CMX602B PRELIMINARY INFORMATION
6.1.3 Operating Characteristics
For the following conditions unless otherwise specified:
VDD = 2.7V at TAMB = 10°C to 60°C and VDD = 3.0V to 5.0V at TAMB = -40°C to 85°C
Xtal Frequency = 3.579545MHz ± 0.1%, 0dBV corresponds to 1.0VRMS
DC Parameters
IDD (ZP input high) at VDD = 5.0V
IDD (ZP input low) at VDD = 3.0V
IDD (ZP input low) at VDD = 5.0V
Logic 1 input level
(RXCLK and XTAL inputs)
Logic 0 input level
(RXCLK and XTAL inputs)
Logic input leakage current
(VIN = 0 to VDD) excluding XTAL input
Output logic 1 level (lOH = 360µA)
Output logic 0 level (lOL = 360µA)
IRQ output 'off' state current
(VOUT = VDD)
Schmitt Trigger input thresholds
(Figure 16)
High going (VtHI)
Low going (VtLO)
Tone Alert Detector
'Low' tone nominal frequency
'High' tone nominal frequency
Start of Tone Alert signal to DET high time
(tDTON Figure 9)
End of Tone Alert signal to DET and IRQ
low time (tDTOFF Figure 9)
DET high time to ensure IRQ goes low
(tQCAS see Figure 9)
To ensure detection:
'Low' tone frequency deviation from
nominal
'High' tone frequency deviation from
nominal
Tone level of each simultaneously
applied tone
2750Hz tone level with respect to
2130Hz
tone level
Signal to Noise ratio
Dual Tone Burst Duration for DET output
Dual Tone Burst Duration to ensure IRQ
goes low
