HMC7043 3.2 GHz JESD204B Clock Distribution IC

Analog Devices' HMC7043 clock distribution IC is a high-performance, 14-output fanout buffer

Image of Analog Devices' HMC7043 Clock Distribution ICADI's HMC7043 is designed to meet the requirements of multi-carrier 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.

The HMC7043 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. The HMC7043 can generate up to seven DCLK and SYSREF clock pairs per the JESD204B interface requirements.

Features
  • JEDEC JESD204B support
  • Low additive jitter: <15 fs="" rms="" at="" 2457.6="" mhz="" (12="" khz="" to="" 20="">
  • Very low noise floor: -155.2 dBc/Hz at 983.04 MHz
  • Up to 14 LVDS, LVPECL, or CML type device clocks (DCLKs)
    • Maximum CLKOUTx/CLKOUTx and SCLKOUTx/SCLKOUTx frequency of 3200 MHz
    • JESD204B-compatible system reference (SYSREF) pulses
    • 25 ps analog and ½ clock input cycle digital delay independently programmable on each of 14 clock output channels
  • SPI-programmable adjustable noise floor vs. power consumption
  • SYSREF valid interrupt to simplify JESD204B synchronization
  • Supports deterministic synchronization of multiple HMC7043 devices
  • RFSYNC pin or SPI-controlled SYNC trigger for output synchronization of JESD204B
  • GPIO alarm/status indicator to determine the health of the system
  • Clock input to support up to 6 GHz
  • On-board regulator for excellent PSRR
  • 48-lead, 7 mm x 7 mm LFCSP package
Applications
  • JESD204B clock generation
  • Cellular infrastructure (multicarrier GSM, LTE, W-CDMA)
  • Data converter clocking
  • Phase array reference distribution
  • Microwave baseband cards
