• Main Purpose: Audio, CODEC
• Utilized Ic / Part: W681360
• Lead Free Status / RoHS Status: Lead free by exemption / Not applicable
• Secondary Attributes: -
• Embedded: -
• Primary Attributes: -

J3: Power Supply Input Jack (5VDC or 3VDC) If you are evaluating a 5V product use
5VDC power supply. If you are evaluating a 3V product use a 3VDC power supply
adapter with positive center.
J4: GND TST points
J5: Side Tone (SW3-6)
J5 enables the side tone path on the PCM CODEC filter
J6: VAG CAP ENABLE: (SW4-1)
J6 enables VAG filter cap
J7: Transmitter Audio Input
J8: RJ9 Handset connector.
J9A: 2.5V Reference Voltage (SW3-7)
J9A is not used.
J9B: SPKR+ = PAO
(SW3-8)
J9B connects pin 4 W6810/W681310/W681360 to the RJ9 handset
J10: A-Law and µ-Law Selection or High-pass Bypass: (SW4-2) & (SW4-3)
J10A Selects µ-Law and J10B Selects A-Law for W6810/W6811/W681310/W681512.
For W681360 J10 is used for High-pass Bypass. Determines if the transmit high-pass
filter is used (HB=’0’) or bypassed (HB=’1’). When the high-pass is bypassed the
frequency response extends to DC.
J11: 2x20 pin Header:
This 40-pin header provides access to W6810/W681310/W681360 analog and digital
signals for a user defined system, or a second W681xxxDK evaluation system for back-
to-back operation.
J12A: SPKR- = R0- (SW4-4)
J12A connects RO- (Pin 2) to the RJ9 and the RX output connector.
J12B: SPKR-=PA0+ (SW4-5)
J12B connects PA0+ (Pin 5) to the RJ9 and the RX output connector.
