Low-Leakage RF IP (AMP, LNA, PLL, Up-Down)
Module - Longer Batt. Life: Linear (LDO) vs SMPS - Power Switch (Optional): Reduce Leakage Current - Power Capacitor: Sufficient Capacity for on-Time Supply - RTC SynchronismLDO: Low Drop-Out, SMPS: Switching-Mode Power Supply
