MOTOROLA
J8:
BCLKT = BCLK
J8 connects BCLK to BCLKT (Pin 12) of the PCM Codec–Filter.
J9:
NOT AVAILABLE
J10A: MU–LAW SELECT/HIGH–PASS FILTER BYPASS
J10A selects Mu–Law on the MC14LC5480, MC145481, and MC145484. On the
MC145482 and MC145483, this jumper enables the high–pass filter bypass for frequency
response down to DC for the transmit ADC conversion.
J10B: A–LAW SELECT/HIGH–PASS FILTER BYPASS DISABLE
J10B selects A–Law on the MC14LC5480, MC145481, and MC145484. On the MC145482
and MC145483, this jumper disables the high–pass filter bypass.
J11A: SPKR– = RO–
J11A connects RO– (Pin 2) to the RJ11 and the receive output BNC connector.
J11B: SPKR– = PO+
J11B connects PO+ (Pin 5) to the RJ11 and the receive output BNC connector.
J12:
NOT AVAILABLE
J13:
NOT AVAILABLE
J14:
NOT AVAILABLE
J15:
NOT AVAILABLE
J16:
FST = FSYNC
J16 connects the on–board generated FSYNC to the PCM Codec–Filter (Pin 14) FST as
well as Pin 1 of the 2x20 connector (P13).
J17A: POWER–UP
J17A connects the PDI (Pin 10) of the PCM Codec–Filter to VDD to power–up the device.
J17B: POWER–DOWN
J17B connects the PDI (Pin 10) of the PCM Codec–Filter to VSS to power–down the device.
J18:
DT = DR
J18 connects the data transmit (DT Pin 13) to the data receive (DR Pin 8) of the PCM Co-
dec–Filter.
