Operational Description
The DSC2130/2230 is a LVDS oscillator
consisting of a MEMS resonator and a support
PLL IC. The LVDS output is generated
through independent 8-bit programmable
dividers from the output of the internal PLL.
DSC2130/2230 allows for easy programming
of the output frequencies using I2C/SPI
interface. Upon power-up, the initial output
frequency is controlled by an internal pre-
programmed memory (OTP). This memory
stores all coefficients required by the PLL for
two different default frequencies. The control
pin (FS) selects the initial frequency. Once
the device is powered up, a new output
frequency can be programmed. Programming
details are provided in the Programming
Guide. Standard default frequencies are
described in the following sections. Discera
supports customer defined versions of the
DSC2130/2230.
When Enable (pin 1) is floated or connected to
VDD, the DSC2130/2230 is in operational
mode. Driving Enable to ground will disable
both output drivers (hi-impedance mode).
