HMC704LP4E Analog Devices Profile
HMC704LP4E is a high-performance clock generator and distributor integrated circuit designed and manufactured by Analog Devices. It is a low-jitter clock generator that features 14 universal outputs, and it supports multiple input clock frequencies, including LVCMOS, LVDS, LVPECL, and CML. This IC also offers flexible frequency configuration options through its serial interface.
The HMC704LP4E integrates a PLL (Phase Locked Loop) that allows for generating an output frequency range from 25.6MHz to 3.6GHz. It can achieve a low jitter of fewer than 70 fs RMS (Root Mean Square) typical over the frequency range of 12kHz to 20MHz.
The HMC704LP4E has numerous applications in high-speed communications, test and measurement equipment, and radar systems. The device is available in a 48-pin LFCSP (Lead Frame Chip Scale Package), and requires almost no external components, making it suitable for compact designs.
Other HMC704LP4E features include adjustable differential outputs with amplitude between 200mV to 2V, configurable output polarity, and programmable output skew with a timing resolution of 4.4ps. The IC has a digital lock detection that ensures reliable and accurate clock synchronization on all outputs.
What Are The Alternative Parts For HMC704LP4E Analog Devices
There are several alternative parts available for the HMC704LP4E from Analog Devices. Some options include:
- LMK04828: This is a clock jitter cleaner and low-jitter clock generator from Texas Instruments. It features 14 universal outputs and supports multiple input clock frequencies, including LVCMOS, LVDS, LVPECL, and CML. It has a low RMS jitter of 120 fs typical over the frequency range of 12 kHz to 20 MHz, slightly higher than the HMC704LP4E.
- AD9528-4: This is a high-performance clock generator from Analog Devices, it has 14 outputs that can provide frequencies up to 3.6 GHz. It features jitter-cleaning technology and supports multiple input clock frequencies, including LVCMOS, LVDS, and LVPECL, but it lacks support for CML input.
- ICS844021-01: This is a clock generator from Renesas Electronics. It features 4 outputs that can provide frequencies up to 250 MHz. It supports single-ended input clocks and features differential OE pins for power-down control of each output.
- Si5324-0x: This is a clock generator from Silicon Labs that can provide frequencies up to 1.4 GHz. It features 4 outputs and supports LVCMOS or LVDS input clocks.
It is important to note that these alternatives may not offer the exact same features as the HMC704LP4E, and they may have different output frequencies or jitter characteristics. It is important to review the specifications of the alternative clock generators thoroughly to determine which device is best suited for the intended application.
