Pin Functions

PIN DESCRIPTION
NAME NO. TYPE
BIAS 10 O Bias voltage output for setting driver output power by external resistors
DIR 5 O Direction control output signal for bus arbitration
DIRSET1 7 — DIRSET1 and DIRSET2: Bits to set the duration of DIR
DIRSET[2:1]: [L:L] = 9.6 kbps; [L:H] = 38.4 kbps; [H:L] = 115 kbps; [H:H] = standby mode
DIRSET2 6 —
GND 8 — Ground
16
RES 9 P Input voltage to adjust driver output power that is set by external resistors from BIAS pin to GND
RXIN 11 I Modulated input signal to the receiver
RXOUT 4 O Digital data bit stream from receiver
SYNCOUT 1 O Open-drain output to synchronize other devices to the 4x-carrier oscillator at XTAL1 and XTAL2
TXIN 2 I Digital data bit stream to driver
TXOUT 12 O Modulated output signal from the driver
VCC 13 P Analog supply voltage for the device
VL 3 P Logic supply voltage for the device
XTAL1 14 I/O I/O pins of the crystal oscillator. Connect a 4 × fC crystal between these pins or connect XTAL1 to an 8.704-MHz clock and connect XTAL2 to GND.
XTAL2 15
EP — — Exposed pad. Connection to ground plane is recommended for best thermal conduction.
