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 V_CC 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 V_CC if not used.
Positive Phase-Adjust Input. Used to optimally align internal PLL phase. Attach to V_CC if not used.
Negative Filter Input. PLL loop filter connection.
Positive Filter Input. PLL loop filter connection.
