Introduction

The SI5338C-B02035-GMR is a programmable, ultra-wideband clock IC designed for frequency converter applications and other RF/timing systems requiring wideband clock synthesis and low jitter performance. This device has two banks of four differential output pairs and one oscillator output. It features a wide tuning range and numerous integrated features, including a jitter attenuator and spread spectrum engine, making it ideal for application-specific radio applications such as WiMAX and LTE.

Application Field

The SI5338C-B02035-GMR provides frequency conversion applications and other RF/timing systems a programmable, ultra-wideband clock IC. It is ideal for application-specific radio applications such as WiMAX, LTE and various military system designs. For WiMAX systems, the SI5338C-B02035-GMR is able to generate clocks for the transmit side and receiver side of the system. The wide tuning range allows for a wide range of frequency synthesis that can be used for various device generations and various applications. On the receiver side, it can be used to generate the clock necessary to sample the RF input of the WiMAX system, enabling the digital baseband to receive the input digitally. On the transmit side, the wide tuning range allows for the generation of the carrier wave necessary for modulating the output signal.For LTE systems, the SI5338C-B02035-GMR is able to generate clocks for the eNodeB transmit/receive, UE transmit/receive, PDCCH control messages, and many other clocks associated with the LTE system. It can also be used to generate clocks for the fronthaul, backhaul, and other associated systems often found in LTE networks. These clocks are important to sourcing the proper data rate associated with each messaging type and maintaining low jitter performance in those transmissions. The SI5338C-B02035-GMR is used in a variety of military systems for frequency synthesis and jitter attenuation such as digital HF communication, software defined radios and communication interface circuits. Its wide tuning range and integrated jitter attenuating helps to ensure low jitter performance in systems requiring frequency agility such as software defined radios in which the SI5338C-B02035-GMR can help to rapidly reconfigure the system in the midst of a transmission or while in receipt of transmissions.

Working Principle

The SI5338C-B02035-GMR uses a dual bank architecture with four differential ouput pairs to provide up to 8 different clocks. This device supports a wide frequency tuning range of 0.5 to 560 MHz and 4.20 GHz, and low power consumption. The low power consumption is enabled by integrated fractional-N frequency synthesis which allows the device to synthesize intermediate frequencies that could not be otherwise synthesized by an integer-N PLL. The SI5338C-B02035-GMR also has an integrated jitter attenuator, which helps to ensure low jitter performance for ultimately more reliable data transmission with higher accuracy data synchronization. This is especially important for application-specific radio systems such as WiMAX and LTE which require precise data transmissions. The integrated jitter attenuator helps to make sure performance is not degraded by jitter.The SI5338C-B02035-GMR has a spread spectrum engine, making it ideal if low electromagnetic interference (EMI) is important in the system design. The spread spectrum engine is easy to set up with pre-programmable profiles, which eases development and ensures low EMI. The SI5338C-B02035-GMR is housed in a 17.8 x 21.1 mm surface-mount package, making it easy to integrate into various systems. It is available in extended temperature ranges of -40 to 85⁰C and -40 to 105⁰C, making it suitable for extreme environmental conditions.
