Operational Description
The DSC2042 is a dual oscillator with an HCSL
output and an LVPECL output. The device
consists of a MEMS resonator and a support
PLL IC. The two outputs are generated
through independent 8-bit programmable
dividers from the output of the internal PLL.
Two constraints are imposed on the output
frequencies: 1) f2=M x f1/N, where M and N
are even integers between 4 and 254, 2)
1.2GHz < N x f2 < 1.7GHz.
The actual frequencies output by the DSC2042
are controlled by an internal pre-programmed
memory (OTP). This memory stores all
coefficients required by the PLL for up to eight
different frequency combinations. Three
control pins (FS0 FS2) select the output
frequency combination. Discera supports
customer defined versions of the DSC2042.
Standard frequency options are described in in
the following sections.
When Enable (pin 1) is floated or connected to
VDD, the DSC2042 is in operational mode.
Driving Enable to ground will tri-state both
output drivers (hi-impedance mode).
