The CDCI6214 device is an ultra-low power clock generator. The device selects
between two independent reference inputs to a
phase-locked
loop and generates up to four different frequencies on configurable differential output channels
and also a copy of the reference clock on a LVCMOS output channel.
Each of the four output channels has a configurable integer / fractional output
divider and a dedicated integer divider.
Together with the output muxes, this allows up to five different frequencies.
Clock distribution dividers are reset in a deterministic
way for clean clock gating and glitch-less update capability.
Flexible power-down options allow
to optimize the device for lowest power consumption in active and standby operation. Typically four
156.25 MHz LVDS outputs consume 150 mW at 1.8V. Typical RMS jitter of 386 fs for 100 MHz HCSL
output enhances system margin for PCIe applications.
The CDCI6214 is configured using internal registers
that are accessed by an I2C-compatible serial interface and internal
EEPROM.
The CDCI6214 enables high-performance clock trees
from a single reference at ultra-low power with a small footprint.
The factory- and user-programmable EEPROM make the CDCI6214
ideal as
easy-to-use, instant-on clocking solution with low power consumption.
