Hello,
The datasheet for the LMK1C1102 has performance specifications for VDD=+3.3V, +2.5V and +1.8V.
The hardware I am developing on has VDD=+3.0V.
Is the LMK1C1102 able to operate with VDD=+3.0V?
If so, is it reasonable to expect that when the LMK1C1102 is operated with VDD=+3.0V that its performance will be similar to the VDD=+3.3V performance specification or be close to or exceed the VDD=+2.5V performance specification?
Or for some reason is it just not recommended to operate the LMK1C1102 from VDD=+3.0V?
If I consider the VDD=2.5V specification but use VDD=3.0V then both the device driving the LMK1C1102 and driven by the LMK1C1102 both operate from VDD=+3.0V
Oscillator Module output specification at VDD=+3.0V
Vout High: 0.9xVdd = 2.7V
Vout low: 0.1xVdd = 0.3V
LMK1C1102 (using VDD=+2.5V specification but calculated using VDD=+3.0V)
Vin High: 0.7xVdd = 2.1V
Vin low: 0.3xVdd = 0.9V
Vout High: 0.8xVdd = 2.4V
Vout low: 0.2xVdd = 0.6V
FPGA 3.0V Input specification at VDD=+3.0V
Vin High (min): 1.7V
Vin low (max): 0.8V
Seems like it should work to me, but I am after confirmation that the LMK1C1102 can work from +3.0V with performance that is as good as the +2.5V performance specification.
Regards,
Tom
