HMC7043LP7FE

HMC7043LP7FE is a high performance, fanout buffer. It is designed to meet the requirements of multicarrier GSM and LTE base station designs, and offers a wide range of clock management and distribution features to simplify baseband and radio card clock tree designs. It provides 14 low noise and configurable outputs to offer flexibility in interfacing with many different components in a base transceiver station (BTS) system, such as data converters, local oscillators, transmit/receive modules, field programmable gate arrays (FPGAs), and digital front-end ASICs. It can generate upto seven DCLK and SYSREF clock pairs per the JESD204B interface requirements. The system designer can generate a lower number of DCLK and SYSREF pairs, and configure the remaining output signal paths for independent phase and frequency. It is used in applications such as cellular infrastructure (multicarrier GSM, LTE, W-CDMA), data converter clocking, phase array reference distribution, microwave baseband cards.

• RMS additive jitter is 15fs rms typical at (fCLKOUT = 2457.6MHz, BW = 12kHz to 20MHz)
• Absolute phase noise (offset = 20MHz) is -155.2dBc/Hz typ at (fCLKOUT = 983.04MHz)
• JESD204B-compatible system reference (SYSREF) pulses
• SPI-programmable adjustable noise floor vs power consumption
• SYSREF valid interrupt to simplify JESD204B synchronization
• RFSYNCIN pin or SPI-controlled SYNC trigger for output synchronization of JESD204B
• GPIO alarm/status indicator to determine system health
• Clock input to support upto 6GHz
• Operating temperature range from -40°C to +85°C
• Package style is 48-lead lead frame chip scale [LFCSP]
