FUNCTION
Positive Offset-Correction Loop Capacitor Input
Negative Offset-Correction Loop Capacitor Input
Received-Signal-Strength Indicator Output
Supply Ground
Op Amp Inverting Input. Attach to ground if op amp is not used.
Voltage Threshold Input. Threshold voltage for loss-of-power monitor. Attach to VCC if LOP function
is not used.
Loss-of-Power Output, TTL. Limiting amplifier loss-of-power monitor. Asserts high when input signal
is below threshold set by VTH.
Positive Supply Voltage
Negative Serial-Clock Output, PECL, 622.08MHz. SDO- is clocked out on the falling edge of SCLKO-.
Positive Serial-Clock Output, PECL, 622.08MHz. SDO+ is clocked out on the rising edge of SCLKO+.
Negative Serial-Data Output, PECL, 622.08Mbps
Positive Serial-Data Output, PECL, 622.08Mbps
Loss-of-Lock Output, TTL. PLL loss-of-lock monitor, active low (see Design Procedure).
Negative Phase-Adjust Input. Used to optimally align internal PLL phase. Attach to VCC if not used.
Positive Phase-Adjust Input. Used to optimally align internal PLL phase. Attach to VCC if not used.
Negative Filter Input. PLL loop filter connection.
Positive Filter Input. PLL loop filter connection.
Positive Digital Data Input, PECL, 622.08Mbps serial-data stream
Negative Digital Data Input, PECL, 622.08Mbps serial-data stream
Input Select. Connect to GND to select digital data inputs or VCC for analog data inputs.
